SSE-Engineer Prisma Access Troubleshooting Practice Question
An enterprise has deployed Prisma Access with explicit proxy and transparent proxy configurations. Users are reporting that applications using custom non-standard TCP ports are failing to connect through the Remote Network node. What feature should the engineer inspect to ensure the ports are allowed through App-ID inspection?
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
✓
Inspect the custom application definitions and ensure Custom App-IDs are mapped to the correct non-standard ports, and that security rules permit those ports.
App-ID inspects traffic dynamically, but if custom ports are used, Custom App-IDs or Service objects must be correctly configured in security policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Inspect the custom application definitions and ensure Custom App-IDs are mapped to the correct non-standard ports, and that security rules permit those ports.
Why this is correct
By default, App-ID identifies applications regardless of port, but custom applications or strict service object definitions require explicit configuration in policies.
- ✗
Configure a static NAT rule for the non-standard ports on the service connection.
Why it's wrong here
NAT does not resolve App-ID misclassification or port blocking by security policies.
- ✗
Disable GlobalProtect pre-logon mode.
Why it's wrong here
Pre-logon mode affects machine authentication prior to user login, not custom port traffic handling.
- ✗
Enable SSL Forward Proxy on the destination zones.
Why it's wrong here
SSL Forward Proxy decrypts HTTPS traffic and does not govern custom non-standard TCP port recognition.
