Which protocol prevents Layer 2 switching loops by placing redundant links into a blocking state?
a.Spanning Tree Protocol
b.Border Gateway Protocol
c.Hot Standby Router Protocol
d.Network Time Protocol
解析
Spanning Tree Protocol (STP) detects redundant Layer 2 paths and blocks them to prevent broadcast storms and switching loops. If an active link fails, a blocked link can transition to forwarding. STP is essential in networks with redundant switch links.
