Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 64

An administrator needs to optimize traffic to prefer business-critical applications over non-critical applications.
QoS natively integrates with which feature to provide service quality?

Answer options

• A. Port Inspection
• B. Certificate revocation
• C. Content-ID
• D. App-ID

Correct answer: D

Explanation

The correct answer is D, App-ID, because it identifies and classifies applications, allowing QoS to prioritize traffic based on application type. The other options, such as Port Inspection, Certificate revocation, and Content-ID, do not directly assist in traffic prioritization for service quality.
