Answer options

• A. tcp_port_scan
• B. ip_dst_session
• C. udp_flood
• D. ip_src_session

Correct answer: A

Explanation

The correct answer is A, tcp_port_scan, as it can be configured to monitor and control the number of sessions on specific ports, including those used for SMTP. The other options, while relevant to different types of network monitoring, do not specifically target the throttling of SMTP sessions.
