Why each option

To mitigate network traffic interruption caused by excessive broadcast packets, Storm Control should be configured on network devices, based on a predefined threshold, to prevent flooding.

ABridge Protocol Data Unit guard

Bridge Protocol Data Unit (BPDU) guard protects the Spanning Tree Protocol (STP) domain by shutting down ports that receive unexpected BPDUs, and it does not specifically address broadcast storms.

Bembedded event monitoring

Embedded Event Monitoring (EEM) allows for customized, on-device event detection and action scripting, but it is a general-purpose automation tool, not a specific mechanism to prevent broadcast storms by thresholding.

Caccess control lists

Access Control Lists (ACLs) can filter traffic based on various criteria but are not primarily designed for dynamic, threshold-based rate limiting of broadcast traffic to prevent storms.

DStorm ControlCorrect

Storm Control is a network feature that monitors incoming traffic levels for specific types of packets, such as broadcast, multicast, or unknown unicast. It drops packets that exceed a configured threshold, effectively preventing broadcast storms from flooding the network and causing service disruptions.
