Which of the following utilities would BEST help diagnose NAS mount points?

The route utility displays and modifies the IP routing table; it can help trace path issues but does not reveal the interface-level configuration details needed to establish NAS connectivity.

ping tests basic ICMP reachability to a host but provides no information about the local interface configuration or mount-point state that would explain why a NAS mount is failing.

ifconfig displays the active configuration of network interfaces - including IP address, subnet mask, and interface state - which are the foundational prerequisites for a host to reach and mount a NAS device. Confirming that the correct interface is up and properly addressed is the first diagnostic step when NAS mount points are unavailable or unreachable.

nfsstat reports NFS client and server statistics for performance analysis of existing NFS sessions, but it does not surface the interface configuration details required to diagnose why a mount point cannot be established.
