Which switch command would a network administrator use to determine if there are encapsulation or media errors on an interface?

• show arp
• show ip interface
• show line
• show interfaces

Explanation: The show interfaces command is useful to detect media errors, to see if packets are being sent and received, and to determine if any runts, giants, CRCs, interface resets, or other errors have occurred. The show ip interface command is useful in seeing whether the interface is "up and up". The output of the show line command displays parameters for active lines that are in use such as the vty line used for Telnet. The show arp command shows the contents of the Address Resolution Protocol (ARP) table.
