Which statement best describes the relationship between classification and marking in QoS?

Classification is performed only at the network edge, while marking is performed only at the core

Classification and marking are interchangeable terms for the same process

Classification groups packets into classes, while marking sets a field to represent that class

Classification assigns a priority value to packets, while marking groups packets into classes

What is the primary purpose of Weighted Random Early Detection (WRED) in QoS?

To guarantee bandwidth for all traffic classes

To shape traffic to a lower rate by buffering excess packets

To prevent congestion by randomly dropping packets before the queue becomes full

To reorder packets to improve throughput

What is the role of the token bucket in a traffic policer?

To buffer excess traffic until tokens become available

To measure the rate of traffic and determine if it conforms to the configured rate

To encrypt packets that exceed the rate

To reorder packets to improve throughput

Part of the Services domain, which accounts for 20% of the 350-501 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 2–3 from this objective — we provide 19 practice questions to prepare you well beyond it.
