第4题：
SDM creates a low latency queuing （LLQ） service policy with its associated classes. What are the two types of low latency queuing available using the SDM QoS wizard？（）
- A、 FIFO queuing， which provides a means to hold packets while they are waiting to exit an interface
- B、 Priority queuing， which ensures a fixed amount of bandwidth
- C、 Custom queuing （CQ）， which provides a queuing tool that services all queues， even during times of congestion
- D、 Bandwidth queuing， which ensures a minimum amount of bandwidth
- E、 Weighted fair queuing （WFQ）， which classifies packets based on flows
正确答案:B,D
第5题：

第6题：
Which two statements or sets of statements are true about the application of the qos pre-classify command？（）
- A、 If the classification policy is based upon the ToS byte， the qos pre-classify command is required because the ToS byte only appears in the inner IP header.
- B、 The ToS byte is copied to the outer header by default. Therefore， the qos pre-classify command is not necessary.
- C、 With GRE encapsulation， the qos pre-classify command is applied on the tunnel interface. This practice allows for different OoS configurations on each tunnel.
- D、 With GRE encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.
- E、 With IPsec encapsulation， the qos pre-classify command is applied on the physical interface. This practice allows for different OoS configurations on each interface.
正确答案:B,C
