CompTIA CompTIA A+ 220-1101 Questions & Answers

• Question 1:

  A technician needs to increase the available RAM on a virtual workstation. Which of the following should the technician do?

  A. Increase the ECC memory timings in the BIOS.

  B. Upgrade to the latest DDR5 modules.

  C. Clear the temporary files on the workstation's boot drive.

  D. Use a hypervisor to adjust the resource allocation.

  Correct Answer: D

  A hypervisor is a software layer that manages and allocates resources for virtual machines (VMs) on a physical host machine. A technician can use a hypervisor to adjust the resource allocation for a virtual workstation, such as increasing the

  amount of RAM assigned to it from the available pool of memory on the host machine. This can improve the performance and functionality of the virtual workstation without requiring any hardware changes or modifications.

• Question 2:

  A company would like to take advantage of the cost savings of cloud computing by only paying for the resources used. Which of the following will BEST address this need?

  A. Shared resources

  B. Rapid elasticity

  C. Metered utilization

  D. High availability

  Correct Answer: C

  Metered utilization is a cloud feature that allows cloud providers to charge customers based on their actual consumption of resources, such as CPU time, storage space, bandwidth, or transactions.This enables customers to pay only for the

  resources they use, rather than a fixed or flat rate, which can reduce costs and increase efficiency. Metered utilization can also provide more transparency and accountability for both cloud providers and customers, as they can track and

  monitor their resource usage and billing.

• Question 3:

  A video game developer is requesting a new desktop computer with eight sticks of memory. The developer wants the desktop computer to take advantage of all available memory bandwidth without sacrificing performance. Which of the following would be the BEST solution?

  A. Triple-channel with DDR5 ECC RAM

  B. Quad-channel with DDR4 RAM

  C. Quad-channel with DDR5 SODIMM

  D. Dual-channel with DDR4 RAM

  Correct Answer: B

  Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops. ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel.

• Question 4:

  A department sends in a ticket to report a printer is not working. The responding technician sees paper stuck to the fuser, which is much hotter than normal. The (user was just installed a few weeks ago. as indicated by the service history. Which of the following should the technician do NEXT?

  A. Disconnect the printer power for troubleshooting.

  B. Install a printer roller kit.

  C. Replace the overheating fuser.

  D. Replace the paper with thicker paper stock.

  Correct Answer: A

  The first step in troubleshooting a printer issue is to disconnect the printer power to avoid electric shock or further damage to the printer. The technician can then inspect the fuser and determine if it needs to be replaced or repaired. Installing a printer roller kit or replacing the paper with thicker paper stock will not solve the problem of the overheating fuser. Replacing the fuser without disconnecting the power is dangerous and not recommended. References: https://www.comptia.org/certifications/a#examdetails https://www.comptia.org/blog/what-is-a-fuser

• Question 5:

  A customer has a Wi-Fi-capable laptop to use when traveling for work

  Which of the following will allow the laptop to stay connected when the user travels?

  A. Cellular card

  B. Wi-Fi extender

  C. Bluetooth

  D. GPS

  Correct Answer: A

  A cellular card is a device that allows a laptop to connect to the internet using a cellular network, such as 4G or 5G. A cellular card can provide internet access when the user travels and does not have access to a Wi-Fi network. A cellular card may require a subscription plan from a cellular service provider. A Wi-Fi extender is a device that boosts the signal of an existing Wi-Fi network, but it does not provide internet access by itself. Bluetooth is a wireless technology that allows devices to communicate over short distances, but it does not provide internet access either. GPS is a satellite-based system that provides location and navigation information, but it does not provide internet access as well. References: https://www.comptia.org/blog/what-is-a-cellular-card

• Question 6:

  A business purchased a new multifunction printer that will be used to photocopy documents with hundreds of pages. A technician is configuring the printer. Which of the following features should the technician ensure is set up?

  A. SMB

  B. PCL

  C. ADF

  D. SSH

  Correct Answer: C

  Automatic document feeder (ADF) is a feature that allows a multifunction printer to photocopy documents with hundreds of pages automatically without requiring manual intervention. ADF scans multiple pages from a stack of documents and feeds them into the printer one by one. SMB is a network protocol that allows file sharing and printer access among different devices on a network. PCL is a printer language that controls how data is formatted for printing. SSH is a network protocol that allows secure remote access to another device over an encrypted connection.

• Question 7:

  An IT technician is working on a help desk ticket concerning a user's inability to create a virtual machine. The technician has already checked the RAM and HDD space in the user's machine. Which of the following settings should the technician check NEXT to help troubleshoot the issue?

  A. BitLocker

  B. MSConfig

  C. BIOS

  D. Secure Boot

  Correct Answer: C

  One of the possible settings that could prevent a user from creating a virtual machine is BIOS (Basic Input/Output System). BIOS is a firmware that controls how hardware components interact with each other and with software applications. Some BIOS settings may need to be changed or enabled to allow virtualization, such as VT-x (Intel Virtualization Technology) or AMD-V (AMD Virtualization). The other options are not related to virtualization settings. Verified References: [How To Enable Virtualization In BIOS Settings].

• Question 8:

  Which of the following components houses the MX record?

  A. DNS

  B. VLAN

  C. DHCP

  D. SMTP

  Correct Answer: A

  The MX record is housed in the DNS (Domain Name System) which is responsible for translating domain names into IP addresses and vice versa. The MX record specifies the mail server responsible for accepting email messages on behalf of a domain name and is a resource record in the DNS123.

• Question 9:

  A user reports that a computer will not turn on. The technician verifies the power cord and the outlet the computer are plugged into are both working properly. Which of the following is the hardware component that has MOST likely failed?

  A. PSU

  B. CPU

  C. RAM

  D. GPU

  Correct Answer: A

  The power supply unit (PSU) is the component that converts AC power from the outlet to DC power for the computer. If the PSU fails, the computer will not turn on. The CPU, RAM, and GPU are not directly related to the power supply and would not prevent the computer from turning on.

• Question 10:

  The GPS on a user's phone has been unreliable. Which of the following will MOST likely resolve the issue?

  A. Enabling high-accuracy mode

  B. Replacing the battery

  C. Disabling Wi-Fi connections

  D. Utilizing a third-party map application

  Correct Answer: A

  Enabling high-accuracy mode is the most likely action to resolve the issue of unreliable GPS on a user's phone. High-accuracy mode uses multiple sources of location data, such as Wi-Fi, cellular networks, and Bluetooth, to improve the accuracy and reliability of GPS. Replacing the battery, disabling Wi-Fi connections, or utilizing a third- party map application are unlikely to fix the GPS issue, as they are not directly related to the GPS function
