第10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
