考题
Which of the following characteristics describe the BPDU Guard feature（）A、ABPDU Guard port should only be configured on ports with PortFast enabled.B、BPDU Guard and PortFast should not be enabled on the same port.C、BPDU Guard is used to ensure that superior BPDUs are not received on a switch port.D、ABPDU Guard port receiving a BPDU will go into err-disablestate.E、ABPDU Guard port receiving a BPDU will be disabled.F、BPDU Guard can be enabled on any switch port.
考题
关于spanning-treeportfast说法正确的是（）A、不发送BPDU，但接受BPDU，一旦接收到BPDU后，就开始恢复生成树的转发延迟等特性B、发送BPDU，接受BPDU，一旦接收到BPDU后，会进行生成树协议计算C、发送BPDU，不接受BPDUD、即不发送BPDU，也不接受BPDU，因为portfast表明了所连接的接口是主机端口，没有必要发送和接收BPDU
