- A
Set the Source Zone and Destination Zone.
Why wrong: Zones are required but not specific to application matching.
- B
Enable Threat Prevention.
Why wrong: Threat Prevention is a security profile, not a matching criterion.
- C
Set the Service to 'application-default'.
application-default restricts the rule to the application's default port.
- D
Configure Logging at session start.
Why wrong: Logging does not affect rule matching.
- E
Set the Application to the specific application.
The application field determines which app identity the rule matches.
Question 288 of 516
Which Two Settings Ensure a Security Policy Rule Matches a Specific Application on Its Standard Port?
This PCNSE practice question tests your understanding of securing traffic and app-id. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO settings must be configured in a security policy rule to ensure the rule only matches when a specific application is detected on its standard port?

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
✓
Set the Service to 'application-default'.
To ensure a security policy rule matches only when a specific application is detected on its standard port, two settings are required: Set the Application to the specific application to match that application's traffic, and set the Service to 'application-default' to restrict matching to the standard port used by that application. This prevents other applications using the same port from triggering the rule. The other options are not directly related to this requirement: Source and Destination zones are necessary for any rule but not specific to application/port matching; Threat Prevention is a separate feature; logging at session start is optional and does not affect matching.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 PCNSE 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.
