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.
考题
In the Cisco FabricPath domain， one switch becomes the root for the multidestination tree. Cisco FabricPath switches compare which three parameters to select the root？ （）A、 Root priorityB、 System IDC、 Bridge IDD、 Switch IDE、 Port IDF、 Subswitch ID
考题
Which MST configuration statement is correct？ （）A、 MST configurations can be propagated to other switches using VTP.B、 After MST is configured on a Switch， PVST+ operations will also be enabled by default.C、 MST configurations must be manually configured on each switch within the MST region.D、 MST configurations only need to be manually configured on the Root Bridge.E、 MST configurations are entered using the VLAN Database mode on Cisco Catalyst switches.
考题
As a network administrator， can you tell me what the root guard feature provides in a bridgednetwork？（）A、It ensures that BPDUs sent by the root bridge are forwarded in a timely mannerB、It enforces the root bridge placement in the networkC、It ensures that all ports receiving BPDUs from the root bridge are in the forwarding state.D、It ensures that the bridge is elected as root bridge in the network.
考题
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.
