GCIA · Question #42
What is the easiest way to verify that name resolution is functioning properly on a TCP/IP network?
The correct answer is B. Ping the source host with its computer name. Pinging a host by its computer name tests whether the name resolution process (DNS or NetBIOS) is successfully translating hostnames to IP addresses.

Why each option
Pinging a host by its computer name tests whether the name resolution process (DNS or NetBIOS) is successfully translating hostnames to IP addresses.
TRACERT does not have a /pingname parameter - this option does not exist, making this choice technically invalid.
Pinging a host using its computer name forces the OS to perform name resolution before sending any ICMP packets. If the ping succeeds, it confirms that the resolver (DNS, WINS, or hosts file) correctly mapped the name to an IP address, making it the most direct and simplest test of name resolution functionality.
Pinging by IP address bypasses name resolution entirely and only confirms basic IP connectivity, providing no information about whether name resolution is functioning.
Checking IP statistics on a file server provides performance or error data but does not verify whether hostname-to-IP resolution is working correctly.
