CompTIA Network+ (N10-009) — Question 152

A company's marketing team created a new application and would like to create a DNS record for newapplication.comptia.org that always resolves to the same address as wwww.comptia.org. Which of the following records should the administrator use?

Answer options

• A. SOA
• B. MX
• C. CNAME
• D. NS

Correct answer: C

Explanation

The correct answer is CNAME because it allows one domain name to resolve to another, effectively pointing newapplication.comptia.org to wwww.comptia.org. SOA (A), MX (B), and NS (D) records serve different purposes such as defining zone authority, mail exchange, and name server information respectively, and do not provide the same functionality as a CNAME record.
