PCNSA Policy Evaluation and Management Practice Question
Which THREE actions can be taken based on hit counts in security rules? (Select three.)
⚠ Common exam trap
The trap is selecting 'determine rule shadowing' because zero-hit rules seem related to shadowing, but hit counts alone cannot distinguish a shadowed rule from a simply unused one — shadowing requires rule-order analysis.

Correct answer & explanation
✓
Identify unused rules for cleanup
Hit counts record how many times each security rule has matched traffic, so option A is correct because rules showing zero or near-zero hits over a long period are strong candidates for removal during rule cleanup. Option C is correct because hit counts reveal which rules are heavily used versus rarely used, letting administrators focus optimization and consolidation efforts on the rules that matter most. Option D is correct because comparing expected traffic against actual hit counts helps diagnose why traffic is or is not matching a given rule, exposing mis-ordered or mis-scoped rules. Option B is not correct because hit counts are observational statistics and do not themselves trigger or generate dynamic rule updates. Option E is not correct because shadowing is determined by analyzing rule order and overlapping match criteria, not by hit-count values alone.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Identify unused rules for cleanup
Why this is correct
Hit counts expose rules matching no traffic, so unused rules can be identified for cleanup. This satisfies the scenario's requirement to act on hit count data by removing redundant policy, reducing rulebase bloat and administrative overhead without affecting legitimate traffic flows.
- ✗
Create dynamic updates to rules
Why it's wrong here
Hit counts inform analysis and rule ordering decisions; they do not themselves generate or push dynamic rule updates, which require external automation or the Dynamic Address Group mechanism. Hit counts are used to identify unused or heavily matched rules for manual tuning, not to rewrite rules automatically.
- ✓
Prioritize rule optimization efforts
Why this is correct
Hit counts reveal which rules match traffic frequently and which never fire, so optimisation effort can target redundant or unused rules rather than guessing. This directly satisfies the stem's requirement for an action based on hit counts, since the counters quantify each rule's actual usage.
- ✓
Troubleshoot traffic mis-matches
Why this is correct
Hit counts expose rules matching traffic they should not, or expected rules showing zero hits, pinpointing where policy ordering or criteria diverge from intent. This satisfies the stem's action requirement by using the counters as diagnostic evidence to locate and correct mis-matched traffic flows.
- ✗
Determine rule shadowing
Why it's wrong here
Hit counts reveal which rules never match, but shadowing is determined by comparing rule criteria and order, not counters. A shadowed rule simply shows zero hits, which is ambiguous with a genuinely unused rule, so hit counts alone cannot confirm shadowing; they are used to flag rules for manual review.
