A

Answers

A

B.

CNAME

Answers
B.

CNAME

C.

AAAA

Answers
C.

AAAA

D.

MX

Answers
D.

MX

Suggested answer: C

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.

C . AAAA: This record is used to associate a hostname with an IPv6 address in DNS.

Why the other options are incorrect:

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

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

D . 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.
