This PCNSE practice question tests your understanding of manage, monitor and operate. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security engineer is investigating a potential data exfiltration incident. The firewall logs show that a host in the DMZ made outbound connections to multiple external IPs on port 443, but the traffic was allowed. The engineer wants to review detailed session information including the amount of data transferred and the application used. Which three log types or tools should the engineer use? (Choose three.)
App-ID logs.
App-ID logs show the application identified for each session.
Packet capture feature.
Packet capture can record actual packets for detailed analysis.
System logs.
Why wrong: System logs are for administrative events, not session data.
URL filtering logs.
Why wrong: URL filtering logs show URLs visited, but not necessarily data transfer amounts.
Traffic logs.
Traffic logs contain byte counts, source/destination, and duration.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
App-ID logs.
App-ID logs (option A) are correct because they provide detailed information about the application associated with each session, which is critical for identifying the specific application used in the outbound connections. Traffic logs (option E) are correct because they record session-level details including source/destination IPs, ports, and the amount of data transferred (bytes sent/received). The packet capture feature (option B) is correct because it allows the engineer to capture and inspect the actual packets for forensic analysis, revealing the exact data payload and application behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse URL filtering logs with traffic logs, thinking URL filtering provides session data transfer details, but URL filtering only logs URL categories and not byte counts or application identity.
Trap categories for this question
Command / output trap
URL filtering logs show URLs visited, but not necessarily data transfer amounts.
Detailed technical explanation
Traffic logs in Palo Alto Networks firewalls include fields such as 'bytes_sent', 'bytes_received', and 'app' (application identified by App-ID), which are essential for quantifying data exfiltration. The packet capture feature can be configured to capture full packets or just headers, and when combined with App-ID, it can reveal if the traffic is using non-standard ports for a given application (e.g., SSH over port 443). In a real-world scenario, an attacker might use HTTPS on port 443 to tunnel data, but App-ID would identify the actual application (e.g., 'ssl' vs 'web-browsing') and the packet capture would show the encrypted payload.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
