- A
The security policy rule's logging setting
The rule may have 'Log at Session End' set to 'None' instead of 'Enabled', which would suppress logs.
- B
The interface management profile
Why wrong: The management profile controls access to the firewall's management interface, not traffic logging.
- C
The log retention settings
Why wrong: Retention settings affect how long logs are stored, not whether they are generated.
- D
The system log severity level
Why wrong: System log severity is unrelated to traffic log generation.
Question 291 of 516
Why Traffic Logs Not Generated for Allowed Traffic? Check Rule Logging Setting
This PCNSE practice question tests your understanding of troubleshoot. 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 security administrator notices that traffic logs are not being generated for allowed traffic from a specific subnet. The security policy rule for that subnet has 'Log at Session End' enabled. What should the engineer check?
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
✓
The security policy rule's logging setting
Even though the security policy rule has 'Log at Session End' enabled, logs may still not be generated if the setting is not correctly applied to the rule or if a logging profile overrides it. The engineer should verify the rule's logging configuration to ensure it is properly set and that no other rule or logging profile is suppressing the logs. Option A is correct because checking the logging setting on the rule is the first step to troubleshoot missing logs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Log at Session End' with other logging mechanisms (like system logs or interface management) and assume logs are generated by default for allowed traffic, when in fact they must be explicitly enabled per security policy rule.
Detailed technical explanation
How to think about this question
Under the hood, the firewall's dataplane processes traffic and, at session end, checks the security policy rule's 'log-end' flag. If enabled, the session is queued for logging; if not, no log is generated even if the session was allowed. A common subtlety is that if a rule has 'Log at Session Start' enabled but not 'Log at Session End', only session start logs are generated, which can mislead administrators into thinking logging is fully enabled. In real-world scenarios, overlapping rules or rule order can cause traffic to match a different rule without logging, so verifying the exact rule hit count and logging configuration is critical.
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 network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
