Question

A company has an application that is using a MySQL-compatible Amazon Aurora Multi-AZ DB cluster as the database. A cross-Region read replica has been created for disaster recovery purposes. A DevOps engineer wants to automate the promotion of the replica so it becomes the primary database instance in the event of a failure. Which solution will accomplish this?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Store the Aurora endpoint in AWS Systems Manager Parameter Store. Create an Amazon EventBridge event that detects the database failure and runs an AWS Lambda function to promote the replica instance and update the end... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
