Refer to the exhibit.
Which two statements are true about interVLAN routing in the topology that is shown in the exhibit? (Choose two.)
A. Host E and host F use the same IP gateway address.
B. Router1 and Switch2 should be connected via a crossover cable.
C. Router1 will not play a role in communications between host A and host D.
D. The FastEthernet 0/0 interface on Router1 must be configured with subinterfaces.
E. Router1 needs more LAN interfaces to accommodate the VLANs that are shown in the exhibit.
F. The FastEthernet 0/0 interface on Router1 and Switch2 trunk ports must be configured using the same encapsulation type.
Correct Answer: DF
Each VLAN is its own broadcast domain, hence its own subnet. We need the router to route packets between subnets. However, the router is only connected to
Switch 2 with a single cable. Therefore, for the router to be a member of all VLANs (so as to route packets between them), it needs a trunk line to Switch2 as
shown. But this means that the single interface must have multiple IP addresses, and this can only occur when that interface has sub-interfaces, each one with its
own IP address (D). And if the line between the router and switch is a trunk line, it must be configured using the same trunk protocol, 802.1q or ISL.
