0Why is a root bridge elected for STP to function properly?
Answer Options
A
The root bridge is the logical center of the STP topology.
B
The root bridge allows all forwarding decisions of frames.
C
The root bridge calculates the port cost for the rest of the network.
D
The root bridge calculates the fastest path for the rest of the network.
Correct Answer: A
Explanation
The root bridge is a point of perspective for the rest of the STP network. It is important to have a point of perspective to calculate which ports are blocked and which remain in a forwarding mode. The root bridge has no influence on the forwarding decisions of frames. Each switch is responsible for its own calculation of STP; only the root bridge election is the consensus of all switches in the network.
