Question

A server on the network is unreachable. What is the best method to verify connectivity between your computer and the remote server?

Options

  • Alookup
  • Bfind
  • Cping
  • Dnetstat

Explanation

The ping command is the best method to verify basic network connectivity and reachability between two hosts by sending ICMP echo requests.

Common mistakes.

  • A. lookup (or nslookup/dig) is used for DNS resolution, not for verifying network reachability to a host.
  • B. find is a Linux command used for locating files and directories, unrelated to network connectivity.
  • D. netstat displays network connections, routing tables, and interface statistics, which is useful for analyzing network state, but not for actively testing reachability to a remote server.
