SAP-C02 Question 438
Select 3A company operates a mission-critical application on Amazon EC2 instances with data stored in Amazon EBS volumes. The company wants to implement a backup strategy that ensures point-in-time recovery, adheres to compliance requirements for data retention, and is cost-effective. Which combination of actions should you take to meet these requirements?
- A
Use AWS Backup to create and manage backup plans for the EBS volumes.
- B
Schedule Amazon EBS snapshots manually during off-peak hours to minimize API costs.
- C
Enable Amazon Data Lifecycle Manager (DLM) policies to automate EBS snapshot creation and deletion.
- D
Copy EBS snapshots to a different AWS Region for disaster recovery.
- E
Increase the size of EBS volumes to store backups locally on the same volume.
Show answer and explanation
Correct answers: A, C, D
Explanation
The combination of AWS Backup, DLM, and cross-Region snapshot copying provides a cost-effective, automated, and compliant backup strategy. AWS Backup centralizes backup management, DLM automates snapshot creation and retention, and cross-Region snapshot copying ensures disaster recovery readiness. Manual backup methods and storing backups on the same volume are inefficient and do not adhere to best practices for durability and compliance.
- A. Correct.
Correct. AWS Backup provides centralized backup management for EBS volumes, allowing you to create backup plans that ensure compliance and point-in-time recovery while automating the retention process.
- B. Incorrect.
Incorrect. While manual snapshot scheduling can work, it is not scalable or efficient for compliance requirements. Automated solutions like AWS Backup or DLM are preferred for production environments.
- C. Correct.
Correct. Amazon Data Lifecycle Manager (DLM) allows automated scheduling and retention of snapshots, which is cost-effective and ensures compliance requirements are met.
- D. Correct.
Correct. Copying EBS snapshots to another Region is a best practice for disaster recovery, ensuring data is available in case of a regional outage.
- E. Incorrect.
Incorrect. Increasing the size of EBS volumes to store backups is not a recommended practice. Backups should be stored independently of the original data to ensure durability and recovery in case of data corruption or volume failure.
