Which QoS model allows hosts to report their QoS needs to the network?
The correct answer is C. IntServ. IntServ (Integrated Services) is the QoS model that allows end hosts and applications to signal their bandwidth and delay requirements to the network using the RSVP (Resource Reservation Protocol). The network then reserves resources along the path per-flow to guarantee QoS. Diff

Explanation
IntServ (Integrated Services) is the QoS model that allows end hosts and applications to signal their bandwidth and delay requirements to the network using the RSVP (Resource Reservation Protocol). The network then reserves resources along the path per-flow to guarantee QoS. DiffServ uses DSCP markings at the packet level with per-hop behaviors but does not involve per-flow host signaling. CB-WFQ (Class-Based Weighted Fair Queuing) is a queuing scheduling algorithm, not a QoS signaling model. MQC (Modular QoS CLI) is a Cisco configuration framework for defining and applying QoS policies.
