Why each option

Traffic storm control prevents network degradation by dropping excessive broadcast, multicast, or unicast traffic when configured thresholds are exceeded.

ATraffic storm control drops all broadcast and multicast traffic if the combined traffic exceeds theCorrect

Traffic storm control specifically aims to mitigate the impact of excessive broadcast, multicast, or unicast traffic by dropping packets that exceed a defined threshold. If the combined rate of these traffic types goes above the configured limit, the control mechanism will drop the excess frames to prevent network instability.

BTraffic storm control cannot determine if the packet is unicast or broadcast.

Traffic storm control can distinguish between unicast, broadcast, and multicast traffic, as it monitors and controls these types individually or in combination.

CTraffic storm control monitors incoming traffic levels over a 10-second traffic storm control

Traffic storm control typically monitors traffic over a user-configurable interval, often 1 second by default, not a fixed 10-second interval.

DTraffic storm control uses the Individual/Group bit in the packet source address to determine if the

Traffic storm control determines traffic type (broadcast, multicast) using the destination MAC address, specifically the Individual/Group bit, and not the source address.
