The correct answer is D. Ensure that the allocated memory is sufficient. Cisco FTD packet capture stores captured packets in a memory buffer. If the allocated buffer memory is too small for the volume of traffic during the 15-minute capture window, the buffer fills up and older (or new) packets are dropped, resulting in an incomplete capture.

Question
Network users experience issues when accessing a server on a different network segment. An engineer investigates the issue by performing packet capture on Cisco Secure Firewall Threat Defense. The engineer expects more data and suspects that not all the traffic was collected during a 15-minute can't captured session. Which action must the engineer take to resolve the issue?
Options
- AForward the captured data lo an FTP server
- BIncrease the amount of RAM allocated for the capture.
- CProvide a file name to save the data.
- DEnsure that the allocated memory is sufficient.

Explanation
Cisco FTD packet capture stores captured packets in a memory buffer. If the allocated buffer memory is too small for the volume of traffic during the 15-minute capture window, the buffer fills up and older (or new) packets are dropped, resulting in an incomplete capture. The engineer must ensure the allocated memory (buffer size) is sufficient to hold all traffic expected during the capture duration. Forwarding to an FTP server (A) offloads storage but does not fix the in-memory capture limitation during the session. RAM allocation (B) is a system-level concern, not directly configurable per capture. Providing a file name (C) saves the capture to disk but does not resolve a buffer overflow during active capture.
