Question 7/178

Loops may cause broadcast storms on a Layer 2 network.

A. TRUE

B. FALSE

Correct Answer: A

Comprehensive and Detailed In-Depth Explanation:
In a Layer 2 (switching) network, loops occur when there are multiple paths between switches without a loop prevention mechanism (e.g., STP - Spanning Tree Protocol). This causes:
* Broadcast Storms (infinite loops of broadcast frames)
* MAC Table Instability (conflicting learning of MAC addresses)
* High CPU Usage (due to excessive traffic processing)
Spanning Tree Protocol (STP) prevents these loops by blocking redundant links while keeping one active path.
