I believe Answer C & D are correct: According to Wendell Odom ICND2 200-105 CCNA Guide - Chapter 7: Understanding OSPF Concepts page 175 Link-state protocols—in particular, Open Shortest Path First (OSPF) and System (IS-IS)—solved the main issues. They also came with a price: They required extra CPU and memory on routers, with more planning required from the network engineers. EIGRP solved the same problems as did link-state routing protocols, but less planning was required when implementing the network.

The answer should be D and E. Explanation: Large OSPF networks suffer: - Convergence is slow. - Topology database requires more memory. - SPF algorithm requires more processing power, CPU cycles. - A single interface change ==>> every router runs SPF again.
