- A
Create two rules: one for general traffic with 'allow' action and a 'threat' profile, and a higher-priority rule for video conferencing traffic with 'allow' action and no threat profile.
This allows selective bypassing of threat inspection for video traffic while inspecting the rest.
- B
Create a single rule with 'allow' action and no security profiles, and rely on the firewall's default behavior to inspect malware.
Why wrong: Without a security profile, no threat inspection occurs at all.
- C
Create a single rule with 'allow' action and a 'threat' profile applied, and rely on the firewall's ability to skip inspection for video traffic automatically.
Why wrong: The firewall cannot automatically skip inspection for specific application types within a single rule; it would inspect all traffic matched by the rule.
- D
Use policy-based forwarding to route video traffic to a separate interface that has no security profiles.
Why wrong: Policy-based forwarding does not bypass security profiles; profiles are applied based on security rules, not forwarding.
Quick Answer
The correct approach is to create two security rules: a higher-priority rule for video conferencing traffic with an 'allow' action and no threat profile, and a lower-priority rule for general traffic with an 'allow' action and a threat profile. This works because Palo Alto Networks firewalls process rules from top to bottom, applying the first match; by placing the video conferencing rule above the general rule, you achieve a selective bypass of threat inspection for performance without compromising malware inspection on other traffic. On the PCNSA exam, this tests your understanding of rule ordering and profile application—a common trap is trying to use a single rule with exceptions or misplacing the priority. Remember the memory tip: “First match wins, so place your bypass rule above your inspection rule.”
PCNSA Policy Evaluation and Management Practice Question
This PCNSA practice question tests your understanding of policy evaluation and management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 network engineer needs to ensure that all traffic from the 'Guest' zone to the 'Internet' zone is inspected for malware, but also wants to allow high-bandwidth video conferencing traffic to bypass threat inspection for performance reasons. Which approach best achieves this?

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
Create two rules: one for general traffic with 'allow' action and a 'threat' profile, and a higher-priority rule for video conferencing traffic with 'allow' action and no threat profile.
Option A is correct because it uses two security rules with different priorities: a higher-priority rule for video conferencing traffic with an 'allow' action and no threat profile to bypass inspection, and a lower-priority rule for general traffic with an 'allow' action and a threat profile to enforce malware inspection. This leverages the firewall's rule-ordering logic, where the first matching rule is applied, allowing selective bypass of threat inspection for specific traffic while maintaining security for other traffic.
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 may assume the firewall can automatically detect and exempt video traffic from inspection without explicit rule configuration, or that a single rule with a threat profile can be configured to skip inspection for certain applications, but Palo Alto firewalls require separate rules or profile exceptions to achieve selective bypass.
Detailed technical explanation
How to think about this question
In Palo Alto Networks firewalls, security rules are evaluated in order from top to bottom, and the first matching rule determines the action and applied security profiles. By placing a higher-priority rule for video conferencing traffic (e.g., matching on application 'zoom' or 'webex') with no threat profile, the firewall bypasses threat inspection for that traffic, while a subsequent rule for general guest-to-internet traffic applies a threat profile. This approach ensures performance-sensitive traffic is not delayed by deep packet inspection, which can introduce latency, while maintaining security for other traffic.
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.
