This SAA-C03 practice question tests your understanding of design resilient architectures. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: aurora Global Database replicates across up to five AWS Regions.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A trading dashboard uses Aurora MySQL. The company wants fast cross-Region disaster recovery with low RPO. Which architecture should be considered?
A single-AZ Aurora cluster
Why wrong: Single-AZ design does not provide cross-Region DR.
Aurora Global Database
Aurora Global Database replicates with low latency to secondary Regions and supports faster disaster recovery than snapshot-only approaches.
Manual snapshots copied monthly
Why wrong: Monthly snapshots create high RPO and slow recovery.
An ElastiCache Redis replica
Why wrong: ElastiCache is not an Aurora database DR mechanism.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Aurora Global Database
Aurora Global Database is designed for cross-Region disaster recovery with a typical RPO of 1 second and RTO of less than 1 minute, using storage-based replication that does not impact database performance. This meets the low RPO requirement for a trading dashboard, where data loss must be minimized.
Key principle: Aurora Global Database replicates across up to five AWS Regions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A single-AZ Aurora cluster
Why it's wrong here
Single-AZ design does not provide cross-Region DR.
Aurora Global Database
Why this is correct
Aurora Global Database replicates with low latency to secondary Regions and supports faster disaster recovery than snapshot-only approaches.
Related concept
Aurora Global Database replicates across up to five AWS Regions.
Manual snapshots copied monthly
Why it's wrong here
Monthly snapshots create high RPO and slow recovery.
An ElastiCache Redis replica
Why it's wrong here
ElastiCache is not an Aurora database DR mechanism.
Common exam traps
The trap here is that candidates might choose manual snapshots (Option C) thinking they are sufficient for DR, but they overlook the critical requirement of low RPO, which snapshots copied monthly cannot satisfy.
Detailed technical explanation
Aurora Global Database uses a dedicated storage layer that asynchronously replicates data from the primary Region to up to five secondary Regions with typical lag under 1 second, leveraging the same cluster volume technology. In a disaster, a secondary cluster can be promoted to primary in as little as 1 minute, and the replication is managed at the storage level, not the database engine, so no application changes are needed. This architecture is ideal for latency-sensitive applications like trading dashboards that require near-zero data loss across Regions.
Key takeaway
Aurora Global Database replicates across up to five AWS Regions.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
