Question

Quizplus · Accepted Answer

BPDU is mainly used in Spanning Tree Protocol (STP) to identify and prevent loops in the network by exchanging information with other switches. The information carried in BPDU includes the bridge ID, root bridge ID, cost to the root bridge, and lowest-cost path to the root bridge. These pieces of information are used to identify the best path for data to flow through the network and to identify and disable redundant paths, which prevents loops from forming. Therefore, the correct answer is E, redundant path identification.
