Refer to the exhibit. A network designer is testing a prototype of WAN connection. All of the routers in the exhibit are configured for OSPF routing. The design requires that the path between routers A and D through ISP-A is the primary and the path through ISP-B serves as a backup. The designer notice that router A has two equal-cost paths to the LAN on router D. How can the designer correct this problem?

• issue a clock rate 2000000 interface command on S0/0/1 of router ISP-B
• change the default OSPF reference bandwidth on router A
• configure two static routes with administrative distance of 10
• use the bandwidth command to change the default bandwidth on the link to router ISP-B
