CompTIA 220-1101 Online Questions & Answers

• Question 271:

  Which of the following should a technician use in DNS to map a device to an IPv6 address?

  A. A
  B. CNAME
  C. AAAA
  D. MX
  C. AAAA

  ---

  Explanation

  In DNS (Domain Name System), the AAAA record is used to map a domain or device to an IPv6 address. IPv6 addresses are 128-bit addresses, and the AAAA record is specifically designed for handling these larger addresses. AAAA: This record is used to associate a hostname with an IPv6 address in DNS.

  Why the other options are incorrect:

  A: An A record maps a domain to an IPv4 address, not an IPv6 address.

  CNAME: A CNAME (Canonical Name) record is used to alias one domain name to another but does not map to an IP address directly.

  MX: An MX (Mail Exchange) record is used to direct email traffic to the correct email servers, not to map devices to IP addresses.

  This falls under the Networking domain of the CompTIA A+ Core 1 exam.

• Question 272:

  A company wants to save printing costs by restricting network printer use. The company implements a solution that requires employees to authenticate to the printer to release print jobs.

  Which of the following has the company implemented?

  A. Access control list
  B. Audit logging
  C. Badging
  D. Print server
  C. Badging

  ---

  Explanation

  Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

  Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

  Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

  Why Not D (Print server): A print server manages print jobs but doesn't enforce authentication.

  Core 2 (220-1102), Section 2.5, authentication mechanisms.

• Question 275:

  A technician made several upgrades to a computer and then determined the power supplied by the PSU is insufficient. Which of the following would MOST likely cause the insufficiency? (Select TWO).

  A. Replacing the HDD with an SSD
  B. Upgrading the firmware

  ---

  Explanation

  The amount of RAM has little or no effect on power consumption of PC components - using between 2W - 5.5W. The power consumption for a SATA DVD drive is 15W-27W, for a SATA Blue-Ray Drive is 25W-30W.

• Question 276:

  A technician is upgrading a faulty motherboard that was ordered by an end user for an old, high-end desktop computer. However, the technician is unable to install the CPU into the socket. Upon closer inspection, the technician notices the pins on the CPU do not line up with the socket.

  Which of the following would be the best course of action for the technician to take NEXT?

  A. Try to set as many pins as possible.
  B. Install an adaptor to create a universal socket.
  C. Verify the socket type and manufacturer.
  D. Find a compatible motherboard for the CPU.
  C. Verify the socket type and manufacturer.

  ---

  Explanation

  In this situation, the best course of action for the technician to take NEXT would be

  C. Verify the socket type and manufacturer. If the pins on the CPU do not line up with the socket on the motherboard, it is likely that there is a compatibility issue between the two components. The technician should verify that the socket type and manufacturer of the motherboard match those of the CPU to ensure that they are compatible.
