Refer to the exhibit. Router R1 peers with two ISPs using static routes to get to the internet. The requirement is that R1 must prefer ISP-A under normal circumstances and failover to ISP-B if the connectivity to ISP-A is lost. The engineer observes that R1 is load balancing traffic across the two ISPs Which action resolves the issue by sending traffic to ISP-A only with failover to ISP-B?

1. A. Configure OSPF between R1. ISP-
2. B. and ISP-B for dynamic failover if any ISP link to R1 fails
3. C. Configure two static routes on R1. one pointing to ISP-A and another pointing to ISP- B with 222 admin distance
4. D. Change the bandwidth of the interface on R1 so that interface to ISP-A has a higher value than the interface to ISP-B
5. E. Configure two static routes on R1. one pointing to ISP-B with more specific routes and another pointing to ISP-A with summary routes
