Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 43

An administrator has configured a QoS policy rule and a QoS Profile that limits the maximum allowable bandwidth for the YouTube application. However, YouTube is consuming more than the maximum bandwidth allotment configured.
Which configuration step needs to be configured to enable QoS?

Answer options

• A. Enable QoS interface
• B. Enable QoS in the Interface Management Profile
• C. Enable QoS Data Filtering Profile
• D. Enable QoS monitor

Correct answer: A

Explanation

The correct answer is A because enabling the QoS interface is essential for the QoS policies to take effect on the network. Without activating the QoS interface, the configured rules and profiles will not be applied, allowing YouTube to exceed the bandwidth limit. Options B, C, and D do not directly enable QoS functionality on the interface level, which is critical in this scenario.
