A network administrator needs to change where the outside DNS records are hosted. Which of the following records should the administrator change the registrar to accomplish this task?
Correct Answer: A
To change where the outside DNS records are hosted, the network administrator needs to update the NS (Name Server) records at the domain registrar. NS records specify the authoritative name servers for a domain, directing where DNS queries should be sent.
* NS (Name Server) Records: These records indicate the servers that are authoritative for a domain.
Changing the NS records at the registrar points DNS resolution to the new hosting provider.
* SOA (Start of Authority): Contains administrative information about the domain, including the primary name server.
* PTR (Pointer) Records: Used for reverse DNS lookups, mapping IP addresses to domain names.
* CNAME (Canonical Name) Records: Used to alias one domain name to another, not relevant for changing DNS hosting.
