Configure the switch to be in VTP client mode. B. Configure the switch to be in VTP domaint mode. C. Configure the switch to be in VTP transparent mode. D. Configure the switch to be in VTPv2.

QUESTION 434

You are working in a data center environment and are assigned the address range 10.188.31.0/23.You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each.Which IP address range meets these requirements? A. 10.188.31.0/27 B. 10.188.31.0/26 C. 10.188.31.0/29 D. 10.188.31.0/28 E. 10.188.31.0/25

QUESTION 435

Which three statements accurately describe layer 2 Ethernet switches?(choose three) 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.
