In a TCP/IP network, the service most associated with domain name resolution is:

• A. DNS
• B. DHCP
• C. LDAP
• D. FTP

Answer: (A)

The main idea is mapping human-friendly hostnames to IP addresses, which is handled by DNS. When you enter a domain like example.com, your device asks a DNS resolver to translate that name into the numerical IP address needed to reach the server. DNS is designed as a distributed naming system with a hierarchy of servers and caches, so name resolution happens quickly and reliably across the Internet. It uses port 53 and typically operates over UDP for simple queries, switching to TCP for larger transfers or zone updates. DHCP, on the other hand, assigns IP addresses and related network configuration to hosts automatically, but it does not resolve domain names. LDAP provides directory services and is used for querying and updating directory information, not for name-to-address translation. FTP is a protocol for transferring files and is unrelated to resolving domain names. Therefore, DNS is the service most associated with domain name resolution.
