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
✓
The application signature does not match the traffic's port or pattern.
For custom applications, you must ensure the 'Signature' tab has the correct port and protocol, and that the application is correctly referenced in the policy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The application signature does not match the traffic's port or pattern.
Why this is correct
If the traffic pattern doesn't match the signature criteria, the firewall will not identify it as the custom app.
- ✗
The application must be assigned to the 'web' category.
Why it's wrong here
Category is for organization, not for security policy matching.
- ✗
The App-ID must be added to a service group.
Why it's wrong here
App-IDs are used in policy, not service groups.
- ✗
The application requires an SSL decryption policy first.
Why it's wrong here
While helpful, it is not strictly required for signature-based identification.
