What is the purpose of the Spanning Tree Protocol (STP)?

A.To prevent routing loops

B.To create a default route

C.To provide multiple gateways for hosts

D.To maintain a loop-free Layer 2 network topology

E.To enhance the functions of SNMP

参考答案
正确答案:D
解析:Explanation:
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.
