PCNSE Securing Traffic and App-ID Practice Question
An administrator wants to apply different security policies for different applications that may use the same IP addresses and ports. Which firewall configuration feature should be used?
⚠ Common exam trap
Watch out — candidates often confuse Application Override with App-ID, thinking that manually overriding application classification is the solution, when in fact App-ID automatically identifies applications and allows policy differentiation without manual intervention.
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
✓
Security policy with App-ID
App-ID is the correct feature because it enables the firewall to identify and enforce security policies based on the application, regardless of the IP address or port used. This allows different security policies for different applications even when they share the same IP and port, such as HTTP and FTP both using TCP/80.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Application Override
Why it's wrong here
Override bypasses App-ID, not suitable for granular policy based on application.
- ✗
Quality of Service (QoS) policy
Why it's wrong here
QoS manages bandwidth, not application filtering.
- ✓
Security policy with App-ID
Why this is correct
Security rules can match on application identity, allowing per-application policies.
- ✗
Decryption policy
Why it's wrong here
Decryption policy controls decryption, not application-based access.
