Refer to the exhibit below. Which two statements about the configuration of the switch interface are correct?
SwitchA(config)#interface fa0/0
SwitchA(config-if)#switchport access vlan 2
- The switchport belongs only to VLAN 2.
- By default, all switch ports are members of VLAN 1005.
- Interface fa0/0 will be in both VLAN 1 (by default) and VLAN 2.
- The exhibit shows interface fa0/0 to be dynamically mapped to VLAN 2.
- A network host can be connected to this interface.

Refer to the exhibit. Which two statements are true about interVLAN routing in the topology that is shown in the exhibit?
- Host E and host F use the same IP gateway address.
- Router1 and Switch2 should be connected via a crossover cable.
- Router1 will not play a role in communications between host A and host D.
