CompTIA 220-1101 Online Questions & Answers

• Question 221:

  Which of the following allows all VMs in a virtual environment to have RAM allocated for use?

  A. Measured service
  B. Containerization
  C. Synchronization
  D. Resource pooling
  D. Resource pooling

  ---

  Explanation

  The concept described in the question is related to virtualization and resource management in a virtual environment. The approach that allows all virtual machines (VMs) to have memory (RAM) allocated for use is known as resource pooling. Therefore, the correct answer is D: "Resource pooling." This approach allows resources to be allocated dynamically to VMs based on their current needs, and ensures that resources are used efficiently in the virtual environment. Resource pooling is a technique used in virtualization to share resources among multiple virtual machines (VMs). With resource pooling, RAM can be allocated dynamically to VMs as needed, allowing all VMs in a virtual environment to have RAM allocated for use.

• Question 222:

  Which of the following is the purpose of an IPv4 gateway?

  A. To distribute IP addresses
  B. To generate ARP traffic
  C. To assign APIPA addresses
  D. To route traffic to the next network
  D. To route traffic to the next network

  ---

  Explanation

  To route traffic to the next network. An IPv4 gateway is a device that connects two or more networks and forwards packets based on their destination IP addresses. It acts as an intermediary between a host and the rest of the internet,

  allowing communication across different networks. A gateway does not distribute IP addresses, generate ARP traffic, or assign APIPA addresses, as these are functions of other network components.

• Question 224:

  A technician needs to troubleshoot a user's smartphone that will not connect to its wireless provider's service. Which of the following should the technician check first?

  A. SIM card
  B. Network settings
  C. Subscription plan
  D. Bluetooth connection
  C. Subscription plan

• Question 225:

  A user is unable to plug a USB 3.0 device into a USB port. Upon inspection, a technician notices the USB 3.0 port appears to be shallower than the other USB ports, preventing a solid connection. Which of the following is the most likely cause?

  A. A foreign object Is stuck Inside the port
  B. The cable connection utilized the wrong orientation.
  C. The USB cable is physically damaged.
  D. The USB port belongs to a different form factor.
  A. A foreign object Is stuck Inside the port

• Question 226:

  A user's laptop is making a loud clicking noise, and the battery life is shorter than expected. Which of the following storage options would a technician MOST likely install to address the user's issues?

  A. MicroSD
  B. 15,000rpm HDD
  C. SAS SSD
  D. SATA SSD
  B. 15,000rpm HDD

  Explanation

• Question 227:

  A technician is troubleshooting poor printing quality on an inkjet printer. The pages have white lines running through the text and graphics. Which of the following is the most likely cause?

  A. Worn out rollers
  B. Clogged printhead
  C. Faulty ink cartridges
  D. Poor quality paper
  B. Clogged printhead

  ---

  Explanation

  When the printhead is clogged, it can result in incomplete or inconsistent ink deposition on the paper, leading to white lines in the printed output. Cleaning the printhead or performing a printhead alignment can often resolve this issue.

• Question 228:

  A user is having trouble accessing files on the network. A technician suspects the issue is a result of a failed NIC_ Which of the following steps should the technician take to troubleshoot this issue?

  A. Document key findings, actions, and outcomes
  B. Establish a theory of probable cause.
  C. Test the theory to determine the cause_
  D. Identify the problem and act
  E. Verity system functionality
  C. Test the theory to determine the cause_

  ---

  Explanation

  The answer is

  C. Test the theory to determine the cause.

  According to the CompTIA A+ troubleshooting methodology, the steps to troubleshoot any problem are: Identify the problem and act Establish a theory of probable cause Test the theory to determine the cause Establish a plan of action to resolve the problem and implement the solution Verify system functionality and implement preventive measures Document key findings, actions, and outcomes In this scenario, the technician has already identified the problem (trouble accessing files on the network) and established a theory of probable cause (a failed NIC). The next step is to test the theory to determine the cause, which involves verifying whether the NIC is working properly or not. Some possible ways to test the theory are: Check the physical connection and status of the NIC port and cable12 Check the link state and speed of the NIC using ethtool or ip commands2 Check the configuration and state of the NIC using nmcli, teamdctl, or teamnl commands2 Check the driver and firmware of the NIC using lspci, modinfo, or dmesg commands2 Check the logs for any errors or warnings related to the NIC using journalctl or grep commands2 Uninstall and reinstall the NIC driver using Device Manager or modprobe commands13 Replace the NIC or cable with a known good one and test again13 If any of these tests confirm that the NIC is faulty, then the technician can proceed with the next step of establishing a plan of action to resolve the problem and implement the solution. If none of these tests reveal any issues with the NIC, then the technician can eliminate it as a probable cause and look for other possible causes. Therefore, option C is the correct answer.

• Question 229:

  Every time a user submits a print job, the user receives an error from the printer requesting A4 paper. No other users in the office are having printing issues.

  Which of the following is the best way to address the user's issue?

  A. Reinstall the printer driver on the user's computer.
  B. Print to a different printer in the office.
  C. Set the printer defaults in the Control Panel to print to letter-sized paper.
  D. Have the user check the page size on every print job.
  C. Set the printer defaults in the Control Panel to print to letter-sized paper.

  ---

  Explanation

  If a user consistently receives an error requesting A4 paper for print jobs, and this issue is isolated to a single user, it's likely that the user's printer settings are configured incorrectly for A4 paper size instead of the standard letter size used in the office. Adjusting the printer defaults in the Control Panel on the user's computer to use letter-sized paper should resolve the issue without needing to reinstall drivers, switch printers, or require the user to check page size for every job.

• Question 230:

  A technician is upgrading memory on a laptop that is experiencing performance issues. Which of the following RAM types should most likely be specified for installation?

  A. ECCDIMMDDR5
  B. High latency DDR5
  C. Registered DIMM DDR5
  D. SODIMM DDR5
  D. SODIMM DDR5

  ---

  Explanation

  For laptops, the most common type of RAM used is Small Outline Dual Inline Memory Module (SODIMM) due to its smaller size compared to DIMMs used in desktops. DDR5 is the latest generation of RAM, offering higher speed and efficiency. ECC (Error- Correcting Code) DIMM DDR5 and Registered DIMM DDR5 are typically used in servers and high-end workstations for error correction and stability, not in standard laptops. High latency DDR5 is not a desirable specification for RAM as lower latency is preferred for faster performance.
