CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 441:

  A technician replaced a motherboard on a server, and now the 64-bit hypervisor is not loading correctly. Which of the following needs to be enabled for the hypervisor to run?

  A. Hardware prefetcher

  B. Hyperthreading

  C. vPro

  D. VT-d

  Correct Answer: D

  https://techlibrary.hpe.com/docs/iss/proliant-gen10-uefi/s_enabling_VT- d.html Enabling VT-d (Virtualization Technology for Directed I/O) in the server's BIOS settings is required for the hypervisor to run properly. References: CompTIA A+ Certification uide, Ninth Edition, Chapter 11

• Question 442:

  A user brings an older laptop to the help desk and reports issues with the keyboard. Upon inspection, the technician does not see any external damage but notices that many keystrokes da not register in a word processor. The laptop works fine when the technician tests it with an external keyboard. Which of the following actions would MOST likely resolve the issue?

  A. Disable the sticky keys feature.

  B. Clean the keyboard.

  C. Reset the BIOS settings to default.

  D. Charge the laptop.

  Correct Answer: B

  B. Clean the keyboard. In this scenario, the laptop works fine when the technician tests it with an external keyboard, but many keystrokes do not register in a word processor when the internal keyboard is used. This suggests that the issue may be related to the internal keyboard and not the software or hardware settings. Cleaning the keyboard is a simple and effective solution to address common issues such as dirt, debris, or stuck keys that can prevent the keyboard from functioning correctly.

  Disabling the sticky keys feature will not likely resolve the issue, as it is designed to assist users who have difficulty pressing multiple keys simultaneously.

  Resetting the BIOS settings to default may resolve certain hardware or software issues, but it is unlikely to address an issue with a physical component such as the keyboard.

  Charging the laptop may resolve some performance issues that are related to a low battery, but it is not likely to resolve an issue with the keyboard.

• Question 443:

  A technician is commissioning a workstation that is required to have mirrored storage, utilizing two 4TB drives that support one failure. Which of the following BEST meets these requirements?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 10

  Correct Answer: B

  RAID 1 is a mirrored configuration that utilizes two drives and provides redundancy by allowing one drive to fail without data loss. This configuration meets the requirement of mirrored storage with two 4TB drives that support one failure.

• Question 444:

  Which of the following standards supports MIMO technology?

  A. 802.11a

  B. 802.11b

  C. 802.11g

  D. 802.11n

  Correct Answer: D

  The 802.11n wireless networking standard supports Multiple Input Multiple Output (MIMO) technology. MIMO technology uses multiple antennas on both the transmitting and receiving devices to improve wireless performance by increasing the amount of data that can be transmitted simultaneously. 802.11a, 802.11b, and 802.11g do not support MIMO technology.

• Question 445:

  A small office has a wireless network with several access points for roaming laptop use. Users occasionally report that the wireless connection drops or becomes very slow. Users have confirmed that this issue only happens when connected to the office wireless network. Which of the following would MOST likely be the cause?

  A. Hidden SSID

  B. Device interference

  C. Ethernet port flapping

  D. High ISP latency

  Correct Answer: B

  Device interference is the most likely cause of the wireless connection dropping or becoming slow. Interference can come from other wireless devices, microwave ovens, or physical barriers like walls and metal objects. Hidden SSID, Ethernet port flapping, and high ISP latency are not likely to cause this issue. Wireless interference from other devices can cause a drop in wireless connection speed and stability. In a small office environment, there may be several wireless devices competing for the same bandwidth, causing the issues described.

• Question 446:

  A company just bought a printer capable of automatically printing on both sides of the paper After installation, however, the technician can only print on both sides of the paper manually. Which of the following should the technician do to fix the issue?

  A. Install the most recent firmware upgrade available for the printer.

  B. Contact the vendor for a hardware replacement.

  C. Reinstall the printer software and drivers, and then restart the printer.

  D. Read the installation manual and configure duplex settings.

  Correct Answer: D

  The issue described in the question is most likely due to an incorrect configuration of the printer's duplex settings. To enable automatic duplex printing, the technician needs to read the printer's installation manual to understand how to configure the printer's duplex settings correctly. Once the settings are configured, the printer should be able to print on both sides of the paper automatically. To fix the issue of a newly installed printer capable of automatically printing on both sides of the paper but only printing on both sides manually, the technician should read the installation manual and configure duplex settings. Duplex printing settings can be configured in the printer driver software, which can be accessed through the printer settings in the Control Panel. Installing the most recent firmware upgrade available for the printer, contacting the vendor for a hardware replacement, or reinstalling the printer software and drivers and restarting the printer will not resolve the issue.
