Your customer is deploying a data center with redundant connections for WAN services through ISP-1 and ISP-2. Your customer has decided to deploy an active/passive Internet connection uplink model and pay-per-use for a passive connection associated with ISP-2. The customer wants to ensure limited use of the connection through ISP-2. Which two actions would you perform to meet the objective? (Choose two )

A. Extend the AS Path length on the prefix advertised to ISP-1 to influence ingress traffic to enter through ISP-1.

B. Use MED and Origin to direct northbound traffic flows out ISP-1

C. Extend the AS Path length on the prefix advertised to ISP-2 to influence ingress traffic to enter through ISP-1.

D. Use Local Preference to direct northbound traffic flows out ISP-1

Exhibit: Within ISP E, R1 is load-balancing traffic destined to ISP D over the R1-R2-R5 and R1-R4-R5 paths. At some point, a link degradation event occurs in the network as shown in the exhibit. You want R1 to rapidly learn of the path failure.

A. Adjust the OSPF hello timer to a subsecond value between R1 and R4.

B. Enable Bidirectional Forwarding Detection between R1 and R4.

C. Enable Bidirectional Forwarding Detection between R4 and R5.

D. Adjust the OSPF hello timer to a subsecond value between R4 and R5.
