ISC2 Systems Security Certified Practitioner (SSCP) Practice Question
Your organization hosts a Windows application on a single Amazon EC2 instance backed by a 2-TiB gp3 volume. Security policy mandates the ability to restore the virtual machine to any point in the last 24 hours within minutes, and to retain 30 daily backups in a separate Region for disaster recovery. Which solution meets the requirements while minimizing operational overhead?
Configure EC2 Image Builder to generate a new AMI every hour and share the AMI to another Region, retaining the last 30 images.
Install third-party backup software on the instance to stream compressed backups to Amazon S3 Glacier in another Region on an hourly schedule.
Use AWS Backup to create hourly incremental EBS snapshots, enable cross-Region copy with a 30-day retention policy, and activate Fast Snapshot Restore on the latest snapshots.
Migrate the data to Amazon EFS and use AWS DataSync to replicate the file system hourly to another Region while keeping 30 versions.
Using AWS Backup to schedule hourly, incremental Amazon EBS snapshots satisfies the 24-hour point-in-time recovery window without moving the workload or installing additional agents. Enabling cross-Region copy in the backup plan stores each snapshot in a second Region, and the service's retention policies keep exactly 30 daily copies. Activating Fast Snapshot Restore on the most recent backups allows new volumes to be mounted immediately, meeting the requirement to recover within minutes. Creating AMIs every hour produces additional, unnecessary images and does not guarantee fast restoration. Third-party software that streams data to Amazon S3 Glacier offers inexpensive storage but cannot restore a 2-TiB boot volume quickly. Replicating the workload to Amazon EFS changes the storage layer and still requires an EC2 recovery step, adding complexity and overhead.
