In the following exhibit, RIP is running on all of the routers. On Router A, you want to make sure that if Router B fails then a backup route is used through Router C to Network B. Which statement will achieve this?

A. RouterA(config)#ip route 192.168.2.8 255.255.255.252 192.168.2.6
B. RouterA(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.6 220
C. RouterA(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.6 90
D. RouterA(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.10

B. The backup route to network 192.168.3.0/24 is though the gateway of 192.168.2.6. However, the administrative distance of a normal static route is 1. So the AD must be higher than RIP, which is 120. An AD of 220 is higher than 90, so the RIP route will be the main route and the static route will become the backup floating route.
