This DEA-C01 practice question tests your understanding of data store management. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 data engineer is designing a multi-Region disaster recovery solution for an Amazon DynamoDB table. The table must be available in a secondary Region with minimal data loss and automatic failover. Which feature should be used?
DynamoDB on-demand backup and restore in the secondary Region
Why wrong: Backup and restore is manual and not real-time.
DynamoDB global tables
Global tables replicate data across Regions and support automatic failover.
DynamoDB point-in-time recovery (PITR)
Why wrong: PITR allows restore to any point in time but is single-Region.
DynamoDB cross-Region snapshot export to S3
Why wrong: Export to S3 is not automatic failover.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
DynamoDB global tables
DynamoDB global tables provide a fully managed, multi-Region, multi-active database solution that replicates data automatically across selected AWS Regions. This ensures automatic failover with eventual consistency and minimal data loss, meeting the disaster recovery requirements for high availability and automatic failover without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
DynamoDB on-demand backup and restore in the secondary Region
Why it's wrong here
Backup and restore is manual and not real-time.
DynamoDB global tables
Why this is correct
Global tables replicate data across Regions and support automatic failover.
Related concept
Read the scenario before looking for a memorised answer.
DynamoDB point-in-time recovery (PITR)
Why it's wrong here
PITR allows restore to any point in time but is single-Region.
DynamoDB cross-Region snapshot export to S3
Why it's wrong here
Export to S3 is not automatic failover.
Common exam traps
The trap here is that candidates often confuse point-in-time recovery (PITR) with cross-Region disaster recovery, but PITR is a single-Region feature that does not provide automatic failover or multi-Region replication.
Detailed technical explanation
DynamoDB global tables use a last-writer-wins (LWW) conflict resolution mechanism based on the timestamp of each write, ensuring eventual consistency across Regions. Under the hood, each replica table in a global table set uses the same table name and primary key schema, and DynamoDB Streams capture changes to replicate them asynchronously to other Regions, typically within seconds. In a real-world scenario, if a primary Region becomes unavailable, application traffic can be redirected to a secondary Region where the data is already available, with the trade-off of potential last-millisecond data loss due to the asynchronous replication lag.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
