Which service resolves domain names to IP addresses?

• A. WINS
• B. DNS
• C. DHCP
• D. COMPOSE Tools Folder

Answer: (B)

Translating a human-friendly domain name into the numeric IP address computers use to route traffic is what domain name resolution is all about. The service that provides this translation across the internet and on networks is the Domain Name System. DNS lets devices look up a name, consult a resolver, and retrieve the corresponding IP, often using a cascade of servers from root to top-level domains to authoritative records, with caching to speed repeated lookups. This enables you to access sites by name rather than by remembering their numbers.

Other options don’t fit because they serve different purposes: WINS handles NetBIOS name resolution in some Windows networks but isn’t the general mechanism for resolving domain names to IPs; DHCP assigns IP addresses to devices rather than translating names to addresses; COMPOSE Tools Folder isn’t a networking service.
