Which utility is BEST suited to diagnose NAS mount points and related network interfaces?

• A. route
• B. ping
• C. ifconfig
• D. nfsstat

Answer: (C)

Diagnosing NAS mount points hinges on understanding the network interface status and configuration. The tool that best helps with this is one that shows the actual network interfaces, their IP addresses, and whether they’re up and capable of carrying traffic. Ifconfig reveals which interfaces are active, what IPs they have, MTU, and their current state. This lets you confirm that the host has a valid network path to the NAS, that the correct interface is in use, and that the interface isn’t down or misconfigured (which would prevent the NAS mount from succeeding). The other options don’t provide the same breadth of network-interface visibility. Route shows routing decisions but not the detailed status of each interface. Ping tests reachability to a host but doesn’t expose interface configuration or status. Nfsstat gives statistics about NFS activity, not about the network path or interface health. So, if you need to diagnose why a NAS mount point isn’t working, checking the interface with a command that reports on the interface’s state and IP configuration is the most direct and informative first step.
