An administrator needs to test the latency between two servers. Which of the following commands should be used?

The route command displays or modifies the local IP routing table and does not measure latency or send any test traffic.

The arp command displays or manages the Address Resolution Protocol cache that maps IP addresses to MAC addresses and does not test connectivity or latency.

Ping transmits ICMP Echo Request packets to a target and measures the time in milliseconds for each Echo Reply to return, which is a direct measurement of round-trip latency. It provides per-packet timing statistics including minimum, maximum, and average RTT, making it ideal for quickly diagnosing latency between two servers. No other command listed provides this round-trip time measurement.

nslookup and dig are DNS query tools used to resolve hostnames to IP addresses; they do not measure network latency between two servers.
