Question
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.)
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
Answer
B. An Application Override policy for the SIP traffic
C. A QoS profile defining traffic classes
E. QoS on the egress interface for the traffic flows
Explanation
To address the issue of application performance degradation caused by excessive VoIP traffic, the administrator should configure the following three elements:
B. An Application Override policy for the SIP traffic:
- An Application Override policy allows the administrator to control the behavior of specific applications, such as SIP traffic for VoIP. By creating an Application Override policy, the administrator can prioritize SIP traffic to improve VoIP performance.
C. A QoS profile defining traffic classes:
- QoS (Quality of Service) profiles define traffic classes based on various criteria such as source, destination, application, or service. By configuring QoS profiles, the administrator can prioritize different types of traffic, including VoIP, to ensure better performance under congestion.
E. QoS on the egress interface for the traffic flows:
- Configuring QoS on the egress interface allows the administrator to prioritize traffic leaving the network. By assigning appropriate QoS policies to the egress interface, the administrator can ensure that VoIP traffic receives preferential treatment, reducing latency and improving overall application performance.
