Explanation
Auto-QoS is a Cisco feature that automatically generates and applies QoS configurations based on Cisco best-practice templates for the detected interface type and traffic (e.g., VoIP, video, data). It dramatically reduces deployment time because the engineer does not need to manually classify traffic, write policy-maps, configure queuing, or set DSCP/CoS markings - the feature does it automatically with a single command per interface. Option A (DiffServ) is a QoS architecture that requires manual classification, marking, and per-hop behavior configuration on every device in the path - time-consuming but flexible. Option B (IntServ) requires per-flow RSVP signaling and reservation, making it the most complex and time-consuming to deploy. Option C (WRED) is a congestion avoidance/queue management mechanism, not a complete QoS deployment model.
