In a traditional 3 tier topology, an engineer must explicitly configure a switch as the root bridge and exclude it from any further election process for the spanning-tree domain. Which action accomplishes this task?

• A.Configure the spanning-tree priority to 32768
• B.Configure root guard and portfast on all access switch ports.
• C.Configure BPDU guard in all switch-to-switch connections.
• D.Configure the spanning-tree priority equal to 0.

Correct Answer: B

Explanation

Root guard does not allow the port to become a STP root port, so the port is always STP-designated. If a better BPDU arrives on this port, root guard does not take the BPDU into account and elect a new STP root. Instead, root guard puts the port into the root-inconsistent STP state which is equal to a listening state. No traffic is forwarded across this port.
