CompTIA 220-1101 Online Questions & Answers

• Question 81:

  A technician builds a custom computer for a customer, installing a high-end video card that draws 550W at maximum load. After a day of using the computer, the customer notices video loss and a burning smell.

  Which of the following should the technician troubleshoot first?

  A. Video card seating in the PCIe slot
  B. RAM overclock configuration in the BIOS
  C. ATX 3.0 16-pin connector
  D. Chassis fan-speed settings
  C. ATX 3.0 16-pin connector

  ---

  Explanation

  The ATX 3.0 16-pin connector provides power to high-end graphics cards, and a poor connection could lead to power issues and burning smells.

• Question 82:

  A user is traveling to another country and will be unable to get personal cell phone service after the plane lands. Which of the following should the user update to resolve the issue?

  A. CDMA
  B. PRL
  C. MDM
  D. GPS
  B. PRL

  ---

  Explanation

  Updating the preferred roaming list (PRL) is what a user should do to resolve the issue of being unable to get personal cell phone service after traveling to another country. The PRL is a database that contains information about cell towers and frequencies that a phone can use in different areas. Updating the PRL can improve the phone's ability to connect to local networks and avoid roaming charges. CDMA is a type of cellular technology that uses code division multiple access to transmit data over radio frequencies. MDM is an acronym for mobile device management, which is a type of software solution that allows remote management and security of mobile devices. GPS is an acronym for global positioning system, which is a satellite-based navigation system that provides location and time information

• Question 83:

  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
  A. Cat 5

  ---

  Explanation

  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.

• Question 89:

  A user reports a workstation is having the following issues:

  1.OS performance is slow

  2.The workstation turns off randomly from time to time

  3.The fans are running loudly

  Which of the following is most likely the cause?

  A. The system is infected with malware.
  B. The CPU is overheating.
  C. The hard drive is failing.
  D. The power supply is insufficient.
  B. The CPU is overheating.

  ---

  Explanation

  One of the possible causes of slow OS performance, random shutdowns, and loud fan noise is the CPU overheating. This can happen due to dust accumulation, faulty cooling system, or high CPU usage. Overheating can damage the CPU

  and other components, so it is important to monitor the CPU temperature and take preventive measures.

• Question 90:

  A company is testing the latest model of a laptop. After turning on the laptop, there is a noticeable burning smell.

  Which of the following steps should a technician take to troubleshoot the laptop issue? (Select two).

  A. Turn it off and disconnect all power sources.
  B. Submit an emergency request to the local facilities manager.
  C. Check for foreign objects, liquid spills, and internal damage.
  D. Contact the vendor and submit a return request.
  E. Remove the device from the MDM.
  F. Try an alternate AC adapter.
  A. Turn it off and disconnect all power sources.
  C. Check for foreign objects, liquid spills, and internal damage.

  ---

  Explanation

  Turning off the laptop and disconnecting power immediately prevents further damage and potential safety hazards. Checking for foreign objects or damage is essential for identifying the root cause. Other options, such as contacting the vendor or using a different adapter, are not immediate troubleshooting steps for an active burning smell. CompTIA A+ Core 1 objectives emphasize safety and hardware troubleshooting.
