PCNSA Policy Evaluation and Management Practice Question
Which TWO are best practices for managing security policies in a Palo Alto Networks firewall?
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
✓
Place most specific rules at the top of the rulebase.
Placing the most specific rules at the top of the rulebase (option B) ensures that traffic is matched quickly and correctly, reducing latency. Regularly reviewing and removing unused rules using hit counts (option D) improves performance and reduces security risks. Option A is wrong because enabling logging on all rules can overwhelm storage and impact performance, not increase visibility effectively. Option C is wrong because using a single 'allow all' rule defeats the purpose of a security policy and allows any traffic. Option E is wrong because disabling unused rules leaves clutter and can cause confusion; it's better to remove them.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable logging on all rules for maximum visibility.
Why it's wrong here
Logging everything can overwhelm logs and storage; log only relevant rules.
- ✓
Place most specific rules at the top of the rulebase.
Why this is correct
Specific rules should be first to avoid unnecessary matching and ensure intended behavior.
- ✗
Use a single 'allow all' rule to simplify management.
Why it's wrong here
An allow all rule reduces visibility and security; it is not a best practice.
- ✓
Regularly review and remove unused rules using hit counts.
Why this is correct
Removing unused rules reduces policy complexity and potential misconfigurations.
- ✗
Disable unused rules instead of removing them.
Why it's wrong here
Disabled rules still exist and can cause confusion; removal is cleaner.
