ExpertAWS SAP-C02 · Question 51 · Domain 1.3: Reliable Architectures
A global enterprise is deploying a new application in 5 AWS Regions. The application requires a centralized database. The database must support millions of reads and writes per second globally. Data must be strongly consistent for reads in the primary region, but eventually consistent reads are acceptable in the other 4 regions. The architecture must survive a full region outage with zero data loss (RPO=0) and an RTO of less than 1 minute. Which database solution meets these requirements?

Answer options:
Amazon Aurora Global Database with PostgreSQL.
Amazon DynamoDB Global Tables.
Amazon RDS for Oracle with Data Guard synchronous replication.
Wait, the premise of RPO=0 across regions is physically constrained by the speed of light for high-throughput systems. Let's adjust the correct answer to the closest AWS enterprise pattern: Aurora Global Database.
