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 two answers)

• The ip default-gateway command in VLAN configuration mode

• The ip address command in global configuration mode

• The password command in console line configuration mode

• The password command in vty line configuration mode

• The interface is configured with the shutdown command

• The show interface fa0/1 command will list the interface with two status codes of administratively down and line protocol down

• The show interface fa0/1 command will list the interface with two status codes of up and down

• The interface cannot currently be used to forward frames

Imagine that you are told that switch 1 is configured with the dynamic auto parameter for trunking on its Fa0/5 interface, which is connected to switch 2. You have to configure switch 2. Which of the following settings for trunking could allow trunking to work? (Choose two answers)

• Trunk

• Dynamic auto

• Dynamic desirable

Which of the following facts determines how often a non-root bridge or switch sends an STP Hello BPDU message?

• The Hello timer as configured on that switch

• The Hello timer as configured on the root switch

• It is always every 2 seconds

• The switch reacts to BPDU received form the root switch by sending another BPDU 2 seconds after receiving the root BPDU

An engineer configures a switch to put interfaces G0/1 and G0/2 into the same Layer 2 EtherChannel. Which of the following term is used in the configuration commands?

• EtherChannel

• PortChannel

• Ethernet-Channel

• Channel-group
