A network administrator is configuring QoS on a multi-hop path. The administrator wants to ensure that voice traffic is prioritized on every router along the path. What is the most important consideration for per-hop behavior?

The last router must re-mark all traffic.

Only the first router needs to classify and mark traffic.

QoS is applied only at the edge of the network.

Each router must be configured with the same QoS policy.

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.
