Designing Cisco Network Service Architectures (ARCH, legacy) — Question 42

Which STP feature can prevent other switches on the network from becoming the root switch, but still allow that interface to particiate in STP otherwise?

Answer options

Correct answer: A

Explanation

BPDU Guard is designed to prevent other switches from becoming the root by disabling ports that receive BPDUs from non-root switches, while still allowing the designated interface to participate in the STP process otherwise. The other options do not specifically address the prevention of root switch election while allowing participation in STP.
