Exam 300-430 topic 1 question 22 discussion

C is correct.

To ensure high-quality WebEx meetings on the wireless network, the engineer must implement AVC (Application Visibility and Control) profiles. Here’s why: AVC Profiles: AVC allows the network to identify and classify specific applications, such as WebEx, and apply appropriate QoS policies to them. By creating an AVC profile for WebEx, the engineer can remark the QoS value (e.g., DSCP or UP) for WebEx traffic, ensuring it receives the necessary priority and bandwidth for high-quality performance. How it works: AVC uses deep packet inspection (DPI) to recognize application traffic. Once identified, the traffic can be marked with the appropriate QoS value and prioritized accordingly.

Correct answer is C.

C. Application Visibility & Control (AVC) allows: • Deep Packet Inspection in the wireless controller – allows application identification, remarking, rate limiting, and dropping of unwanted traffic.

For optimum performance, the network must recognize Webex traffic, mark it with a DSCP (Differentiated Services Code Point) value, and prioritize the flows as they traverse the network. Without proper protection, congestion can cause performance impacts to both Webex communication traffic on highly utilized enterprise networks. This congestion typically occurs at the WAN edge and Internet perimeter.Provided answer is correct.
