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?

Options

  • BCMX
  • CDSCP
  • DRXSOP

Why each option

AVC (Application Visibility and Control) uses deep packet inspection to identify applications and enables the WLC to block or throttle specific application traffic.

AAVCCorrect

AVC integrates NBAR2-based deep packet inspection into the wireless controller to classify traffic by application name and apply QoS policies that can block, rate-limit, or mark specific application flows. This directly addresses the requirement to suppress non-business traffic in high-density environments by giving the WLC granular, application-aware enforcement capabilities.

BCMX

CMX (Connected Mobile Experiences) is a location analytics and engagement platform used for tracking device positions and delivering proximity-based services, not for application traffic control.

CDSCP

DSCP is a packet marking mechanism for QoS prioritization in the IP header and cannot identify or enforce policies on specific named applications.

DRXSOP

RXSOP (Receive Start of Packet) is a threshold that controls the minimum signal level at which an AP processes incoming frames, affecting coverage and co-channel interference, not application-level traffic management.
