Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 501

An administrator is receiving complaints about application performance degradation. After checking the ACC, the administrator observes that there is an excessive amount of VoIP traffic.

Which three elements should the administrator configure to address this issue? (Choose three.)

Answer options

• A. A QoS policy for each application
• B. An Application Override policy for the SIP traffic
• C. A QoS profile defining traffic classes
• D. QoS on the ingress interface for the traffic flows
• E. QoS on the egress interface for the traffic flows

Correct answer: A, C, E

Explanation

Implementing a QoS policy for each application (A) ensures that VoIP traffic is prioritized appropriately. Creating a QoS profile defining traffic classes (C) helps categorize the VoIP traffic for better management. Applying QoS on the egress interface for traffic flows (E) guarantees that outgoing traffic is handled efficiently. Options B and D do not specifically address the prioritization and management of the excessive VoIP traffic.
