What is the purpose of Spanning Tree Protocol?
A.
to provide multiple gateways for hosts
B.
to maintain a loop-free Layer 2 network topology
C.
to prevent routing loops
D.
to create a default route
Explanation:
STP (Spanning Tree protocol) is able to overcome transparent bridge in network redundancy.
Through the use of non-loop path, STP is able to avoid and eliminate network loops. It may locate
the loop and cut off link redundancy.
STP’s main task is to stop network loops from occurring on your Layer 2 network (bridges or
switches). It vigilantly monitors the network to find all links, making sure that no loops occur by
shutting down any redundant ones. STP uses the spanning-tree algorithm (STA) to first create a
topology database, then search out and destroy redundant links. With STP running, frames will
only be forwarded on the premium, STP-picked links.
