What command is used to show names in the netbios cache?

NBTSTAT -c
NBTSTAT -R
NBTSTAT -RR
NBTSTAT -a computername

The correct answer is: NBTSTAT -c

The command NBTSTAT -c displays the contents of the NetBIOS name cache. This command is useful for troubleshooting name resolution issues in a Windows network environment, as it allows the user to view the NetBIOS names that have been resolved and cached by the system. By examining this cached data, you can determine if the names are correctly mapped to their associated IP addresses, which can be helpful in diagnosing connectivity or naming problems. The other options serve different purposes: NBTSTAT -R is used to purge and reload the remote cache name table, while NBTSTAT -RR sends Release and Refresh requests to the WINS server for all names that are registered with it. NBTSTAT -a followed by a computer name queries the remote machine for its NetBIOS name table instead of showing the local cache. Each of these commands has distinct functions, but in this case, NBTSTAT -c specifically fulfills the requirement of showing names in the NetBIOS cache.
