CompTIA Network+ (N10-008) — Question 411

A security vendor needs to add a note to the DNS to validate the ownership of a company domain before services begin. Which of the following records did the security company MOST likely ask the company to configure?

Answer options

• A. TXT
• B. AAAA
• C. CNAME
• D. SRV

Correct answer: A

Explanation

The correct answer is A, TXT, as TXT records are commonly used to verify domain ownership by adding a specific text string. The other options, such as AAAA, CNAME, and SRV, serve different purposes related to IP addressing and service location but are not used for domain ownership verification.
