An engineer’s desktop PC connects to a switch at the main site. A router at the main site connects to each branch office through a serial link, with one small router and switch at each branch. Which of the following commands must be configured on the branch office switches, in the listed configuration mode, to allow the engineer to telnet to the branch office switches and supply only a password to login? (Choose three answers.)

An engineer’s desktop PC connects to a switch at the main site. A router at the main site connects to each branch office through a serial link, with one small router and switch at each branch. Which of the following commands must be configured on the branch office switches, in the listed configuration mode, to allow the engineer to telnet to the branch office switches and supply only a password to login? (Choose three answers.)

• The ip address command in interface configuration mode
• The ip address command in global configuration mode
• The ip default-gateway command in VLAN configuration mode
• The ip default-gateway command in global configuration mode
• The password command in console line configuration mode
• The password command in vty line configuration mode

Explanation: To allow access through Telnet, the switch must have password security enabled, at a minimum using the password vty line configuration subcommand. In addition, the switch needs an IP address (configured under one VLAN interface) and a default gateway when the switch needs to communicate with hosts in a different subnet.
