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 swiched aegment will contain oneroot bridge with all its ports in the forwarding state.All other switches in that broadcast domain will haveonly 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 3address information.

A . The diesel oil must never be allowed to mix with the heavy fuel B . The temperature of the fuel from the pre–heater should be gradually reduced after switching over the three–way valve C . The heating steam to the pre-heater should be secured as soon as the diesel fuel passes through the three-way valve D . The heating steam must be secured before the diesel oil passes through the three-way valve

A . Bridges are faster than switches because they have fewer ports. B . A switch is a multiport bridge. C . Bridges and switches learn MAC addresses by examining the source MAC address of each frame received. D . A bridge will forward a broadcast but a switch will not. E . Bridges and switches increase the size of a collision domain.
