In which of the following scenarios would the "show cdp neighbors detail"command be an appropriate troubleshooting tool?（）A、Two switches are connected via a trunk. Both switches have been assigned an IP address, subnet mask, and default gateway. A ping is successful between the two switches. However, VLAN information is not passed from one switch to the other switch.B、A router and a switch have been assigned an IP address, a subnet mask, and a default gateway. They are directly connected, but a ping between the two devices fails.C、A router connects to another router through a serial interface. Both routers have been assigned an IP address, subnet mask, and default gateway. The routers are running RIP and the networks directly connected to the first router do not pass to the second router. However, a ping from one router to the serial interface of the directly connected neighboring router is successful.D、A router connects to another router via a switch. Both routers and the switch have been assigned an IP address, subnet mask, and default gateway. Neither the routers nor the switch are able to ping one of the hosts that is directly to the switch.

As an experienced network engineer, you are asked to troubleshoot a CIS network outage. During the troubleshooting process, you notice that one of your colleagues connects additional devices to the network with the use of his own switch. With the purpose of improving speed, the switch is attached to both network ports in an office, which leads to bridge loop. Enabling which of the following feature will be able to prevent this problem from happening again?（）A、GLBPB、RSTPC、BPDU guardD、root guard

A network administrator needs to force a high-performance switch that is located in the MDF to become the root bridge for a redundant path switched network. What can be done to ensure that this switch assumes the role as root bridge（）。A、Establish a direct link from the switch to all other switches in the network.B、Assign the switch a higher MAC address than the other switches in the network have.C、Configure the switch so that it has a lower priority than other switches in the network.D、Configure the switch for full-duplex operation and configure the other switches for half-duplex operation.E、Connect the switch directly to the MDF router, which will force the switch to assume the role of root bridge.
Which statement is correct about RSTP port roles？（）A、The designated port is the switch port on every nonroot bridge that is the chosen path to theroot bridge. There can be only one designated port on every switch. The designated portassumes the forwarding state in a stable active topology. All switches connected to a given segment listen to all BPDUs and determine the switch that will be the root switch for a particular segment.B、The disabled port is an additional switch port on the designated switch with a redundant link to the segment for which the switch is designated. A disabled port has a higher port ID than the disabled port on the designated switch. The disabled port assumes the discarding state in astable active topology.C、The backup port is a switch port that offers an alternate path toward the root bridge. The backup port assumes a discarding state in a stable， active topology. The backup port will be present on nondesignated switches and will make a transition to a designated port if the current designated path fails.D、The root port is the switch port on every nonroot bridge that is the chosen path to the root bridge. There can be only one root port on every switch. The root port assumes the forwarding state in a stable active topology.
What is one benefit of PVST+？（）A、PVST+reduces the CPU cycles for all the switches in the networkB、PVST+automatically selects the root bridge location，to provide optimiz…C、PVST+allow the root switch location to be optimized per vlan.D、PVST+supports Layer 3 load balancing without loops.
