Refer to the exhibit. Host A and Host B are connected to the Catalyst 3550 switch and have been assigned to their respective VLANs. The rest of the 3550 configuration is the default configuration. Host A is able to ping its default gateway, 10.10.10.1, but is unable to ping Host B. Given the output displayed in the exhibit, which statement is true?

A.
A separate router is required to support interVLAN routing.

B.
VTP must be configured to support interVLAN routing.

C.
VLANs 10 and 15 must be created in the VLAN database mode.

D.
The global configuration command “ip routing” must be configured on the SW1 switch.

E.
HSRP must be configured on SW1.

F.
Interface VLAN 10 must be configured on the SW1 switch.

Explanation:

To transport packets between VLANs, you must use a Layer 3 device. Traditionally, this has been a router’s function. The router must have a physical or logical connection to each VLAN so that it can forward packets between them. This is known as interVLAN routing. Multilayer switches can perform both Layer 2 switching and interVLAN routing, as appropriate. Layer 2 switching occurs between interfaces that are assigned to Layer 2 VLANs or Layer 2 trunks. Layer 3 switching can occur between any type of interface, as long as the interface can have a Layer 3 address assigned to it. Switch(config)#ip routing command enables the routing on Layer 3 Swtich
