AWS Certified Solutions Architect – Associate (SAA-C02) — Question 87

A company needs to implement a relational database with a multi-Region disaster recovery Recovery Point Objective (RPO) of 1 second and a Recovery Time
Objective (RTO) of 1 minute.
Which AWS solution can achieve this?

Answer options

• A. Amazon Aurora Global Database
• B. Amazon DynamoDB global tables
• C. Amazon RDS for MySQL with Multi-AZ enabled
• D. Amazon RDS for MySQL with a cross-Region snapshot copy

Correct answer: A

Explanation

Amazon Aurora Global Database is specifically designed for global applications, providing low-latency reads and fast recovery capabilities, thus meeting the 1 second RPO and 1 minute RTO. In contrast, Amazon DynamoDB global tables is a NoSQL service, which does not align with the need for a relational database. Amazon RDS for MySQL with Multi-AZ offers high availability but does not provide the required cross-Region capabilities, and cross-Region snapshots do not meet the low RPO requirement.
