    To eliminate the possibility of a broadcast storm, switches and bridges implement the ____.

    • A.

      RIP (Routing Information Protocol)

    • B.

      STP (Spanning Tree Protocol)

    • C.

      BGP (Border Gateway Protocol)

    • D.

      OSPF (Open Shortest Path First) protocol

    Correct Answer
    B. STP (Spanning Tree Protocol)
    Explanation
    To eliminate the possibility of a broadcast storm, switches and bridges implement the Spanning Tree Protocol (STP). STP is a network protocol that prevents loops in Ethernet networks by creating a loop-free logical topology. It achieves this by selecting a root bridge and then determining the best path from each bridge to the root bridge. Any redundant paths are blocked, ensuring that there are no loops in the network. This prevents broadcast storms, which can occur when broadcast or multicast packets are continuously forwarded in a loop, causing network congestion and degradation.
