Answer: B,D,E

Explanation:

Promiscuous Mode Event Actions

+ Request block host: This event action will send an ARC request to block the host for a specified time frame, preventing any further communication. This is a severe action that is most appropriate when there is minimal chance of a false alarm or spoofing.

+ Request block connection: This action will send an ARC response to block the specific connection. This action is appropriate when there is potential for false alarms or spoofing. + Reset TCP connection: This action is TCP specific, and in instances where the attack requires several TCP packets, this can be a successful action.
