200-201 Network Intrusion Analysis Practice Question
Which tool can be used to extract files from a PCAP file for further analysis?
⚠ Common exam trap
Cisco often tests the distinction between packet capture tools (tcpdump) and protocol analysis tools (Wireshark), leading candidates to mistakenly think tcpdump can extract files because it can read PCAPs, but it only outputs raw packet data without application-layer reconstruction.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Wireshark (Export Objects)
Wireshark's 'Export Objects' feature allows you to extract files (e.g., HTTP objects, SMB files, or other application-layer payloads) from a PCAP file. This is essential for further analysis of malware or data exfiltration, as it reconstructs the original files from the captured network streams without needing to replay the traffic.
