What is the function of the DNS Client service in Windows operating systems?

• A. Resolving computer names to IP addresses
• B. Querying the DNS server to locate domain controllers
• C. Caching DNS records for all domains
• D. Blocking DNS queries to external servers

Answer: (A)

The DNS Client service translates host names into IP addresses by querying configured DNS servers. When you try to reach a computer by name, Windows uses this service to resolve that name to its numeric IP so communication can occur. It also caches recent resolutions to speed up repeated lookups and reduce network traffic, updating entries as TTLs expire. It isn’t primarily about locating domain controllers, blocking queries, or caching records for all domains—the main function is name resolution.
