CompTIA 220-1201 Online Questions & Answers

• Question 441:

  A user reports that they cannot get their laptop to work with a video projector connected with an HDMI cable. The projector is turned on. The HDMI cable is securely connected on both ends, and the laptop displays properly on its own screen.

  The display mode is set to "Duplicate" on the laptop.

  Which of the following is most likely causing the issue?

  A. The projector does not support HDMI connections.
  B. The laptop display mode should be set to "Extend".
  C. An HDMI port on the projector failed.
  D. The input source is incorrect on the projector.
  D. The input source is incorrect on the projector.

  ---

  Explanation

  Comprehensive and Detailed Explanation

  CompTIA troubleshooting procedures emphasize confirming input source settings on the external display device.

  Even if the HDMI cable is connected properly:

  The projector must be set to the correct input source (HDMI 1, HDMI 2, etc.).

  If the source is incorrect, the laptop will not display, even though the laptop output is functioning normally.

  Since the projector is powered on, and the laptop is already set to "Duplicate," and cables are good, the most likely cause is:

  # The projector is set to the wrong input source.

  This is a common real-world issue covered under "video and projector troubleshooting."

  Why the other answers are incorrect

  A. Projector may support HDMI; this is not the "most likely."

  B. "Extend" is not required -- "Duplicate" works for projectors.

  C. A failed HDMI port is possible but not the most likely scenario. Final Answer: D

• Question 442:

  A laptop is experiencing slow performance writing data.

  Which of the following is the best component for a technician to upgrade to fix the issue?

  A. RAM
  B. HDD
  C. TPM
  D. CPU
  B. HDD

  ---

  Explanation

  The best component for a technician to upgrade to fix the issue of slow performance writing data is B. HDD. HDD stands for hard disk drive, which is a type of storage device that uses physical disks to store data. HDDs have moving parts that can slow down the read and write operations, especially when the data is fragmented or the disk is full 12. A better alternative to HDDs is SSDs, which stands for solid state drives. SSDs use flash memory and do not have any moving parts.

  SSDs can read and write data faster and use less power, which can improve the performance and battery life of the laptop 13. Upgrading to an SSD can provide a significant improvement in performance 2. The other components are not as relevant or effective as upgrading the HDD. RAM stands for random access memory, which is a type of memory that stores temporary data for the CPU to process. RAM can affect the overall speed of the laptop, but it does not directly affect the writing performance of the storage device 1. TPM stands for trusted platform module, which is a security chip that encrypts and protects data on the laptop. TPM does not affect the performance of the laptop, but rather its security 1. CPU stands for central processing unit, which is the main processor of the laptop that executes instructions and calculations. CPU can affect the performance of the laptop, but it is not as easy or cost-effective to upgrade as the HDD1.

• Question 443:

  Which of the following allows a switch to be divided into separate logical networks?

  A. VLAN
  B. SSL VPN
  C. NAT
  D. RADIUS
  A. VLAN

  ---

  Explanation

  A Virtual LAN (VLAN) is a network topology that allows a switch to be divided into separate logical networks. This allows for the creation of multiple broadcast domains within a single physical network, improving network segmentation and security. With VLANs, you can segment your network so that different departments, applications, or users are isolated from each other, improving network security and performance.

• Question 444:

  A company deploys its infrastructure in self-operated data centers. The company recently migrated some of its applications to a public cloud.

  Which of the following most accurately describes the cloud model the company is following?

  A. Public
  B. Hybrid
  C. Community
  D. Private
  B. Hybrid

  ---

  Explanation

  A hybrid cloud combines private infrastructure (on-premises, self-operated data centers) with public cloud services, providing flexibility and scalability.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 -Cloud concepts: "A hybrid cloud model integrates private and public cloud infrastructure to allow applications and data to be shared between them."

• Question 445:

  A technician needs to move a workstation to a different logical network segment.

  Which of the following technologies should the technician use?

  A. DHCP
  B. VLAN
  C. DNS
  D. VPN
  B. VLAN

  ---

  Explanation

  AVLAN (Virtual LAN)is used to logically segment a network without requiring physical separation. It enables grouping devices based on function or department regardless of their physical location.

  Option A (DHCP):Assigns IP addresses dynamically but doesn't create network segments.

  Option C (DNS):Resolves domain names to IP addresses, not used for network segmentation.

  Option D (VPN):Provides secure remote access but does not relate to logical segmentation within a local network.

• Question 446:

  A Wi-Fi router is set up in a central room. A user on the outer edge of the building reports slow connections and intermittent internet drops.

  Which of the following actions will solve the issue?

  A. Enabling the 5GHz band
  B. Running the flushdns command
  C. Upgrading the laptop to a Wi-Fi 6 NIC
  D. Installing additional wireless APs around the location
  D. Installing additional wireless APs around the location

  ---

  Explanation

  CompTIA A+ explains that Wi-Fi issues at the edges of a building are typically caused by weak signal coverage, not client configuration. The recommended solution is to add additional wireless access points (APs) or mesh extenders to expand coverage and eliminate dead zones.

  Enabling 5GHz would worsen the problem because 5GHz has shorter range and penetrates walls less effectively than 2.4GHz. Flushing DNS affects name resolution, not wireless signal strength. Upgrading the NIC to Wi-Fi 6 improves maximum throughput but still depends on sufficient signal, which the user does not have.

  Additional APs ensure strong signal-to-noise ratio, consistent throughput, and stable roaming all solutions emphasized in the A+ wireless troubleshooting section. Therefore, option D is the correct and CompTIA-aligned fix.

• Question 447:

  A customer reports that a text-only document prints with unrecognizable characters. The print preview correctly displays the document.

  Which of the following is the most likely cause of the issue?

  A. Outdated firmware
  B. Incorrect driver
  C. Bad toner cartridge
  D. Corrupted document file
  B. Incorrect driver

• Question 448:

  A user ran out of USB ports on their laptop but wants to plug in more devices.

  What technology is best?

  A. Near-field communication
  B. Bluetooth
  C. USB receiver
  D. Port replicator
  D. Port replicator

  ---

  Explanation

  A port replicator expands the number and types of ports available to a laptop, including additional USB ports, video outputs, Ethernet, and more. CompTIA A+ identifies port replicators as solutions for users needing greater connectivity, especially when docking stations are unnecessary or unavailable.

  Port replicators connect through a single USB or proprietary connector and provide multiple expansion ports instantly. This resolves the issue of limited USB availability without requiring hardware replacement.

  NFC (A) is used for short-range communication, not peripheral connectivity. Bluetooth (B) only supports wireless peripherals such as mice and headphones, not wired USB devices. A USB receiver (C) adds wireless capability for one specific device, not general expansion.

  Thus, the correct solution is a port replicator.

• Question 449:

  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.

  INSTRUCTIONS

  Based on the customer's requirements, connect the customer's devices to the proper outlets. Select the power source for the Surge Protector and UPS. This may require reselecting dropdowns or removing tokens.

• Question 450:

  A technician is troubleshooting an unresponsive touchscreen on a smartphone. The technician performs a hard reset, but the touchscreen remains unresponsive.

  Which of the following is the MOST likely cause of the issue?

  A. Missing drivers
  B. Virus infection
  C. Low battery
  D. Damaged digitizer
  D. Damaged digitizer

  ---

  Explanation

  The digitizer is a crucial component of a touchscreen device, responsible for translating touch actions into digital signals that the device can interpret. If a hard reset does not resolve the touchscreen's unresponsiveness, it is likely that the digitizer is damaged. Physical damage, such as cracks or heavy impacts, can impair the digitizer's ability to function correctly, leading to an unresponsive touchscreen. This type of hardware issue requires professional repair or replacement of the touchscreen assembly to restore functionality.
