A.it is a layer 2 messaging protocol which maintains vlan configurations across network.
B.it includes an 8-bit field which specifies the priority of a frame.
C.it is used exclusively for tagging vlan frames and dose not address network reconvergence following switched network topology changes.
D.it modifies the 802.3 frame header,and thus requires that the FCS be recomputed.
E.it is a trunking protocol capable of carring untagged frames.

What can be determined from the line of show ip route output shown in the exhibit？（）
A. The next routing update can be expected in 35 seconds.
B. The IP address 10.10.10.6 is configured on S0/1.
C. The IP address 10.10.10.8 is configured on S0/1.
D. This route is using the default administrative distance.
E. The 10.10.10.8 network is two hops away from this router.
A.Microsegmentation decreases the number of collisions on the network.
B.if a switch receives a frame for an unkown destination,it uses ARP to resolve the address.
C.Spanning Tree Protocol allows switches to automatically share vlan information.
D.In a properly functioning network with redundant switched paths,each switched aegment will contain one root bridge with all its ports in the forwarding state.All other switches in that broadcast domain will have only one root port.
E.Establishing vlans increases the number of broadcast domains.
F.Switches that are configured with vlans make forwarding decisions based on both layer 2 and layer 3 address information.
S0/0 on R1 is configured as a multipoint interface to communicate with R2 and R3 in the hub-and-spoke Frame Relay topology shown in the exhibit. Originally， static routes were configured between these routers to successfully route traffic between the attached networks. What will need to be done in order to use RIPv2 in place of the static routes？（）
A.Configure the no ip subnet-zero command on R1,R2,and R3.
B.Dynamic routing protocols such as RIPv2 cannot be used across Frame Relay networks.
C.Configure the S0/0 interface on R1 as two subinterfaces and configure point-to-point links to R2 and R3.
D.Change the 172.16.2.0/25 and 172.16.2.128/25 subnetworks so that at least two bits are borrowed from the last octet.
E.Change the network address configuration to eliminate the discontiguous 172.16.2.0/25 and 172.16.2.128/25 subnetwork.

C. the IP address of Host C
D. the MAC address of Host C
E. the IP address of the router’s E0 interface
F. the MAC address of the router’s E0 interface
An administrator is unsuccessful in adding VLAN 50 to a switch. While troubleshooting the problem，the administrator views the output of the show vtp status command， which is displayed in the graphic. What commands must be issued on this switch to add VLAN 50 to the database？（）
