問題 #456
A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DM VPN back to the hub with two 10-Mbps internet connections. The branch routers are multivendor and have limited memory and CPU resources. Which routing protocol and design solution meets the requirements?
答案：D
問題 #457
The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?
答案：C
解題說明：
For streaming multimedia over a WAN using DiffServ per-hop behavior, the best answer is CBWFQ with DSCP AF3. Cisco QoS design separates real-time interactive voice from streaming multimedia. Voice bearer traffic commonly uses EF and a strict priority queue because it is extremely sensitive to delay and jitter.
Streaming multimedia, however, is usually buffered and bandwidth-intensive; it should receive assured bandwidth and controlled drop behavior rather than strict priority treatment. The Assured Forwarding classes are designed for this kind of preferential forwarding within DiffServ. AF3 is commonly associated with multimedia streaming in Cisco QoS baseline models, while CBWFQ provides bandwidth guarantees without allowing the class to starve other traffic. LLQ with EF is too aggressive for streaming multimedia and should be reserved for voice bearer traffic or similarly strict real-time flows. AF2 is more commonly used for transactional data or lower-priority assured service, depending on the model. The correct marking and queuing design is therefore CBWFQ with DSCP AF3. Reference topics: DiffServ, per-hop behavior, CBWFQ, DSCP AF classes, multimedia streaming QoS.
