CompTIA Network+ (N10-008) — Question 455

A technician is setting up DNS records on local servers for the company's cloud DNS to enable access by hostname. Which of the following records should be used?

Answer options

• A. A
• B. MX
• C. CNAME
• D. NS

Correct answer: A

Explanation

The correct answer is A, as 'A' records map domain names to IP addresses, enabling devices to locate servers by hostname. The other options serve different purposes: 'MX' records are for mail exchange, 'CNAME' records create aliases for domain names, and 'NS' records define the name servers for the domain, but none of these directly resolve hostnames to IP addresses.
