This PCNSA practice question tests your understanding of decryption and monitoring. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 Palo Alto firewall administrator wants to monitor SSL decryption efficiency. Which log type provides the most detailed information about decryption actions and reasons for not decrypting?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Decryption logs
Decryption logs are specifically designed to record detailed information about SSL decryption actions, including whether traffic was decrypted, not decrypted, or bypassed, along with the exact reason (e.g., unsupported cipher, certificate mismatch, excluded category). This granularity is essential for monitoring decryption efficiency and troubleshooting decryption policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
System logs
Why it's wrong here
System logs cover firewall system events, not decryption-specific details.
✓
Decryption logs
Why this is correct
Decryption logs provide comprehensive data including decryption reason, certificate info, and cipher details.
Related concept
Read the scenario before looking for a memorised answer.
✗
Traffic logs
Why it's wrong here
Traffic logs show decryption action (decrypt, no-decrypt) but lack detailed reasons like certificate validation errors.
✗
Threat logs
Why it's wrong here
Threat logs capture threats and vulnerabilities, not decryption statistics.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Traffic logs (which show a decryption flag) with Decryption logs (which provide the detailed reason), leading them to choose Traffic logs as the most detailed source when Decryption logs are the correct answer.
Trap categories for this question
Command / output trap
Traffic logs show decryption action (decrypt, no-decrypt) but lack detailed reasons like certificate validation errors.
Detailed technical explanation
How to think about this question
Decryption logs include fields such as 'Decryption Action' (e.g., decrypt, no-decrypt, forward-proxy, ssh-proxy), 'Decryption Reason' (e.g., unsupported-protocol, certificate-error, excluded-category), and 'SSL/TLS Version' negotiated. In a real-world scenario, if a large percentage of traffic shows 'no-decrypt' due to 'unsupported-cipher', the administrator can identify legacy clients and adjust decryption policies or cipher profiles to improve coverage.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PCNSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
