CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 151:

  A technician is adding one more line at the demarcation point. Which of the following tools would be MOST useful to accomplish this task?

  A. Toner

  B. Punchdown

  C. Network tap

  D. Crimper

  Correct Answer: B

  Punchdown tools are used to make connections between wires in a 66/110 block at the demarcation point. The tool is used to insert the wire into the appropriate holes in the block, and it can be used to add additional lines to the demarcation point. The other options are not the correct tools for adding lines to the demarcation point. A toner is used to identify cable pairs, a network tap is used to monitor network traffic, and a crimper is used to terminate cables.

• Question 152:

  A network technician has been tasked with creating a patch cable. The RJ45 connectors will not slay attached to the cable. Which of the following tools Is needed to fix this Issue?

  A. Cable tester

  B. Crimper

  C. Punchdown tool

  D. Loopback plug

  Correct Answer: B

  A crimper is a tool that is used to crimp (attach) an RJ45 connector onto the end of a patch cable. The crimper applies pressure to the connector to make a permanent connection between the connector and the cable, ensuring that the

  connector will stay attached to the cable.

  A cable tester is used to test the connectivity of a network cable. A punchdown tool is used to terminate network cables in a patch panel or keystone jack. A loopback plug is a diagnostic tool that is used to test network interfaces by simulating

  network traffic. Reference: CompTIA A+ Core 1 uide, page 92.

• Question 153:

  A technician set up a new access point and has noticed significant latency on the selected channel. Which of the following tools can assist with locating the BEST channel to use?

  A. Wi-Fi analyzer

  B. Netstat

  C. Net use

  D. Traceroute

  E. Network tap

  Correct Answer: A

  A Wi-Fi analyzer is a tool that can be used to scan the local area for available wireless networks and can provide information such as signal strength, interference, and available channels. It can also be used to locate the best channel to use for a given access point, which can help to reduce latency and improve performance.

• Question 154:

  A user has decided to build a new computer with parts purchased from a popular online vendor The user has referenced online resources to assemble the unit. However, when the user presses the power button, the new computer does not load the operating system's installer. Instead, the onboard speaker beeps and immediately reports an issue on the screen. Which of the following is the MOST likely issue with the new build?

  A. The user did not plug in the processor's fan.

  B. The user did not apply thermal paste to the CPU.

  C. The user did not seat the GPU correctly.

  D. The user did not install the power supply.

  Correct Answer: A

  If a computer is not booting and the onboard speaker emits beeps, it can indicate a hardware issue. One of the most common causes of beep codes is overheating, which can occur if the processor's fan is not properly installed and running. The processor's fan is responsible for cooling the processor and preventing damage to the internal components.

• Question 155:

  New memory modules were installed in several Windows desktops but some users are still reporting performance issues. Upon investigation, a systems administrator notices the desktop has not recognized the new memory modules. Which of the following should the systems administrator perform to help resolve this issue?

  A. Configure appropriate settings within the BIOS

  B. Replace the RAM

  C. Modify the boot. ini file.

  D. Install the required drivers through the Control Panel

  Correct Answer: A

  To resolve the issue of new memory modules not being recognized, the systems administrator should configure appropriate settings within the BIOS. This can include enabling memory mapping or setting memory speed and timings.

  References:

  CompTIA A+ Certification Exam Objectives, 220-1001 Section 1.8 Configure appropriate settings within the BIOS. If new memory modules were installed in several Windows desktops but some users are still reporting performance issues and

  the desktop has not recognized the new memory modules, the systems administrator should configure appropriate settings within the BIOS to help resolve this issue.

• Question 156:

  Which of the following is the SAFEST way to replace RAM on a server that has a redundant power supply?

  A. Unplug one power cable.

  B. Verify the RAM temperature.

  C. Utilize a grounding strap.

  D. Replace the RAM while the server is running.

  Correct Answer: C

  Utilizing a grounding strap is the safest way to replace RAM on a server that has a redundant power supply. This is because the grounding strap prevents electrostatic discharge (ESD) when handling the RAM, which can cause damage to the RAM and the server. Therefore, it is important to always use a grounding strap when handling RAM or other sensitive components.

• Question 157:

  A technician is working on a critical warehouse machine that will not turn on. The technician has determined the power supply for the machine failed. The warehouse manager is looking for a solution that will prevent downtime in the future. Which of the following devices should the technician install to meet this requirement?

  A. Grounded power supply

  B. Modular power supply

  C. 220V power supply

  D. Redundant power supply

  Correct Answer: D

  A redundant power supply is a device that provides two or more power supplies connected in parallel so that when one fails, the other one will take over to ensure continuous power. This is ideal for critical warehouse machines that require a reliable power source and are at risk of downtime in the event of a power failure. Installing a redundant power supply will help to reduce the chances of an unexpected power outage and keep the machine running.

• Question 158:

  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 slightly smaller than the other connections. 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.

  Correct Answer: D

  USB 3.0 ports are slightly smaller than other USB connections, so if the port appears to be the wrong size, it is likely that the port belongs to a different form factor. This can be caused by a number of factors, such as the device being too old to support USB 3.0, or the device not having a USB 3.0 port in the first place.

• Question 159:

  A technician just finished assembling a new PC for a client. Upon POST, the device presents an unspecified beep code and turns off automatically after five seconds. The technician double-checks the bill of materials for the new build and confirms all items have been installed. Which of the following should the technician do NEXT?

  A. Ensure thermal paste is being used on the CPU.

  B. Check to make sure that any video cards have auxiliary power cabling connected.

  C. Verify the header panel connector is properly connected.

  D. Spot-check that the I/O shield for the motherboard is properly installed.

  Correct Answer: C

  The technician should verify the header panel connector is properly connected. A beep code is a diagnostic tool used by motherboards to indicate issues with hardware components. This beep code may be indicating an issue with the connection between the motherboard and the case's header panel connector. This connector is responsible for providing power to the system and any connected peripherals. Therefore, the technician should verify the connection is secure and properly connected before attempting any other troubleshooting steps.

• Question 160:

  A user's touch-screen tablet is having an issue with the screen orientation. Which of the following is MOST likely causing this issue?

  A. The screen rotation is locked

  B. The screen protector on the tablet is damaged

  C. The touch-screen digitizer is malfunctioning

  D. The inverter is misconfigured

  Correct Answer: A

  The screen rotation is locked. If a user's touch-screen tablet is having an issue with screen orientation, it could be due to screen rotation being locked in device settings.

  If the screen rotation is locked, the touch-screen tablet will not rotate the screen when the device is turned. This can usually be unlocked in the settings or by pressing a specific key combination.
