Why each option

To prevent network disruptions caused by excessive broadcast packets exceeding a predefined threshold, Storm Control must be configured on a Cisco Catalyst switch.

ADHCP Snooping

DHCP Snooping is a security feature that prevents unauthorized DHCP servers and protects against DHCP starvation attacks, not broadcast storms.

BEmbedded Event Monitoring

Embedded Event Monitoring (EEM) is a flexible tool for event detection and onboard automation, not directly for mitigating broadcast storms.

CStorm ControlCorrect

Storm Control is a Cisco Catalyst switch feature designed to prevent network performance degradation due to excessive broadcast, multicast, or unknown unicast traffic. It monitors traffic levels and, when a user-defined threshold is surpassed, it can drop packets or shut down the port to prevent a network storm.

DLoop Guard

Loop Guard is a Spanning Tree Protocol (STP) enhancement that prevents STP forwarding loops when a port's STP state transitions incorrectly, rather than controlling broadcast traffic volume.
