Topic #: 4
In a network with dozens of switches, how many root bridges would you have?
Suggested Answer: A Vote an answer
Spanning Tree Protocol (STP) is used in Ethernet switching environments to prevent loops. In any STP domain, only one switch is elected as the root bridge. All other switches determine the shortest path to this root bridge and may block redundant paths.
MTCNA Course Material - STP Basics:
"STP ensures a loop-free topology by electing a single root bridge. All path calculations are made from the root bridge's perspective." Rene Meneses MTCNA Study Guide - STP and Loop Prevention:
"Only one root bridge exists per STP domain. Switches use BPDU messages to elect it based on bridge ID priority." No matter how many switches exist (2, 10, or 50), only one root bridge is present at any time.
