CompTIA Network+ (N10-009) — Question 345

An administrator requests a certificate for the company's domain name. In order to prove ownership of the domain, the certificate authority asks the administrator to create a specific DNS record. Which of the following record types is required?

Answer options

• A. SOA
• B. MX
• C. NS
• D. TXT

Correct answer: D

Explanation

The correct answer is D, TXT, because a TXT record is specifically used to validate domain ownership and can contain various types of text information, including verification data for certificate authorities. The other options, SOA, MX, and NS records, serve different purposes such as defining the start of authority, specifying mail exchange servers, and indicating name servers, respectively, and are not used for ownership validation.
