The DNS record that points to a host's name server is:

• A. A
• B. MX
• C. SRV
• D. NS

Answer: (D)

NS records identify which servers are authoritative for a domain. This record type points to the hostnames of the DNS servers that hold the domain’s zone data, effectively directing resolvers to where queries for that domain should be answered. The NS record itself names the name servers; those servers may have A or AAAA records to map their names to IPs. Other DNS records serve different purposes—A maps a hostname to an IP address, MX designates mail servers, and SRV provides service location details like port numbers. So, the record that points to a host’s name server is the NS record.
