PCNSE Securing Traffic and App-ID Practice Question
Which TWO of the following are valid methods to create a custom App-ID on a Palo Alto Networks firewall?
⚠ Common exam trap
It's easy for candidates to confuse 'Create Application Override' (which bypasses App-ID) with 'Create App-ID' (which defines a new application), leading them to select option A, or they may mistakenly think the ACC can generate App-IDs, which it cannot.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Using the 'set application' command in the CLI.
The 'set application' CLI command allows you to define a custom App-ID by specifying characteristics such as protocol, port, and signature. This is a direct method to create a custom application object on a Palo Alto Networks firewall, as documented in the administrator's guide.
