Dns — Cisco CCNA (200-301) Practice Questions
DNS (Domain Name System) is the hierarchical, distributed naming system that translates human-readable hostnames into IP addresses, enabling devices to communicate without requiring users to memorize numeric addresses. On the CCNA 200-301 exam, candidates must understand the DNS resolution process, the roles of recursive resolvers and authoritative name servers, and how to configure a Cisco router to use a DNS server for name resolution. DNS is also relevant in troubleshooting scenarios where connectivity failures stem from name resolution rather than routing or addressing problems.
