Câu 78: 300-510: Implementing Cisco Service Provider Advanced Routing Solutions (SPRI)

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut down as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

1. A. Use multiarea adjacency to extend Area 10 to the link between R2 and R3.
2. B. Create a virtual channel from R3 to R4.
3. C. Configure two OSPF processes on R2 and R3 and redistribute traffic between them.
4. D. Redistribute routes from BGP to OSPF as type E1. — đáp án hiện tại
