In promiscuous mode, which statement best describes the NIC's behavior?

Discard only packets addressed to this NIC. Discard any packet addressed to another NIC. Accept and process every packet it receives. Filter packets by protocol and port.

Correct Answer:

Accept and process every packet it receives.

Explanation:

Promiscuous mode removes the NIC’s usual destination-based filtering, so the adapter passes all frames it sees up to the host rather than discarding those not addressed to it. This allows packet sniffers to capture traffic not intended for this machine. Because of this behavior, the NIC effectively accepts and processes every packet it receives. The other statements describe normal filtering or selective processing, which is not what promiscuous mode does.
