An administrator must fix a network problem whereby traffic from the inside network to a webserver is not getting through an instance of Cisco Secure Firewall Threat Defense. Which command must the administrator use to capture packets to the webserver that are dropped by Secure Firewall Threat Defense and resolve the issue?
To capture packets that are dropped by Cisco Secure Firewall Threat Defense, the correct command would involve capturing information about packets that are specifically being dropped by the system. The command 'capture CAP type asp-drop all headers-only' (option D) is designed for this purpose as it captures the packets dropped by the firewall for all reasons, which is essential for diagnosing issues related to packet drops.
My choice is A
The question doesn't specify the packets dropped.
(A) and (C) could be valid answers. However, (C) restricts the troubleshooting massively by saying that the client tcp source port must be 80. In regular connection requests, those source ports are randomized... So, answer (A) should be the correct one.
