Answer: Deploy an Amazon RDS proxy, directing the application to use this proxy endpoint.
The correct answer is D: Deploy an Amazon RDS proxy, directing the application to use this proxy endpoint. Amazon RDS Proxy helps to manage the database connections efficiently. It reduces the failover time by handling database failover transparently and minimizing the disruption to the application. This results in fewer moments of unavailability and less operational overhead as it handles connection pooling and other maintenance tasks automatically.
