The correct answer is A. AVC. This question tests knowledge of the WLC feature that provides application-layer visibility and policy enforcement to block or rate-limit non-business application traffic.
Question
A network engineer is designing a high capacity WLAN for a conference area. The enterprise is concerned about non business traffic consuming excessive bandwidth and impacting performance. What can be used in the design to allow the controller to block or throttle applications?

Why each option
This question tests knowledge of the WLC feature that provides application-layer visibility and policy enforcement to block or rate-limit non-business application traffic.
Application Visibility and Control (AVC) uses Cisco NBAR2 (Network Based Application Recognition) to classify traffic by application type, enabling the WLC to enforce policies that block, drop, or throttle specific applications - directly addressing the need to control non-business traffic in high-capacity WLAN environments.
RxSOP (Receive Start of Packet) controls the minimum signal threshold for packet decoding to manage cell size and reduce co-channel interference, and has no ability to identify or control application traffic.
DSCP (Differentiated Services Code Point) is a QoS marking mechanism used to prioritize traffic classes, but it does not provide application identification, blocking, or throttling capabilities.
Cisco CMX (Connected Mobile Experiences) is a location services and analytics platform focused on client tracking and presence detection, not application-level traffic control.
