SOA-C02 Question 100
Select 3A company stores critical business data in Amazon EBS volumes attached to EC2 instances. The SysOps Administrator is tasked with implementing a backup and restore strategy that minimizes data loss and ensures quick recovery in case of failure. Which of the following steps should the administrator take to achieve this?
- A
Use AWS Backup to create scheduled backups of the EBS volumes.
- B
Enable Amazon S3 Versioning for the EBS volumes to maintain version history of the data.
- C
Create Amazon EBS Snapshots regularly and replicate them to another AWS Region.
- D
Use Amazon Data Lifecycle Manager (DLM) to automate the creation and retention of EBS Snapshots.
- E
Configure Amazon S3 Glacier Vault Lock for the EBS volumes to implement immutable backups.
Show answer and explanation
Correct answers: A, C, D
Explanation
To implement a reliable backup and restore strategy for EBS volumes, the SysOps Administrator should use AWS Backup for scheduled backups, leverage EBS Snapshots for point-in-time recovery, and replicate snapshots to another region for disaster recovery. Automating snapshot management with Amazon DLM further streamlines the process. Solutions like S3 Versioning and S3 Glacier Vault Lock are specific to S3 storage and not applicable to EBS.
- A. Correct.
Correct: AWS Backup is a managed service that supports automated, scheduled backups for EBS volumes, which helps implement a robust backup strategy.
- B. Incorrect.
Incorrect: Amazon S3 Versioning is specific to S3 buckets and cannot be applied to EBS volumes. This option is irrelevant in the context of EBS.
- C. Correct.
Correct: Creating EBS Snapshots and replicating them to another region ensures that backups are available in case of regional failures, providing greater resilience.
- D. Correct.
Correct: Amazon Data Lifecycle Manager (DLM) is a recommended approach to automate the creation and management of EBS Snapshots, reducing manual effort and ensuring consistent backups.
- E. Incorrect.
Incorrect: Amazon S3 Glacier Vault Lock is a compliance-oriented feature for S3 Glacier and doesn't apply to EBS volumes. It is not relevant to this scenario.
