A global application needs a relational database with fast local reads in multiple regions and the ability to promote a secondary region during a regional outage with minimal data loss. Which solution fits best?
A) A single RDS Multi-AZ instance in one region.
B) Amazon Aurora Global Database.
C) DynamoDB with on-demand capacity.
D) Read replicas within a single AZ.
Correct Answer: B
Explanation: Aurora Global Database replicates to secondary regions with typically sub-second lag, serves low-latency local reads, and allows promoting a secondary region during an outage. (A) is single-region. (C) DynamoDB is NoSQL, not relational. (D) provides no cross-region capability.
