Question 170
An analyst needs a capture of DNS queries on a headless Linux server without GUI access. What is the MOST appropriate analyst action based on the evidence?
Explanation
Correct Answer
Command-line packet capture can collect targeted traffic on headless systems. Capture DNS evidence via tcpdump.
Incorrect Answers
Stream reassembly exposes application exchange across multiple packets. It could help reconstruct single HTTP exchange from pcap, but it would not capture DNS evidence via tcpdump.
Sensor vantage point can omit reverse traffic when mirroring is incomplete. It would diagnose partial SPAN port visibility, but it would not capture DNS evidence via tcpdump.
Packet payloads may contain sensitive authentication and personal data. It could help minimize sensitive packet evidence collection, but it would not capture DNS evidence via tcpdump.
