Which statement best describes the function of DNS?

• A. Translates domain names to IP addresses
• B. Encrypts data in transit
• C. Stores files on servers
• D. Routes email messages

Answer: (A)

Domain name resolution maps human-friendly names to IP addresses, enabling devices to locate resources on the network. When you type a domain, a DNS resolver looks up the numeric address associated with that domain, and your browser uses that address to connect to the correct server. This translation is what DNS primarily does. Encrypting data in transit is handled by TLS/SSL, storing files on servers is the job of hosting/file servers, and routing email is managed by mail servers identified through DNS records (MX), but DNS’s main function is the name-to-address look-up.
