Answer: Create a secondary application instance in a different AWS region for failover purposes.
Option D is the correct answer. Creating a secondary application instance in a different AWS region for failover purposes is the most effective approach for ensuring data durability and availability during a disaster scenario. This approach provides geographic redundancy and allows for quick failover to the secondary instance in case of a disaster in the primary region. While options A, B, and C are important for data protection and availability, they do not provide the same level of disaster recovery capability as a multi-region deployment.
