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