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
以下动作不属于生成树协议(STP)中拓扑改变信息泛洪动作的是()。
A.当某个交换机发现拓扑改变后,会从其根端口向其上游交换机发送一个拓扑改变通知BPDUB.指定端口收到拓扑改变通知BPDU之后,用拓扑改变确认配置BPDU应答并且向上继续泛洪拓扑改变通知BPDU直到根交换机C.根交换机收到拓扑改变通知BPDU之后,用拓扑改变确认配置BPDU应答并且从所有端口向外发送拓扑改变配置BPDUD.根交换机收到拓扑改变通知BPDU之后,从所有端口向外发送拓扑改变配置BPDU
考题
生成树协议使用的配置BPDU中不包括()。
A.网络中的根交换机的交换机标识B.发送该配置BPDU的交换机到达根交换机最短路径开销C.发送此配置BPDU的端口的端口标识D.接收此配置BPDU的端口的端口标识

Which four Cisco Spanning Tree Protocol enhancements are supported with rapid per-VLAN Spanning-Tree plus?()
A. PortFastB. UplinkFastC. loop guardD. root guardE. BPDU guardF. BackboneFast
考题
在同一端口上启用了BPDU防护和BPDU过滤,以下描述正确的是()A、BPDU防护生效,BPDU过滤失效B、BPDU防护失效,BPDU过滤生效C、BPDU防护和BPDU过滤同时生效D、BPDU防护和BPDU过滤冲突,都失效
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 two statements are true about BPDU port-guard and BPDU filtering?()A、BPDU port-guard can be enabled globally, whereas BPDU filtering must be enabled on a per-interface basis.B、When globally enabled, BPDU port-guard and BPDU filtering apply only to PortFast enabled ports.C、When globally enabled, BPDU port-guard and BPDU filtering apply only to trunking-enabled ports.D、When a BPDU is received on a BPDU port-guard enabled port, the interface goes into the err-disabled state.E、When a BPDU is received on a BPDU filtering enabled port, the interface goes into the err-disabled state.F、When a BPDU is received on a BPDU filtering enabled port, the interface goes into the STP blocking state.
