Question

A company is running a critical application that uses an Amazon RDS for MySQL database to store data. The RDS DB instance is deployed in Multi-AZ mode. A recent RDS database failover test caused a 40-second outage to the application. A solutions architect needs to design a solution to reduce the outage time to less than 20 seconds. Which combination of steps should the solutions architect take to meet these requirements? (Choose three.)

Accepted Answer

Correct answer: C, D, E. The correct answer is C, D, E. Option C: Use RDS Proxy in front of the database. Option D: Migrate the database to Amazon Aurora MySQL. Option E: Create an Amazon Aurora Replica. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. Amazon RDS Proxy pools and shares database connections to improve scalability and resilience. Amazon RDS is a managed relational database that handles patching, backups and failover. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
