STP交换机会发送BPDU。关于BPDU的说法正确的是()。A.BPDU是使用IEEE802.3标准的帧B.BPDU是使用EtherentII标准的帧C.BPDU帧的Control字段值为3D.BPDU帧的目的MAC地址为广播地址
考题
BPDU防护有何用途?()
A.确保端口从正确的上游交换机那里收到了BPDUB.禁止端口接收来自上游交换机的BPDU,而只接收来自根交换机的BPDUC.可在启用了BPDU防护的端口上使用PortFast,在端口收到BPDU时将其关闭D.在端口收到BPDU时将其关闭
考题
在STP协议中,配置信息是通过BPDU协议数据包来进行转发的,那么对于配置BPDU报文,以下说法正确的是()
A.配置BPDU不能在指定端口上发送B.配置BPDU只能在指定端口上发送C.配置BPDU能够在任意角色的端口上发送D.以上说法都不正确
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

考题
Which of the following characteristics describe the BPDU Guard feature?(Choose all that apply.)()A、A BPDU Guard port should only be configured on ports with PortFast enabledB、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 portD、A BPDU Guard port receiving a BPDU will go into err-disable stateE、A BPDU Guard port receiving a BPDU will be disabledF、BPDU Guard can be enabled on any switch port
考题
Which statement correctly describes enabling BPDU guard on an access port that is also enabled for PortFast?()A、Upon startup, the port transmits 10 BPDUs. If the port receives a BPDU, PortFast and BPDU guard are disabled on that port and it assumes normal STP operation.B、The access port ignores any received BPDU.C、If the port receives a BPDU, it is placed into the error-disable state.D、BPDU guard is only configured globally and the BPDU filter is required for port-level configuration.
