Which nbtstat parameter allows viewing the contents of the NetBIOS name cache?

The correct option for viewing the contents of the NetBIOS name cache using the nbtstat command is indeed the -c parameter.

When using the -c flag with the nbtstat command, it displays the contents of the NetBIOS name cache, which includes a list of all resolved NetBIOS names and their corresponding IP addresses that the local machine has cached. This is particularly useful for troubleshooting name resolution issues on a network, as it allows you to see what names have been resolved recently and their associated addresses.

In contrast, other parameters serve different purposes. The -n parameter provides a list of NetBIOS names that the local machine is using (not the cache), the -r parameter displays the number of resolved names and the names that were successfully resolved from the broadcast names, and the -a parameter is used to display the NetBIOS name table for a specific remote host by specifying its IP address. Each of these parameters has its own specific function in managing or querying NetBIOS names, but the -c parameter focuses exclusively on the cache contents.
