Which two statements correctly describe VTP？（）

多项选择题Whichtwoofthefollowingstatementsdescribearoutedswitchportonamultilayerswitch？（）

A.Layer 2 switching and Layer 3 routing are mutually supported.
B.The port will not be associated with any VLAN.
C.The routed switch port supports VLAN subinterfaces.
D.The routed switch port is used when a switch has only one port per VLAN or subnet.
E.The routed switch port ensures that STP remains in the forwarding state.

多项选择题Which two of the following steps are necessary to configure inter-VLAN routing between multilayer switches？（）

A.Configure a dynamic routing protocol.
B.Configure SVI interfaces with IP addresses and subnet masks.
C.Configure switch ports with network addresses.
D.Configure switch ports with the autostate exclude command.
E.Document the MAC addresses of the switch ports.

单项选择题A switch that is to be added to the production network has been preconfigured （trunks， VLANs， VTP， and STP） and was tested in your lab. After installing the switch into the network， the entire network went down.  What might explain what happened？ （）

A.The new switch happened to be running Cisco Catalyst operating system， while the other network switches were running Cisco IOS Software.
B.The configuration revision of the new switch was higher than the configuration revision of the production VTP domain.
C.The link costs on the new switch are set to a high value， causing all ports on the new switch to go into a forwarding mode and none into blocking mode， thereby causing a spanning-tree loop.
D.The ports connecting to the two switches have been configured incorrectly. One side has the command switchport mode access and the other switchport mode trunk.

单项选择题You have just created a new VLAN on your network for inter-VLAN routing.   What is one step that you should include in your VLAN-based implementation and verification plan？（）

A.Verify that different native VLANs exist between two switches for security purposes.
B.Verify that the switch is configured to allow for trunking on the switch ports.
C.Verify that each switch port has the proper IP address space assigned to it for the new VLAN. 
D.Verify that the VLAN virtual interface has been correctly created and enabled.
