Which of the following should a technician use in DNS to map a device to an IPv6 address?
Correct Answer: C
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.
