Cisco Designing Cisco Enterprise Networks Sample Questions (Q199-Q204):

NEW QUESTION # 199
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:
The correct model is a 4-class QoS strategy with DiffServ. The traffic classes listed in the question are explicitly DiffServ per-hop behaviors: Expedited Forwarding for conversational traffic, Assured Forwarding class 2 for streaming, and Assured Forwarding class 3 for web or interactive traffic. Cisco QoS guidance uses DiffServ to classify and mark traffic with DSCP values, then apply per-hop behavior at each node along the path. This gives scalable end-to-end treatment across a provider backbone without maintaining per-flow reservations. The four service treatments implied are conversational, streaming, interactive/web, and background or best effort, which matches the stated service categories without unnecessary class expansion.
IntServ is not appropriate for an ISP backbone because it uses RSVP-style per-flow signaling and state, which scales poorly compared with DiffServ PHB handling. The 8-class and 12-class options add complexity beyond the stated mappings. Reference topics: DiffServ, DSCP, EF, AF2, AF3, per-hop behavior, provider QoS design.
