Question #879
A financial institution must ensure that all Amazon EBS snapshots are replicated to two other AWS Regions as part of their disaster recovery plan. The solution must minimize operational complexity. Which option meets these requirements?
Use AWS Backup to create EBS snapshots and configure cross-region replication in the backup plan.
Set up an Amazon EventBridge rule to trigger an AWS Lambda function that copies snapshots to the two Regions daily.
Create an Amazon Data Lifecycle Manager policy that automatically copies snapshots to the two additional Regions.
Use Amazon S3 Cross-Region Replication to replicate the EBS snapshots stored in S3 to the other Regions.
Explanation
Option C is correct because Amazon Data Lifecycle Manager (DLM) provides a fully managed solution to automate the creation, retention, and cross-region replication of EBS snapshots. By creating a DLM policy, the financial institution can ensure snapshots are automatically copied to two other AWS Regions without manual intervention, reducing operational overhead.
Why other options are incorrect:
- A: While AWS Backup supports cross-region replication, it requires configuring a backup plan and additional steps compared to DLM's native EBS-focused automation.
- B: Using EventBridge and Lambda introduces custom code and maintenance, increasing operational complexity.
- D: EBS snapshots are stored in S3 but are not directly accessible as S3 objects, making S3 Cross-Region Replication (CRR) inapplicable.
Key Points:
- DLM is purpose-built for EBS snapshot lifecycle management.
- Managed services like DLM minimize operational tasks compared to custom solutions.
- Cross-region replication for disaster recovery is a core feature of DLM policies.
Answer
The correct answer is: C
