In an eleven-class queueing model following realtime, best effort, and scavenger queuing rules, what recommended percentage of bandwidth must be allocated for interactive video?
The correct answer is C. 15%. Cisco's recommended 11-class QoS model allocates specific bandwidth percentages to each traffic class. Interactive video (e.g., videoconferencing) is assigned 15% of total bandwidth. This sits below voice (priority queue, ~18%) but above call signaling and other data classes…

Explanation
Cisco's recommended 11-class QoS model allocates specific bandwidth percentages to each traffic class. Interactive video (e.g., videoconferencing) is assigned 15% of total bandwidth. This sits below voice (priority queue, ~18%) but above call signaling and other data classes. These allocations follow Cisco's QoS best practices for enterprise collaboration networks and are tested on CCNP Collaboration and related exams. The 11-class model categorizes traffic into realtime (voice, interactive video), best effort (bulk data, scavenger), and management classes, each with defined bandwidth guarantees.
