What is a consequence of using shaping to smooth traffic bursts?

Increased delay for excess traffic

Which technique is used to avoid buffer overflow by dropping packets probabilistically before a queue becomes completely full?

Weighted random early detection (WRED)

A network administrator is configuring QoS on a router and wants to prioritize traffic from a specific IP address range. The administrator plans to mark this traffic with a DSCP value. Which classification method should be used to identify the traffic?

Using a queueing algorithm to prioritize the traffic.

Using a policy map to set the DSCP value.

Using a class map that matches on DSCP values.

Using an access control list (ACL) to match the source IP address range.

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.
