A company's primary Amazon RDS database instance experienced a hardware failure. The database was configured with Multi-AZ deployments. What happens next?

Answer options:

The application must be manually updated with the standby instance's IP address.

Amazon RDS automatically fails over to the standby instance without changing the database endpoint.

A Read Replica is automatically promoted to become the new primary instance.

The database is restored from the latest automated snapshot.

How to approach this question

Understand how RDS Multi-AZ failover works.

Full Answer

B.Amazon RDS automatically fails over to the standby instance without changing the database endpoint.✓ Correct

In an RDS Multi-AZ deployment, AWS automatically provisions and maintains a synchronous standby replica. During a failure, RDS automatically updates the DNS record of the DB instance to point to the standby.

Common mistakes
