The answer is that the rule's action must be set to 'allow' and a security profile group containing threat prevention must be applied. This is required because the firewall’s threat prevention inspection engine only examines traffic that is permitted by a security rule; a deny or drop action blocks the session before any content inspection can occur, while an allow action lets the traffic through for the security profiles to analyze. On the Palo Alto Networks Certified Network Security Administrator PCNSA exam, this question tests your understanding of how security rules and profiles interact—specifically that threat prevention is a profile-based feature, not a rule action itself. A common trap is assuming that logging or SSL decryption is mandatory, but decryption is only needed for encrypted traffic, not for all threat inspection. Remember the memory tip: "Allow to inspect, profiles to protect"—the rule allows the session, and the attached profile group performs the actual threat prevention inspection.
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.
An administrator wants to ensure that traffic from the corporate network to the internet is inspected by the firewall's threat prevention features. Which TWO of the following are required to achieve this? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a security rule that allows the traffic and includes a security profile group with threat prevention.
Options A and C are correct. A security rule with action 'allow' and a security profile group containing threat prevention is necessary to inspect traffic. Option B is optional for encrypted traffic but not required for all. Option D is not required for inspection. Option E is not needed.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 decryption to inspect encrypted traffic.
Why it's wrong here
Decryption is needed for encrypted traffic but not for all traffic.
Create a security rule that allows the traffic and includes a security profile group with threat prevention.
Why this is correct
The rule must allow traffic and apply the threat prevention profile.
Related concept
Static NAT maps one inside address to one outside address.
✓
Ensure the rule's action is set to 'allow'.
Why this is correct
Security profiles are only applied when the action is allow.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use application override to force detection.
Why it's wrong here
Application override is for forcing application identification, not for inspection.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCNSA NAT questions on configuration and troubleshooting.
