Which two statements are true about trust boundaries？（）A、Classifying and marking traffic should be done as close to the traffic source as possible. B、Classifying and marking traffic should be done at the distribution layer.C、Traffic is classified and marked as it travels through the network.D、If untrusted traffic enters a switch， it can be marked with a new QoS value appropriate for the policy in place.E、The trust boundary moves depending on the type of traffic entering the network.
流分类和ACL的区别说法错误的是（）。A、在基于类的QoS中，流分类即traffic classifier，它是以ACL为基础的，但不同于ACLB、流分类只有分类匹配一个作用，而没有表明对符合分类的流做出什么动作C、ACL本身是为了访问控制，所以附带有deny和permit的动作D、二者匹配的范围不同，就目前而言，流分类所能匹配的流范围小于等于ACL
多选题Which two QoS statements are true about the use of the SDM QoS wizard？ （）ABusiness-critical traffic includes VoIP and voice signaling packets.BSDM can be used to configure a basic QoS policy for incoming traffic on WAN interfaces and IPsec tunnels.CSDM can provide QoS for real-time traffic and business-critical traffic.DSDM creates a custom-queuing （CQ） or a priority-queuing （PQ） policy.ESDM creates a low latency queuing （LLQ） service policy with its associated classes.FWhen allocating bandwidth， values can be entered in either bandwidth percentage or kilobytes per second （kBps）.
