- A
Create scheduled EBS snapshots and copy them to another Region, then restore the volumes from those snapshots during recovery.
Snapshotting and cross-Region copying gives point-in-time images of EBS volumes that can be restored in the target Region.
- B
Enable EBS multi-attach to spread the workload across AZs and replicate snapshots automatically between Regions.
Why wrong: Multi-attach increases concurrent access within certain designs but does not replicate data between Regions.
- C
Use RDS read replicas in another Region and keep the analytics dataset in an RDS instance only.
Why wrong: RDS replicas address database workloads, not EBS volume snapshots for existing EC2-backed storage.
- D
Rely on instance store for durability and copy only AMIs across Regions.
Why wrong: Instance store is not reliable durable storage, and copying AMIs alone does not capture EBS volume data.
SAA-C03 Design Resilient Architectures Practice Question
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: eBS snapshots are point-in-time backups of EBS volumes.. 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 runs a stateful analytics workload on EC2 instances that use EBS volumes. The data must be restorable in another Region after a major outage, with frequent point-in-time recovery. Which approach provides the most suitable replication mechanism for the EBS-backed data?
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
Create scheduled EBS snapshots and copy them to another Region, then restore the volumes from those snapshots during recovery.
Option A is correct because scheduled EBS snapshots provide point-in-time recovery and can be copied to another Region for cross-region disaster recovery. When a major outage occurs, you can restore EBS volumes from those snapshots in the target Region, meeting the requirement for frequent restorable backups. This approach is native to AWS, cost-effective, and supports the stateful analytics workload without architectural changes.
Key principle: EBS snapshots are point-in-time backups of EBS volumes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse EBS multi-attach (which is for high availability within a single AZ) with cross-Region replication, or mistakenly think instance store can provide durable, restorable data across Regions.
Detailed technical explanation
How to think about this question
EBS snapshots are stored in Amazon S3 and are incremental, meaning only changed blocks are saved after the initial snapshot, reducing storage costs and backup time. When you copy a snapshot to another Region, AWS rehydrates the full snapshot data in the destination Region, enabling volume restoration independent of the source. For frequent point-in-time recovery, you can automate snapshot creation via Amazon Data Lifecycle Manager (DLM) and use cross-Region snapshot copy with lifecycle policies to meet RPO and RTO targets.
KKey Concepts to Remember
- EBS snapshots are point-in-time backups of EBS volumes.
- Snapshots are incremental, storing only changed blocks after the first full snapshot.
- EBS snapshots can be copied to other AWS Regions for disaster recovery.
- Volumes can be restored from snapshots in any Region where the snapshot exists.
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
EBS snapshots are point-in-time backups of EBS volumes.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
