Which switch feature prevents traffic on a LAN from being overwhelmed by continuous multicast or broadcast traffic?

A.
storm control

B.
port security

C.
VTP pruning

D.
VLAN trunking

Explanation:
A traffic storm occurs when packets flood the LAN, which creates excessive traffic and degrades network performance. The traffic storm control feature prevents
LAN ports from being disrupted by a broadcast, multicast, or unicast traffic storm on physical interfaces from either mistakes in network configurations or from users
issuing a DoS attack.
