Networking Fundamentals — Question 81

Which DNS record type specifies the host that is the authority for a given domain?

Answer options

• A. NS
• B. MX
• C. CNAME
• D. SOA

Correct answer: D

Explanation

The correct answer is SOA (Start of Authority), which defines the primary name server for the domain and provides essential information about the domain's settings. NS (Name Server) records indicate which servers are authoritative but do not provide the detailed configuration like SOA. MX (Mail Exchange) records are used for email routing, while CNAME (Canonical Name) records create aliases for other domain names.
