PCNSA Security Profile Group (SPG) Practice Question
A large enterprise with thousands of security rules wants to reduce rule count without compromising security visibility. The current rules use many specific applications and services. Which strategy should be implemented to consolidate rules effectively?
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
✓
Consolidate rules using Security Profile Groups (SPGs) and broader application groups.
Consolidating rules using Security Profile Groups (SPGs) and broader application groups reduces rule count while maintaining visibility. SPGs allow multiple rules to share the same security profiles, reducing duplication, and application groups bundle related applications to minimize rule entries. Option A is incorrect as using default ports bypasses App-ID, losing application visibility. Option B is incorrect because converting to service objects removes application visibility and does not reduce rule count. Option D is incorrect; placing specific rules at the top does not reduce rule count—it only affects rule matching order.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use only default ports for services to avoid creating service objects.
Why it's wrong here
This weakens security by bypassing App-ID and losing application visibility.
- ✗
Convert all application-based rules to use service objects instead.
Why it's wrong here
Service objects ignore application context, reducing security effectiveness.
- ✓
Consolidate rules using Security Profile Groups (SPGs) and broader application groups.
Why this is correct
SPGs allow multiple rules to reference the same security profiles, reducing rule count while maintaining security posture.
- ✗
Place the most specific rules at the top of the rulebase.
Why it's wrong here
Rule ordering improves performance but does not reduce the number of rules.
