CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 451:

  A user requested upgrades to a company-Issued laptop to increase its performance while working with a large database stored on drive C. Which of the following tasks should a systems administrator complete to BEST meet this goal? (Select TWO).

  A. Configure RAID 1.

  B. Install a hybrid drive.

  C. Upgrade to 1GB NIC.

  D. Increase the RAM.

  E. Migrate to a SSD.

  F. Upgrade the power supply.

  Correct Answer: DE

  To increase the performance of a laptop working with a large database stored on drive C, a systems administrator should increase the RAM and migrate to an SSD. Increasing the RAM will help the laptop to better handle the large database,

  while migrating to an SSD will improve the speed at which the laptop can access the database. Configuring RAID 1, installing a hybrid drive, upgrading to a 1GB NIC, and upgrading the power supply will not directly improve the laptop's

  performance when working with a large database.

  If a laptop has been returned for a screen repair and the owner insists the screen is broken, but occasionally a faded image is able to be seen in very bright settings on the desktop, the first step the repair technician should take is to ensure the backlight is functioning as expected. If the backlight is faulty, the screen may appear to be broken, but it may only be dim or too dark to be visible

  1.

  Identify the problem.

  Gather information from the user, identify user changes, and, if applicable, perform backups before making changes.

  Inquire regarding environmental or infrastructure changes.

  2.

  Establish a theory of probable cause (question the obvious).

  If necessary, conduct external or internal research based on symptoms.

  3.

  Test the theory to determine the cause.

  Once the theory is confirmed, determine the next steps to resolve the problem.

  If the theory is not confirmed, re-establish a new theory or escalate.

  4.

  Establish a plan of action to resolve the problem and implement the solution.

  Refer to the vendor's instructions for guidance.

  5.

  Verify full system functionality and, if applicable, implement preventive measures.

  6.

  Document the findings, actions, and outcomes.

• Question 457:

  A user on a SOHO network is unable to watch online videos, even at 240 pixels. The technician runs ipconfig from the user's computer and records the following:

  

  The technician then connects a test laptop to the router via the user's Cat 5 cable and records the following information:

  

  Which of the following is MOST likely causing the user's issue?

  A. Incorrect IP address

  B. Faulty NIC

  C. Misconfigured default gateway

  D. Bad network cable

  Correct Answer: B

  Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.

• Question 458:

  A computer that contains critical data has not been backed up and will not boot past a S A R T, error that indicates imminent hard disk failure. Which of the following actions should the technician take FIRST?

  A. Run diagnostics on the faulty hard drive using a boot disk

  B. immediately replace the hard drive generating the SMART error

  C. Turn off S M A R T, monitoring in the computer's BIOS settings

  D. Attempt to boot the operating system in safe mode

  Correct Answer: A

  The technician should run diagnostics on the faulty hard drive using a boot disk first when a computer that contains critical data has not been backed up and will not boot past a S M A R T. error that indicates imminent hard disk failure.

• Question 459:

  A user submitted a ticket to report an issue with a new printer that is no longer accepting new print jobs. The technician verifies the printer is on and notices the printer LCD screen has the following error message: Paper Jam, Jam in fuser.

  Which of the following is the MOST efficient next step the technician should complete?

  A. Apply a maintenance kit to the printer

  B. Check the printer paper path to locate any obstructions.

  C. Turn the printer on and off to see if the error clears.

  D. Replace the fuser.

  Correct Answer: B

  The MOST efficient next step the technician should complete is to check the printer paper path to locate any obstructions1. The error message "Paper Jam, Jam in fuser" indicates that there is a paper jam in the fuser2. The fuser is one of the parts of a laser printer most likely to fail without giving any explicit message2. The printer LCD screen indicates a paper jam in the fuser. The most efficient next step the technician should complete is to check the printer paper path to locate any obstructions. Applying a maintenance kit or replacing the fuser may not be necessary if the issue is caused by a paper jam.

• Question 460:

  A customer reports that a computer is never able to reach more than a 100Mbps transfer data rate, even when using a Gigabit LAN card. While troubleshooting, the technician notices the network cable needs to be replaced. Which of the following cable categories is limiting the transfer speed?

  A. Cat 5

  B. Cat 5e

  C. Cat 6 D. Cat 6a

  Correct Answer: A

  Cat 5 cable is limited to a maximum data transfer rate of 100Mbps, while Cat 5e, Cat 6, and Cat 6a cables support Gigabit Ethernet (1000Mbps) and higher speeds. Even though the LAN card is capable of Gigabit speeds, it cannot achieve that speed when using a Cat 5 cable. Upgrading to a Cat 5e or higher cable would allow the computer to achieve Gigabit speeds.
