Computer Networks - Physical and Data Link Layer

A bridge is causing a network loop in a LAN. What is the most effective way to prevent this?

ADisable all bridge ports.

BReplace the bridge with a hub.

CEnable Spanning Tree Protocol (STP) on the bridge.

DIncrease the bridge's MAC address table size.

Step-by-Step Solution

Solution:

Step 1: Understand network loops and their prevention
Network loops cause broadcast storms; STP prevents loops by blocking redundant paths.
Step 2: Evaluate options
Disabling ports or replacing with hubs does not solve loops; increasing MAC table size is unrelated.
Final Answer:
Enable Spanning Tree Protocol (STP) on the bridge. -> Option C
Quick Check:
Loop prevention method = STP enabled [OK]

Quick Trick: Use STP to prevent network loops on bridges [OK]
