In the following exhibit, packets with a destination of 192.168.4.0/24 from 192.168.1.0/24 travel from Router A to Router B. However, the best path is Router A to Router C to Router B. Which configuration change for EIGRP will allow the best path to be used?

A.	RouterA(config)# interface serial 0/0
	RouterA(config-if)# bandwidth 64
	RouterB(config)# interface serial 0/0
	RouterB(config-if)# bandwidth 64
B.	RouterA(config)# interface serial 0/1
	RouterA(config-if)# bandwidth 1544
	RouterC(config)# interface serial 0/0
	RouterC(config-if)# bandwidth 1544
	RouterC(config)#interface serial 0/1
	RouterC(config-if)# bandwidth 1544
	RouterB(config)# interface serial 0/1
	RouterB(config-if)# bandwidth 1544
C.	RouterA(config)# interface serial 0/0
	RouterA(config-if)# bandwidth 64000
	RouterB(config)# interface serial 0/0
	RouterB(config-if)# bandwidth 64000
D.	RouterA(config)# ip route 192.168.4.0 255.255.255.0 serial 0/1

A. Serial interfaces will default to 1.544 Mb/s. They will not autocorrect the actual bandwidth. Therefore, changing the bandwidth between Router A and Router B will allow EIGRP to calculate the best route through Router C. This is done by using the bandwidth command and specifying bandwidth in Kb/s.
