Question

When the show spanning-tree vlan 33 command is issued on a switch, three ports are shown in the forwarding state. In which two port roles could these interfaces function while in the forwarding state? (Choose two.)

A) Disabled
B) Designated
C) Root
D) Alternate
E) Blocked

Answer 1

The interfaces in the forwarding state when issuing the command 'show spanning-tree vlan 33' could be functioning as Designated or Root ports, as these facilitate the forwarding of traffic in a network.

Step-by-step explanation:

When the show spanning-tree vlan 33 command is issued on a switch, and three ports are shown in the forwarding state, these interfaces could function in two possible port roles while in the forwarding state. Those two roles are B) Designated and C) Root ports. A designated port is one that has been determined by the spanning tree protocol to be the best port to use for forwarding traffic towards the root bridge for that particular network segment, while a root port is the port that is closest to the root bridge in terms of path cost.

Ports in the disabled, alternate, or blocked states would not be forwarding traffic. Disabled ports are not active, alternate ports are backup ports that might take over if the designated port fails, and blocked ports are prevented from forwarding to stop loops in the network.
