Which of the following identifies the three modes in which Snort can be configured to run?

Snort's official documentation defines exactly three operational modes - Sniffer mode reads and displays network packets in real time, Packet Logger mode captures and writes packets to disk for later analysis, and Network Intrusion Detection System (NIDS) mode applies rule-based analysis to traffic and generates alerts. These three modes represent the core architecture of Snort as described in its design documentation.

Snort does not include a Host Intrusion Detection System (HIDS) mode; HIDS is a separate product category and not a built-in Snort operational mode.

Snort does not have a Host Intrusion Prevention System mode or a Network Intrusion Prevention System mode as its three defined run modes; IPS functionality is a separate consideration beyond the three base modes.

Host Intrusion Prevention System is not one of Snort's three defined operational modes; the third mode is NIDS, not HIPS.
