I am going with D for sure and possibly C also. The question wasn't real clear to me.

It's gotta be D. The A (host) record is for the forward lookup zone, and the PTR (Pointer) record is for the reverse lookup zone. The cover each other's back, so to speak.

Just re-read DNS guide, I think it's PTR, because it says it actually point to the domain.

The answer would be D. The question states that you update a host resource record so the only other option would be updating the pointer record.

And the answer is .....

Correct Answers: D

An A resource record is often referred to as a host resource record. When updating a host resource record, there is a possibility that there is an associated PTR resource record that points to the same data, only in the opposite direction of the A record.

When updating a host record, you can check the Update Associated Pointer (PTR) record checkbox. This enables the update to be dynamic.

A Start of Authority (SOA) resource record is at the beginning of every zone.
A Name Server (NS) resource record indicates that a server is responsible for the zone.
An Address (A) record is used to map any computer's FQDN to an IP address.
A Pointer (PTR) resource record does just the opposite of an A record - it maps an IP address to a FQDN.
The Canonical Name (CNAME) resource record creates an alias for a computer.
A Mail Exchange (MX) record specifies that the computer is a mail exchange server for the domain.
Service (SRV) resource records allow you to specify a location of a server that provides a specific service.
