4.7 Explain the Forwarding Per-Hop Behavior (PHB) for QoS Such as Classification, Marking, Queuing, Congestion, Policing, and Shaping 200-301 Practice Questions (Page 2)
Part of the IP Services domain, which accounts for 10% of the 200-301 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~5–8 in this domain), expect 1–1 from this objective — we provide 29 practice questions to prepare you well beyond it.
