Multiple choice Why is spanning tree protocol used for bridged ethernet local area network? For minimizing contention For a loop free topology For fault tolerance For minimizing collisions For increasing the network bandwidth Reveal answer Fill a bubble to check yourself B Correct answer Explanation The Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged ethernet local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
