Correct! Wrong!

Which of the following commands prevents a 2960 switch interface fa0/1 from attempting to form a trunk and just be a member of VLAN 10?

Correct! Wrong!

Refer to the exhibit and diagram; to make it possible for all traffic to pass between PC1’s LAN and PC2’s LAN, the link between SW1 and SW2 will be configured as a trunk. Which Cisco IOS command could be used on SW1’s Gi0/1 interface to force it to actively attempt to trunk with SW2?

Correct! Wrong!

Which of the following commands identify switch interfaces as being trunking interfaces: interfaces that currently operate as VLAN trunks?

Correct! Wrong!

A switch has just arrived from Cisco. The switch has never been configured with any VLANs, but VTP has been disabled. An engineer configures the vlan 22 and name Hannahs-VLAN commands, and then exits configuration mode. Which of the following is true?

Which type of Layer 2 frames will be forwarded to all other ports in the same VLAN as the port where the frame was received?

Correct! Wrong!

Switch SW1 uses its Gigabit 0/1 interface to connect to switch SW2’s Gigabit 0/2 interface. SW2’s Gi0/2 interface is configured with the speed 1000 and duplex full commands. SW1 uses all defaults for interface configuration commands on its Gi0/1 interface. Which of the following is true about the link after it comes up?
