CompTIA Network+ (N10-009) — Question 417

A server administrator needs to add a record to the company’s DNS server to verify ownership of a web domain. The administrator has the record's name and value. Which of the following record types should the administrator use to add the record to the DNS server?

Answer options

• A. TXT
• B. A
• C. PTR
• D. CNAME

Correct answer: A

Explanation

The correct answer is A, TXT, as this record type is specifically used for adding text information to the DNS, including ownership verification. Options B, A, C, and D are not suitable for this purpose; A records map domain names to IP addresses, PTR records are used for reverse DNS lookups, and CNAME records are for aliasing one domain name to another.
