SAP-C02 Question 437
Select 2Your organization manages a fleet of Amazon EC2 instances hosting critical applications. You are tasked with designing a backup strategy to ensure data durability and recovery in case of hardware failure or accidental deletion. The solution must minimize costs while adhering to best practices for backups. Which combination of actions should you take?
- A
Schedule regular snapshots of the Amazon EBS volumes attached to the EC2 instances.
- B
Enable Amazon S3 Versioning for all objects stored on attached EBS volumes.
- C
Store Amazon EBS snapshots in Amazon S3 Glacier for long-term archival storage.
- D
Use AWS Backup to centralize and automate backup scheduling for the Amazon EBS volumes.
- E
Configure Amazon EBS volumes with a RAID 0 setup to improve performance and durability.
Show answer and explanation
Correct answers: A, D
Explanation
To ensure a robust and cost-effective backup solution for Amazon EC2 instances, regular snapshots of Amazon EBS volumes are essential as they provide a reliable way to restore data. AWS Backup further simplifies and automates the backup process, ensuring that scheduling and compliance requirements are met. Other options, such as enabling Amazon S3 Versioning or using RAID 0, are either irrelevant to the scenario or do not meet the requirements for durability and recovery.
- A. Correct.
Scheduling regular snapshots of Amazon EBS volumes is a recommended backup practice. Snapshots provide a point-in-time backup of the volumes and can be used to restore data in case of failure or deletion.
- B. Incorrect.
Amazon S3 Versioning is specific to objects stored in Amazon S3 buckets, not Amazon EBS volumes. It is not applicable to this scenario.
- C. Incorrect.
While Amazon EBS snapshots are stored in Amazon S3 by default, you cannot directly store them in Amazon S3 Glacier. Snapshots are automatically managed by AWS, and they are not intended to be moved to Glacier manually.
- D. Correct.
AWS Backup is a managed service that simplifies and centralizes backup scheduling, making it a best practice for automating EBS volume backups and ensuring compliance.
- E. Incorrect.
Configuring Amazon EBS volumes with RAID 0 improves performance but does not enhance durability. RAID 0 offers no fault tolerance and is not a backup solution.
