- A
Enable automated snapshots with a retention period of at least 1 day.
Why wrong: Automated snapshots are already configured; this step is already in place.
- B
Restore a snapshot from the secondary Region in the event of a disaster.
Restoring from a cross-Region snapshot provides DR capability.
- C
Create manual snapshots on a daily basis and copy them to another Region.
Why wrong: Automated snapshots with cross-Region copy achieve the same goal without manual effort.
- D
Configure the cluster to use multiple Availability Zones (multi-AZ) for high availability.
Multi-AZ configuration provides high availability within a Region.
- E
Configure cross-Region snapshot copy to replicate snapshots to another Region.
Cross-Region snapshot copy enables DR by replicating snapshots to another Region.
DEA-C01 Data Store Management Practice Question
This DEA-C01 practice question tests your understanding of data store management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses Amazon Redshift for its data warehouse. The cluster has multiple node types and is configured with automated snapshots. The company needs to ensure high availability and disaster recovery across AWS Regions. Which THREE actions should the company take to meet these requirements? (Choose THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Restore a snapshot from the secondary Region in the event of a disaster.
Option B is correct because restoring a snapshot from a secondary Region is the core disaster recovery action in a cross-Region DR strategy. When a primary Region fails, you can restore the cross-Region snapshot copy to a new Redshift cluster in the secondary Region, ensuring business continuity. This leverages the automated cross-Region copy configured in Option E to make the snapshot available in the DR Region.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse high availability (multi-AZ) with disaster recovery (cross-Region snapshot copy), or assume that local automated snapshots alone satisfy cross-Region DR requirements without explicitly enabling cross-Region copy.
Detailed technical explanation
How to think about this question
Amazon Redshift's cross-Region snapshot copy uses an asynchronous replication mechanism that copies snapshots from the source Region to a destination Region based on a defined retention period (1-35 days). The copied snapshot is stored in Amazon S3 in the destination Region and can be restored to a new cluster in that Region, but note that the restore time depends on cluster size and data volume, and the cluster must be in the same AWS account. In a real-world scenario, you must also ensure that the destination Region has sufficient reserved node capacity to handle the restored cluster during a disaster.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
