Q6. Which DNS record type is used to specify the location of services for a domain?

A. Address (A)

B. Canonical name (CNAME)

C. Service (SRV)

D. Name server (NS)

Correct Answer: C. Service (SRV)

Explanation:

The Service (SRV) record is used to specify the location of services for a domain, such as SIP or LDAP servers. The Address (A) record maps a domain name to an IP address, while the Canonical name (CNAME) record creates an alias for a domain name. The Name server (NS) record specifies the authoritative DNS server for a particular domain.
