   A network administrator is configuring storm control on a switch port that connects to a server. The server is known to generate a high amount of multicast traffic for software updates. The administrator wants to ensure that a multicast storm does not affect other parts of the network. What is the most appropriate configuration?

   • ASet a broadcast storm control threshold and apply it to the port.
   • BSet the multicast threshold to 1% to ensure no multicast storm can occur.
   • CSet a multicast storm control threshold that is high enough for normal updates but low enough to catch a storm.
   • DDisable storm control on the port because the server is trusted.

   A network engineer is troubleshooting an access port that keeps going down. The logs show that storm control is enabled and the interface was shut down due to a broadcast storm. After the storm subsides, the interface does not come back up automatically. What is the most likely reason for this behavior?

   • AThe interface is administratively down because the storm control threshold was exceeded.
   • BThe spanning-tree protocol placed the interface in a blocking state after the storm.
   • CThe interface is waiting for the storm control hold-down timer to expire before re-enabling.
   • DThe storm control action is configured to 'shutdown', which requires manual intervention to re-enable the interface.
