CNAME

Sample Questions

Question 1

Which DNS record type maps a hostname to an IPv4 address?

A. An A record holding a 32-bit IPv4 address

B. An AAAA record holding an IPv6 address

C. A CNAME record pointing to another canonical name

D. An MX record naming a mail exchanger

✓ Correct Answer: A

The A record maps a hostname directly to a 32-bit IPv4 address. AAAA serves the same purpose but for 128-bit IPv6 addresses. CNAME aliases one name to another rather than to an address. MX designates the mail server responsible for a domain, not a host address.

Question 2

What is the purpose of a DNS PTR record?

A. It signs a zone for DNSSEC validation

B. It resolves an IP address back to a hostname

C. It delegates a subdomain to other name servers

D. It lists the mail servers for a domain

✓ Correct Answer: B

A PTR record provides reverse resolution, mapping an IP address to a hostname using the in-addr.arpa or ip6.arpa zones. DNSSEC signing uses RRSIG and DNSKEY records, not PTR. Delegation is handled by NS records. Mail server lists are held in MX records.
