Show commands: show running-config, show version, show ip interface brief, show interfaces, show interfaces status, show ip route, show mac address-table, show cdp neighbors, show inventory

Show commands display information without changing anything, which makes them safe for support technicians to run. Many work in user EXEC mode, but some, such as show running-config, need privileged EXEC mode (the # prompt), so it is simplest to run them from there. Knowing which command answers which question is heavily tested and is exactly what an engineer will ask you to run.
