A global financial application requires a relational database. The database must span multiple AWS Regions to provide local read performance for users worldwide. In the event of a regional outage, the database must fail over to another region with an RPO of less than 1 second and an RTO of less than 1 minute. Which solution meets these requirements?

Answer options:

Amazon RDS Multi-AZ

Amazon RDS with Cross-Region Read Replicas

Amazon Aurora Global Database

Amazon DynamoDB Global Tables

How to approach this question

Match 'relational database', 'cross-region', and 'sub-second RPO' to Aurora Global Database.

Full Answer

C.Amazon Aurora Global Database✓ Correct

Amazon Aurora Global Database is designed for globally distributed applications, allowing a single Amazon Aurora database to span multiple AWS Regions. It replicates data with no impact on database performance, enables fast local reads, and provides disaster recovery from region-wide outages.

Common mistakes

Choosing DynamoDB Global Tables, missing the 'relational database' requirement.
