The exhibit shows three switches interconnected using RSTP.

What is the role of Port B?

Your network consists of four EX Series switches, configured with the following STP parameters:
S1: Bridge address – F F:33:44:77 ; Bridge priority – 16k
S2: Bridge address – F F:33:44:66 ; Bridge priority – 12k
S3: Bridge address – F F:33:44:99 ; Bridge priority – 8k
S4: Bridge address – F F:33:44:88 ; Bridge priority – 4k
Given this information, which device will become the root bridge?

— Exhibit —
In the exhibit, the switches have all been powered on at the same time and have the factory
default RSTP configuration.
Which action would ensure that Switch A becomes the root bridge?

You are troubleshooting a spanning tree problem and must quickly determine the cumulative cost
to the root bridge.
Which CLI command should you use?

You have four interconnected switches all using default RSTP parameters. You are asked to
ensure that S1 becomes the root bridge.
Which configuration will accomplish this task?

— Exhibit –

— Exhibit —
You manage the network shown in the exhibit. All four switches have the default RSTP settings.
The elected root bridge is switch-1. You must ensure that switch-4 always prefers the connection
to switch-3 to reach the root bridge.
Which two configurations will accomplish this task? (Choose two.)
