Question: 401

HOTSPOT

A customer built a computer for gaming, sourcing individual components and then assembling the system. The OS starts up, but within a few minutes the machine locks up. The customer brought the computer to a technician to diagnose the issue.

Answer:

Explanation: correct answer is “Overclocking” and “Reduce CPU Clock speed” CPU is at 4.5 Ghz when normal is 3.2 Ghz. Overclocking too much can cause freezes, and this is a gaming computer so the user probably took it too far. 

Question: 402

DRAG DROP

A customer recently experienced a power outage at a SOHO. The customer does not think the components are connected properly. A print job continued running for several minutes after the power failed, but the customer was not able to interact with the computer.

Once the UPS stopped beeping, all functioning devices also turned off. In case of a future power failure, the customer wants to have the most time available to save cloud documents and shut down the computer without losing any data.

Question: 405

An end user is printing, but the image is being cut off because the paper is too small. The user did put the correct type of paper in the printer. Which of the following should the user change first?

  1. The image size
  2. The quality of the image
  3. The tray settings
  4. The file type

Answer: C

Explanation:

When a printout is being cut off, CompTIA A+ Core 1 (220-1201) troubleshooting emphasizes checking the simplest, most likely configuration mismatch first—the printer’s paper size/source settings. Even if the user physically loaded the correct paper, the print job can still be formatted incorrectly if the printer driver, application, or printer itself is set to use a different paper size or a different tray. If the printer thinks it is using a smaller paper size (or a tray configured for smaller paper), it may clip the printable area and truncate the image at the edges.

Changing tray settings (paper size and paper source) aligns the printer’s configuration with the actual media installed, which is a standard first-step for issues related to formatting, clipping, and page boundaries. Image quality (DPI) affects sharpness, not cropping. File type rarely causes consistent edge cutoff compared with page setup mismatches. Adjusting image size could work as a workaround, but CompTIA best practice is to correct the paper/tray and page setup settings first so all prints format properly without editing the document each time.

Question: 406

A company requires a storage solution that combines performance and redundancy for a main database server with high levels of read/write operations. Which of the following storage configurations best meets these requirements?

  1. RAID 0
  2. RAID 5
  3. RAID 6
  4. RAID 10

Answer: D

Explanation:

For a main database server with high read/write activity, the best RAID choice must deliver strong performance while still providing fault tolerance. Per CompTIA A+ Core 1 (220-1201) storage/RAID objectives, RAID 10 (1+0) combines disk mirroring (RAID 1) and disk striping (RAID 0). Striping improves performance by distributing read/write operations across multiple disks, which is ideal for databases that perform frequent transactions. Mirroring provides redundancy by keeping an identical copy of data on a paired drive, allowing the system to tolerate drive failures (typically one drive per mirrored pair) without data loss.

RAID 0 is fast but offers no redundancy, making it inappropriate for critical servers. RAID 5 and RAID 6 use parity, which provides redundancy but introduces a write penalty because parity must be calculated and written during updates—often a poor fit for workloads with heavy random writes like databases. RAID 6 is even more write-intensive

Question: 407

A technician is building a custom CAD workstation with a high-end graphics card. The customer requests that the system has the highest possible stability. Which of the following is the best choice for the power supply?

  1. UPS
  2. Redundant
  3. Surge protector
  4. Modular

Answer: B

Explanation:

For the highest possible stability, the best power-supply choice is a redundant power supply. In CompTIA A+ Core 1 (220-1201) hardware concepts, redundant PSUs are used in systems where uptime and reliability are critical. A redundant PSU configuration typically includes two power supply units operating together (often in a hot-swappable bay). If one PSU fails, the other continues supplying power, allowing the workstation to remain operational and preventing unexpected shutdowns that could interrupt CAD work or corrupt data. This directly matches the requirement for maximum stability.

A UPS improves resilience to power loss and brownouts by providing battery backup and line conditioning, but it is not a power supply type and doesn’t protect against the PSU itself failing. A surge protector helps guard against voltage spikes, but it also does not ensure system operation if the PSU fails. A modular PSU mainly improves cable management and airflow by allowing detachable cables; it can be convenient and neat, but it does not inherently increase stability compared with redundancy. Therefore, the most stability-focused PSU option is Redundant.

Question: 408

A user’s computer is connected to a docking station at their desk. The user cannot access the department file servers even though the docking station has a hardwired connection. Which of the following steps should a technician take to restore the user’s access?

  1. Update the docking station firmware.
  2. Restart the computer.
  3. Disable Wi-Fi.
  4. Replace the Ethernet cable.

Answer: C

Explanation:

In CompTIA A+ Core 1 (220-1201) networking and troubleshooting, a common cause of “can’t reach internal resources” while docked is that the laptop is still using the wireless interface (or has a higher interface priority for Wi-Fi) instead of the docking station’s wired Ethernet connection. If the Wi-Fi network is a guest/isolated VLAN, uses different routing, or has stricter access controls, the user may be blocked from reaching department file servers even though an Ethernet cable is physically connected to the dock. Disabling Wi-Fi is a fast, low-risk step that forces the system to use the wired NIC path through the docking station, which typically provides the correct corporate network access, DHCP scope, and routing to internal servers.

Restarting the computer might help in some cases, but it’s less targeted and not the “best next step” when the likely issue is interface selection. Replacing the Ethernet cable is appropriate if link lights are off or the wired connection is clearly down, but the scenario highlights that the dock has a hardwired connection—suggesting the physical layer may be fine. Dock firmware updates are not a first-line fix for basic connectivity/access symptoms.

Question: 409

A company’s directory services server is located on premises. Which of the following best describes the directory services infrastructure?

  1. Hybrid cloud
  2. Private cloud
  3. Public cloud
  4. Community cloud

Answer: B

Explanation:

In the CompTIA A+ Core 1 (220-1201) exam objectives, cloud deployment models describe how and where computing resources are hosted and who has access to them. A private cloud is defined as a cloud environment that is dedicated to a single organization and may be hosted on-premises within the company’s own data center or in a dedicated external facility. Since the question states that the directory services server is located on premises, it indicates that the organization is hosting and managing its own infrastructure internally. This aligns directly with the definition of a private cloud deployment model.

Directory services—such as Microsoft Active Directory or LDAP-based services—are commonly deployed internally to manage user authentication, authorization, group policies, and resource access within an organization. When these services run on company-owned hardware inside the organization’s network, the infrastructure remains under the organization’s full administrative control, security policies, and management.

The other options do not match this scenario. A public cloud is hosted by third-party providers and shared among multiple customers. A hybrid cloud combines on-premises infrastructure with public cloud services. A community cloud is shared by multiple organizations with similar requirements. Because the system is hosted internally for a single organization, the correct classification is Private Cloud .

Question: 410

Which of the following is a characteristic of a Type 1 hypervisor?

  1. Host OS required
  2. Bare-metal server installation
  3. Lightweight OS
  4. Local configuration options

Answer: B

Explanation:

According to the CompTIA A+ Core 1 (220-1201) virtualization objectives, a Type 1 hypervisor is known as a bare-metal hypervisor because it installs directly onto the physical hardware of a system rather than running on top of a traditional operating system. This architecture allows the hypervisor to manage hardware resources—such as CPU, memory, storage, and networking—without the overhead of a host operating system. Because of this direct interaction with the hardware, Type 1 hypervisors typically provide higher performance, better scalability, and improved stability compared to Type 2 hypervisors.

Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V (bare-metal deployment),and Citrix XenServer. These hypervisors are commonly used in enterprise data centers, cloud infrastructure, and large virtualization environments where multiple virtual machines must run efficiently on a single physical server.

Option A (Host OS required) describes a Type 2 hypervisor, such as VMware Workstation or Oracle VirtualBox, which runs on top of an existing operating system. Option C (Lightweight OS) may describe some hypervisor environments but is not the defining characteristic. Option D (Local configuration options) is also not specific to Type 1 hypervisors.

Therefore, the key characteristic that defines a Type 1 hypervisor is that it performs a bare-metal server installation directly on the hardware

Question: 411

A help desk technician investigates a laser printer issue. Smudges are appearing on the printed pages, but they are not present on the document that was sent to the printer. Which of the following should the technician do first to diagnose the issue?

  1. Use a different kind of printing paper.
  2. Inspect the printer drum.
  3. Update the printer firmware.
  4. Replace the toner.

Answer: B

Explanation:

Because the smudges are not in the original document, CompTIA A+ troubleshooting logic indicates the problem is occurring inside the print process, not in the application or file. For laser printers, smudging commonly points to an issue with the imaging components—especially the drum/photoconductor unit (and sometimes the fuser). A+ Core 1 (220-1201) printer troubleshooting emphasizes starting with the most likely, easiest-to-verify causes before replacing parts. Inspecting the drum is a diagnostic step that can reveal visible defects such as scratches, toner buildup, contamination, or worn surfaces that cause toner to transfer incorrectly, leading to streaks or smears on output.

Replacing the toner (D) is a corrective action and may be unnecessary if the drum is damaged. Changing paper type (A) can help with some issues (like poor fusing or humidity-related problems), but it’s less directly tied to consistent smudges caused by the imaging process. Firmware updates (C) Are rarely the first step for print-quality defects; they’re more relevant to compatibility, bugs, or feature issues—not physical smearing. Therefore, inspecting the printer drum first best matches A+ methodology and common laser printer failure points.

Question: 412

A company’s directory services server is located on premises. Which of the following best describes the directory services infrastructure?

  1. Hybrid cloud
  2. Private cloud
  3. Public cloud
  4. Community cloud

Answer: B

Explanation:

In CompTIA A+ Core 1 (220-1201) cloud concepts, the key differentiator between cloud deployment models is where the service is hosted and who owns/uses the underlying infrastructure. If a company’s directory services server (for example, a domain controller providing authentication/authorization and centralized identity management) is located on premises, that points to infrastructure that is owned and operated by the organization for its own internal use. This aligns best with a private cloud model, which is defined as cloud resources dedicated to a single organization and can be implemented on-premises (internally hosted) or in a dedicated off-site environment.

It is not a public cloud because public cloud services are hosted by a third-party provider and shared across multiple customers. It is not hybrid cloud because hybrid requires a mix of on-prem resources and public cloud resources working together (the question only specifies on-prem). It is not community cloud because that involves shared infrastructure among multiple organizations with common needs.

Question: 413

Which of the following display technologies is known for offering the highest contrast ratios?

  1. LCD
  2. LED
  3. OLED
  4. QLED

Answer: C

Explanation:

CompTIA A+ Core 1 (220-1201) display technology objectives emphasize that contrast ratio is strongly influenced by how well a screen can produce true black. OLED (Organic Light-Emitting Diode) panels are known for the highest contrast ratios because each pixel is self-emissive—meaning it generates its own light. When an image requires black, OLED can turn individual pixels completely off, producing near-perfect black levels and extremely high (often “infinite”) contrast in practical terms.

By comparison, LCD panels require a backlight, so black areas still allow some light leakage through the liquid crystal layer, reducing contrast. LED in this context is typically an LED-backlit LCD, not a fundamentally different pixel technology; it improves brightness and efficiency but still relies on backlighting, so contrast is limited by backlight bleed and panel design. QLED is also a type of LCD technology that uses a quantum dot layer to enhance color and brightness, but it still uses a backlight, so it cannot match OLED’s per-pixel shutoff for black levels. Therefore, OLED is the best choice for the highest contrast ratios.

Question: 414

A company is separating its accounting department’s network from its customer service department’s network. Which of the following will accomplish this task?

  1. VPN
  2. DNS
  3. VLAN
  4. DHCP

Answer: C

Explanation:

A VLAN (Virtual Local Area Network) is the correct solution because it logically separates devices into different broadcast domains on the same physical switching infrastructure. In CompTIA A+ Core 1 (220-1201), VLANs are described as a way to segment a network for security, performance, and management—for example, isolating departments like Accounting and Customer Service so their traffic is separated. Devices assigned to different VLANs cannot communicate directly at Layer 2; communication between VLANs requires a Layer 3 device (such as a router or a Layer 3 switch) using inter-VLAN routing and appropriate access control. This effectively prevents unnecessary broadcast traffic from crossing department boundaries and helps enforce separation policies.

A VPN is used to create an encrypted tunnel over an untrusted network (commonly for remote access or site-to-site connectivity), not for internal departmental segmentation. DNS resolves hostnames to IP addresses and does not isolate networks. DHCP automatically assigns IP configuration (IP address, gateway, DNS servers), but it does not provide segmentation by itself.

Therefore, implementing VLANs is the best way to separate the two departments’ networks.

Question: 415

Which of the following devices forwards data between different networks by analyzing the headers of packets?

  1. Hub
  2. Router
  3. Repeater
  4. Unmanaged switch

Answer: B

Explanation:

A router is a network device that forwards data between different networks by examining packet headers, specifically the IP address information contained in Layer 3 (Network Layer) of the OSI model. According to the CompTIA A+ Core 1 (220-1201) networking objectives, routers use routing tables and packet header analysis to determine the best path for data to travel from a source network to a destination network. When a packet arrives at a router interface, the router reads the destination IP address in the packet header, compares it against its routing table, and then forwards the packet to the appropriate next hop or network interface. This function allows routers to connect multiple networks such as LANs, WANs, and the internet.

The other options do not perform this function. A hub operates at Layer 1 (Physical Layer) and simply broadcasts incoming signals to all connected ports without inspecting any packet information. A repeater also operates at the physical layer and is used only to regenerate or amplify signals to extend network distance. An unmanaged switch operates mainly at Layer 2 (Data Link Layer) and forwards frames based on MAC addresses, not IP packet headers. Because only routers analyze packet headers and forward traffic between different networks, Router is the correct answer.

Question: 416

Which of the following is a characteristic to consider when selecting a satellite internet connection?

  1. Necessary proximity to urban infrastructure
  2. eSIM requirement
  3. Line of sight to nearby tower
  4. Increased latency

Answer: D

Explanation:

In the CompTIA A+ Core 1 (220-1201) networking concepts, satellite internet is commonly associated with higher (increased) latency compared with terrestrial options like cable, fiber, or DSL. Latency is the delay between sending data and receiving a response. With satellite, signals must travel from the user’s dish up to a satellite and then back down to a ground station (and return again for responses). That long travel distance adds noticeable delay, which can affect real-time activities such as VoIP, video conferencing, and online gaming. Even though newer low-earth-orbit (LEO) systems can reduce latency compared with older geostationary systems, satellite service is still generally discussed in A+ as having higher latency characteristics to consider.

The other options do not best fit satellite internet. Proximity to urban infrastructure (A) is more relevant to cable/fiber availability. An eSIM requirement (B) relates to cellular/mobile service, not satellite broadband. Line of sight to a nearby tower (C) describes cellular or fixed wireless services that depend on tower connectivity; satellite instead needs a clear view of the sky toward the satellite (not a nearby tower). Therefore, increased latency is the best characteristic to consider.

Question: 417

A technician is migrating an application server to another server. Which of the following DNS records should the technician create to ensure seamless connectivity?

  1. TXT
  2. SPF
  3. DKIM
  4. CNAME

Answer: D

Explanation:

To ensure seamless connectivity during (and after) migrating an application server, the best DNS approach in CompTIA A+ Core 1 (220-1201) terms is to use a CNAME (Canonical Name) record, which creates an alias from one hostname to another. Instead of users connecting directly to a server’s changing hostname, they connect to a consistent service name (for example, app.company.com).

That name can be configured as a CNAME pointing to the current host (such as server1.company.com). When the application is moved to a new server, the technician updates what the alias ultimately resolves to (or updates the target host’s A/AAAA record), and clients continue using the same familiar application URL/name—minimizing disruption and avoiding the need to reconfigure endpoints across devices.

The other record types are not designed for this purpose. TXT records store text-based information (often verification or policy data). SPF and DKIM are email authentication-related mechanisms (typically implemented via TXT records) used to validate authorized mail senders and message integrity—not application server migration. Because the goal is maintaining a stable name for a service while the underlying host changes, CNAME is the correct record type.

Question: 418

Which of the following supports the most devices due to its status as a legacy technology?

  1. 2.4GHz
  2. 5GHz
  3. 6GHz
  4. NFC

Answer: A

Explanation:

The correct answer is A. 2.4GHz.

In the CompTIA A+ Core 1 220-1201 networking objectives, wireless networking technologies include frequency bands such as 2.4GHz, 5GHz, and 6GHz, along with related concepts like channels, regulations, channel selection, Bluetooth, 802.11 standards, NFC, and RFID.

The 2.4GHz band supports the most devices because it is the oldest and most widely adopted Wi-Fi frequency listed. Many legacy devices, including older laptops, printers, IoT devices, smart home devices, and wireless peripherals, still rely on 2.4GHz. It also has better range and wall penetration than higher-frequency bands, although it is usually more crowded and slower. Why the other options are incorrect: B . 5GHz

5GHz is newer than 2.4GHz and generally provides faster speeds with less interference, but it does not support as many older legacy devices.

C . 6GHz

6GHz is the newest Wi-Fi frequency option used with newer Wi-Fi standards, so it has the least legacy device support among the Wi-Fi frequency choices.

D . NFC

NFC is a short-range communication technology, not a Wi-Fi frequency band. It is used for closeproximity functions such as tap-to-pay, pairing, and access cards, so it is not the best answer.

Final Answer: A. 2.4GHz

Question: 419

Which of the following is the best option to maintain a stable, tethered connection between a cell phone and a laptop?

  1. Bluetooth
  2. USB
  3. Hotspot
  4. NFC

Answer: B

Explanation:

The correct answer is B. USB

In the CompTIA A+ Core 1 (220-1201) objectives under mobile devices and connectivity methods, tethering refers to sharing a mobile device’s internet connection with another device such as a laptop. There are several tethering methods, including USB tethering, Bluetooth tethering, and Wi-Fi hotspot.

USB tethering is considered the most stable and reliable (tethered) connection because: It uses a physical cable connection, eliminating wireless interference.

It provides consistent bandwidth and low latency.

It also charges the phone while connected, which is an added benefit.

It is less prone to disconnections compared to wireless methods.

Why the other options are incorrect:

A . Bluetooth

Bluetooth tethering is slower and less stable due to limited bandwidth and susceptibility to interference. It is not ideal for high-performance or stable connections.

C . Hotspot

A mobile hotspot uses Wi-Fi, which is wireless, not tethered. While convenient, it is less stable than a wired USB connection and can be affected by interference and signal range.

D . NFC

NFC (Near Field Communication) is used for very short-range communication like payments or quick pairing. It is not used for maintaining a continuous network connection.

Final Answer: B. USB

Question: 420

Which of the following RAM characteristics allows for recovery from data faults in memory modules?

  1. Capacity
  2. Speed
  3. ECC
  4. DDR
  5. Parity

Answer: C

Explanation:

The correct answer is C. ECC (Error-Correcting Code).

In the CompTIA A+ Core 1 (220-1201) hardware objectives, RAM types and features include technologies designed to improve reliability and data integrity.

ECC memory is specifically designed to detect and correct data errors (faults) in memory automatically. It uses additional bits to store error-checking information, allowing the system to: Detect single-bit and some multi-bit errors

Automatically correct errors without system interruption

Improve system stability, especially in servers and critical systems

This makes ECC the best choice for recovering from data faults.

Why the other options are incorrect:

A . Capacity

Capacity refers to how much data the RAM can hold (e.g., 8GB, 16GB). It has nothing to do with error detection or correction.

B . Speed

Speed (measured in MHz or MT/s) affects performance but does not provide any fault recovery capability.

D . DDR

DDR (Double Data Rate) refers to the generation/type of RAM (e.g., DDR3, DDR4, DDR5). It improves performance but does not handle errors.

E . Parity

Parity memory can detect errors but cannot correct them. Since the question specifically asks for recovery from faults, ECC is the correct answer because it both detects and corrects errors.

Final Answer: C. ECC

Question: 421

A company needs to print several copies of a multipage document with the least consumption of resources possible. Which of the following settings will best accomplish this task?

  1. Duplex
  2. Orientation
  3. Tray settings
  4. Quality

Answer: A

Explanation:

The correct answer is A. Duplex.

In the CompTIA A+ Core 1 (220-1201) exam objectives under printer settings and configuration, duplex printing refers to printing on both sides of the paper automatically.

Using duplex printing is the best way to reduce resource consumption because:

It cuts paper usage in half, which is the primary resource being conserved.

It is ideal for multi-page documents and multiple copies.

It reduces physical storage and handling requirements.

Why the other options are incorrect:

B . Orientation

Orientation (portrait or landscape) changes the layout of the document but does not reduce resource usage.

C . Tray settings

Tray settings determine which paper tray is used (e.g., plain paper, letterhead), but they do not impact resource consumption.

D . Quality

Print quality (draft, normal, high) may affect ink/toner usage, but it does not reduce paper consumption as effectively as duplex printing, which is the main resource concern in this scenario.

Final Answer: A. Duplex

Question: 422

A company rolls out a mandatory OS update to all PCs. A legacy application that one department uses does not function on the new OS and is EOL. Which of the following should a technician suggest to solve the issue with minimal data loss, expense, and disruption to the users?

  1. Setting up a bare-metal hypervisor to isolate the outdated OS
  2. Moving to a supported system under a Type 2 hypervisor
  3. Upgrading to an alternative product and importing the data
  4. Uploading the database to a private cloud

Answer: B

Explanation:

The correct answer is B. Moving to a supported system under a Type 2 hypervisor.

In the CompTIA A+ Core 1 (220-1201) objectives, virtualization is a key concept for maintaining compatibility with legacy systems. A Type 2 hypervisor (hosted hypervisor) runs on top of an existing operating system and allows users to run a virtual machine (VM) with an older OS.

This solution is ideal because: It allows the legacy application to run in its required OS environment. It avoids replacing the application (which could cause data loss or compatibility issues). It is cost-effective, as it uses existing hardware. It minimizes user disruption, since users can continue using the application within a VM.

Why the other options are incorrect:

A . Setting up a bare-metal hypervisor

A Type 1 (bare-metal) hypervisor is more complex, costly, and disruptive. It typically requires dedicating hardware and is not ideal for a single department use case.

C . Upgrading to an alternative product and importing the data

Although this may be a long-term solution, it involves higher cost, potential data loss, retraining, and disruption.

D . Uploading the database to a private cloud

This does not solve the compatibility issue of the legacy application with the new OS.

Final Answer: B. Moving to a supported system under a Type 2 hypervisor

Question: 423

Which of the following RAM characteristics allows for the most data bandwidth?

  1. CAS latency
  2. ECC
  3. High clock speed
  4. Dual channel

Answer: D

Explanation:

The correct answer is D. Dual channel.

In the CompTIA A+ Core 1 (220-1201) hardware objectives, memory bandwidth refers to the amount of data that can be transferred between RAM and the CPU in a given amount of time.

Dual channel memory architecture increases bandwidth by:

Allowing the memory controller to access two memory modules simultaneously

Effectively doubling the data transfer rate compared to single-channel configurations

Improving overall system performance, especially in memory-intensive tasks

Why the other options are incorrect:

A . CAS latency

CAS latency measures the delay before data is available after a request. Lower latency improves response time, but it does not significantly increase total bandwidth.

B . ECC

ECC (Error-Correcting Code) improves reliability by detecting and correcting errors, but it does not increase data transfer bandwidth.

C . High clock speed

Higher clock speed does increase bandwidth, but not as significantly as enabling dual channel, which allows parallel data transfer paths and provides a greater overall increase.

Final Answer: D. Dual channel

Question: 424

Which of the following video cables uses an analog signal?

  1. DVI
  2. VGA
  3. USB-C
  4. HDMI

Answer: B

Explanation:

The correct answer is B. VGA.

VGA (Video Graphics Array) is an analog video interface. It transmits video signals as continuous electrical waves, which means the signal can degrade over distance or due to interference. VGA uses a 15-pin connector and is considered legacy hardware in modern systems, but it is still important for CompTIA A+ because you may encounter it in older equipment.

Why the other options are incorrect:

A . DVI

DVI can support both digital and analog signals, but in most modern contexts and exam questions, it is primarily treated as a digital interface (especially DVI-D). Since the question asks for a clearly analog cable, VGA is the best answer.

C . USB-C

USB-C is a digital interface that can carry video signals using protocols like DisplayPort Alternate Mode. It does not transmit analog video.

D . HDMI

HDMI is a fully digital interface used for high-definition video and audio transmission. It does not support analog signals.

Exam Tip (Core 1 220-1201):

Analog video = VGA

Digital video = HDMI, DisplayPort, USB-C, most DVI types

Final Answer: B. VGA

Question: 425

An employee is on a business trip and needs to upload daily conferences and meetings to the company’s intranet. The uploading process is successful but was faster in the past.

Which of the following is the most likely reason for the slowdown?

A. Wireless is turned off.

B. 5G is disabled.

C .Roaming is turned on.

D. Data is being throttled.

Answer: D

Explanation:

The correct answer is D. Data is being throttled.

Data throttling refers to the intentional slowing down of internet speeds by a mobile carrier after a user reaches a certain data usage limit or during network congestion. In this scenario, the employee can still successfully upload files, but the speed has decreased compared to before—this is a classic symptom of throttling.

Why the other options are incorrect:

A . Wireless is turned off

If wireless were turned off, the employee would not be able to upload anything at all. The question clearly states that uploads are still successful.

B . 5G is disabled

Disabling 5G could reduce speeds slightly if the device falls back to 4G/LTE, but it would not typically cause a significant or noticeable degradation unless compared under ideal conditions. It is not the most likely cause.

C . Roaming is turned on

Roaming allows connectivity outside the home network. While it may incur additional charges, it does not inherently cause significant speed reduction in most modern networks. It is less likely than throttling.

Exam Tip (Core 1 220-1201):

Slow but working connection → Think throttling or congestion

No connection → Think disabled wireless or network issues

Final Answer: D. Data is being throttled

Question: 426

A company updates its office with a new multifunction printer. Users report issues when they try to use scan-to-email functionality. The technician must ensure this feature is properly enabled. Which of the following should the technician do to resolve this issue?

  1. Adjust the SMTP server configurations for email.
  2. Check the printer’s IP address configuration.
  3. Install the printer’s driver software on all computers.
  4. Configure user authentication settings for email access.

Answer: A

Explanation:

The correct answer is A. Adjust the SMTP server configurations for email.

Scan-to-email functionality on a multifunction printer relies on proper configuration of an SMTP (Simple Mail Transfer Protocol) server. The printer must know how to send outgoing email, which requires settings such as:

SMTP server address

Port number (commonly 25, 465, or 587)

Authentication credentials (username/password)

Encryption method (SSL/TLS if required)

If scan-to-email is not working, the most common cause is incorrect or missing SMTP configuration.

Without this setup, the printer cannot send scanned documents via email.

Why the other options are incorrect:

B . Check the printer’s IP address configuration

This ensures network connectivity, but since the printer is already in use and the issue is specific to email functionality, IP configuration is unlikely the root cause.

C . Install the printer’s driver software on all computers

Drivers are needed for printing from computers, but scan-to-email is handled directly by the printer and does not depend on client-side drivers.

D . Configure user authentication settings for email access

While authentication may be required in some setups, it is part of the broader SMTP configuration.

The primary and most direct fix is ensuring SMTP settings are correct.

Exam Tip (Core 1 220-1201):

Scan-to-email issues → Check SMTP settings first

Multifunction printers rely on network services (email protocols), not just drivers

Final Answer: A. Adjust the SMTP server configurations for email

Question: 427

A client requests a new computer for high-performance video editing and virtual reality applications.

The technician must select a compatible motherboard for an Intel Core i9 processor and multiple graphics cards. Which of the following should the technician do to meet the client’s needs?

  1. Choose a cooling system capable of handling high thermal output.
  2. Use DDR3 RAM for increased compatibility.
  3. Verify there are two PCIe x1 slots for additional devices.
  4. Select a motherboard with integrated graphics to support video output.

Answer: A

Explanation:

The best answer provided is A, although it is important to note that the question is somewhat misleading because it asks about motherboard selection but provides mostly incorrect or irrelevant motherboard-related options.

For high-performance workloads such as video editing and virtual reality (VR) using an Intel Core i9 processor and multiple graphics cards (multi-GPU setup), system design considerations include high power consumption and significant heat output. In the CompTIA A+ Core 1 220-1201 objectives under hardware planning and troubleshooting, high-performance CPUs and multiple GPUs require adequate thermal management solutions, including advanced cooling systems (air or liquid cooling) to ensure system stability and prevent thermal throttling.

Why A is the best answer:

High-end CPUs like Intel Core i9 and multiple GPUs generate substantial heat.

Proper cooling is essential for maintaining performance under sustained load (video rendering, VR workloads).

While not strictly a motherboard feature, cooling is a critical system requirement for such a build.

Why the other options are incorrect:

B . Use DDR3 RAM for increased compatibility

Incorrect because modern Intel Core i9 platforms use DDR4 or DDR5, not DDR3, which is obsolete and incompatible with current high-performance motherboards.

C . Verify there are two PCIe x1 slots for additional devices

Incorrect because PCIe x1 slots are used for low-bandwidth devices (sound cards, network cards), not graphics cards.

Multiple GPUs require PCIe x16 slots, not x1.

D . Select a motherboard with integrated graphics to support video output

Incorrect because high-performance systems with discrete GPUs rely on those GPUs for rendering.

Integrated graphics are unnecessary and sometimes disabled when a dedicated GPU is installed.

Exam Insight (CompTIA A+ perspective):

In real-world A+ Core 1 scenarios, the correct motherboard selection for this requirement would focus on:

Multiple PCIe x16 slots (for multi-GPU support)

Compatible socket for Intel Core i9

Support for modern RAM (DDR4/DDR5)

Adequate chipset and power delivery (VRM design)

Proper cooling solution for thermal management

However, since those correct motherboard specifications are not provided in the options, A is the only viable system-level requirement relevant to stability under high-performance load.

Question: 428

Which of the following is used to implement PoE?

  1. Modem
  2. Range extender
  3. Media converter
  4. Injector

Answer: D

Explanation:

The correct answer is D. Injector.

Power over Ethernet (PoE) allows network cables to carry electrical power to devices such as wireless access points, IP cameras, and VoIP phones, eliminating the need for separate power supplies. According to the CompTIA A+ Core 1 220-1201 objectives under Networking, PoE can be implemented in the following ways:

PoE-enabled switches: Switches that can supply power directly over the Ethernet ports.

PoE injectors: Devices that add power to an existing Ethernet connection when the switch or router does not provide PoE.

Why the other options are incorrect:

A . Modem: A modem connects a network to the Internet but does not provide PoE functionality.

B . Range extender: Extends the range of a wireless network; does not supply power over Ethernet.

C . Media converter: Converts one type of network media to another (e.g., fiber to copper) but does not implement PoE.

Therefore, when a switch does not natively provide PoE, a PoE injector is the standard solution to add power to the Ethernet line.

Question: 429

After a data breach, an affected file server is reimaged and must have the data restored. The server array is configured as RAID 6. The technician restoring the data notices that the data transfer is sluggish and restarts the server. After restarting the server, the technician continues the restore process and sees one red LED in the drive array. Which of the following should the technician do next to remediate the issue?

  1. Reconfigure the RAID array
  2. Run a S.M.A.R.T. test
  3. Reinstall the controller drivers
  4. Replace the failed drive

Answer: D

Explanation:

The correct answer is D. Replace the failed drive.

RAID 6 is a redundant array of independent disks that can tolerate up to two drive failures while still maintaining data integrity. According to CompTIA A+ Core 1 (220-1201) objectives, a red LED on a drive in a RAID array indicates that the drive has failed or is in a critical state.

Next Step: In RAID 6, a single failed drive should be replaced immediately to prevent additional failures and maintain redundancy. The array can continue to operate in a degraded state, but performance may be slow during rebuilds. Replacing the failed drive allows the RAID controller to rebuild data onto the new drive, restoring full redundancy.

Why the other options are incorrect:

A . Reconfigure the RAID array: This would erase existing data; unnecessary if only one drive failed.

B . Run a S.M.A.R.T. test: While useful for diagnosing drive health, the red LED already indicates failure, so immediate replacement is required.

C . Reinstall the controller drivers: This does not address a physically failed drive and would not fix the degraded RAID array.

Question: 430

When a customer tries to connect a projector to a laptop in a conference room, the customer is only able to see part of the laptop’s screen projected onto the wall. Which of the following should a technician do first to troubleshoot this issue?

  1. Extend the desktop
  2. Change the resolution
  3. Mirror the desktop
  4. Switch the input source

Answer: B

Explanation:

The correct answer is B. Change the resolution.

According to the CompTIA A+ Core 1 220-1201 objectives, troubleshooting display issues involves checking the display settings, including resolution, scaling, and orientation. When a projector is only showing part of a laptop screen:

The most common cause is that the laptop’s output resolution does not match the projector’s native resolution. If the laptop is set to a resolution larger than what the projector supports, only a portion of the screen is visible.

The technician should first adjust the laptop’s resolution to match the projector’s native resolution before attempting other options like extending or mirroring the desktop.

Why the other options are incorrect:

A . Extend the desktop: This is only used if the user wants to have two separate screens (dual monitors), not to fix partial display issues.

C . Mirror the desktop: Mirroring duplicates the laptop display but does not solve issues caused by resolution mismatch.

D . Switch the input source: Necessary only if the projector is on the wrong input, but the problem here is a partial display, not no display.

Why the other options are incorrect:

A . Reattach the heat sinks: Heat sinks are part of the CPU/GPU cooling assembly and are unrelated to replacing the display.

C . Install a new CPU fan: CPU fans are part of the cooling system, not the display assembly.

D . Reset the BIOS to default settings: Not required for physically replacing the display; the BIOS retains settings independently of display hardware.

Question: 456

Employees report that a shared laser printer has difficulty printing on thick paper. A technician verifies that the printer works as expected on standard paper, but output on thick paper is easily smudged when touched. Which of the following should the technician do first?

  1. Install a maintenance kit
  2. Change the fuser temperature
  3. Clean the transfer roller
  4. Install an OEM toner cartridge

Answer: B

Explanation:

The correct answer is B. Change the fuser temperature.

A laser printer fuses toner onto paper using heat and pressure. Thicker paper often requires a higher fuser temperature to properly adhere the toner.

If the output smudges on thick paper but prints fine on standard paper, adjusting the fuser temperature is the first step before performing more invasive maintenance or replacing parts.

Why the other options are incorrect:

A . Install a maintenance kit: Typically includes rollers, belts, and other parts; this is not the first action if the issue is temperature-related.

C . Clean the transfer roller: Cleaning may improve print quality, but smudging on thick paper usually relates to insufficient fusing heat.

D . Install an OEM toner cartridge: The issue is unlikely to be caused by non-OEM toner if standard paper prints correctly.

  1. SAN
  2. PAN
  3. MAN
  4. WLAN

Answer: D

Explanation:

The correct answer is D. WLAN (Wireless Local Area Network).

A WLAN is a wireless network that covers a limited area such as an office, building, or campus.

Using a heat map helps administrators determine optimal placement of access points, identify areas of weak signal, and plan coverage for employees’ devices.

Why the other options are incorrect:

A . SAN (Storage Area Network): Connects storage devices over a network; not used for wireless coverage.

B . PAN (Personal Area Network): Covers a very small area, such as a single person’s devices (Bluetooth, USB, etc.), not a whole office.

C . MAN (Metropolitan Area Network): Covers a city or large geographic area; too large for a floor plan.

Question: 459

Which of the following describes an advantage of mini-LED displays over OLED displays?

  1. Increased contrast
  2. No backlight
  3. Improved viewing angle
  4. Decreased burn-in

Answer: D

Explanation:

The correct answer is D. Decreased burn-in.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.

Unlike OLED displays, which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.

Why the other options are incorrect:

A . Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.

B . No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.

C . Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.

Question: 460

Answer: A

Explanation:

The correct answer is A. Loopback plug. A loopback plug is used to test a network interface card (NIC) port by sending a signal out of the port and back into the same port, verifying that the NIC can send and receive data properly.

This is a common diagnostic tool when troubleshooting network connectivity issues on individual devices.

Why the other options are incorrect:

B . Toner probe: Used for tracing and locating cables, not for testing NIC ports.

C . Cable tester: Checks the integrity of network cables but does not verify NIC send/receive functionality.

D . Network tap: Passively monitors network traffic but does not test the NIC port itself.

Question: 461

A user is trying to present a video in a conference room. The video appears when the user connects the computer to the TV display with an HDMI cable. However, there is no sound coming through. The computer and TV volumes are at 50%. Which of the following should the user perform next?

  1. Adjust the volume settings
  2. Swap the HDMI cable
  3. Reinsert the HDMI cable
  4. Verify the audio output assignment

Answer: D

Explanation:

The correct answer is D. Verify the audio output assignment.

HDMI carries both video and audio signals. If video displays correctly but audio is not heard, it is often because the computer is still outputting sound to its internal speakers rather than the HDMI connected device.

The user should check the audio output settings in the operating system and ensure the HDMI device (TV or projector) is selected as the audio output device.

Why the other options are incorrect:

A . Adjust the volume settings: Volumes are already at 50%, so adjusting them will not solve the problem if the audio output is assigned incorrectly.

B . Swap the HDMI cable: The video is working fine, so the cable is likely functional.

C . Reinsert the HDMI cable: Unlikely to resolve audio assignment issues if the connection is already

Question: 462
