NEW QUESTION # 74
Mobile service provider "A" is going to launch 5G support with the ISP "B" IP network backbone as the underlay transport. Conversational traffic type will be marked with expedited forwarding class, streaming services will be marked with assured forwarding 2 class, and web browsing will be marked with assured forwarding 3 class. Which QoS model meets these requirements if the solution is to be implemented end to end on the ISP_B backbone network?
Answer: C
Explanation:
An 8-class QoS strategy with the DiffServ model supports end-to-end service differentiation across an IP backbone using DSCP markings such as expedited forwarding for conversational traffic and assured forwarding classes for streaming and web traffic. DiffServ is the scalable QoS model typically used across provider backbone networks because traffic is classified and treated by class rather than requiring per-flow reservations.
