Refer to the exhibit. An engineer has started to configure a router for OSPF, as shown. Which configuration must an engineer apply on the network so that area 15 traffic from R5 to R1 will prefer the route through R4?
A. Implement a sham link on the link between R3 and R2 to extend area 0 over area 15.
B. Implement a multiarea adjacency on the link between R2 and R4, with the cost manipulated to make the path through R4 preferred.
C. Place the link between R3 and R5 in a stub area to force traffic to use the route through R4.
D. Increase the cost on the link between R2 and R3 to a value higher than the link between R2 and R4, to influence the path over R3 and R4.
B. Implement a multiarea adjacency on the link between R2 and R4, with the cost manipulated to make the path through R4 preferred.
