   A company runs a production EC2 instance with an attached EBS volume. The instance hosts a critical application that must be recoverable within 15 minutes of a failure. The company wants to automate daily backups and retain them for 30 days. Which solution meets these requirements with the least operational overhead?

   • ACreate an AWS Backup plan with a daily schedule, a 30-day retention period, and assign the EC2 instance to the plan.
   • BCreate a manual snapshot of the EBS volume once and keep it indefinitely.
   • CEnable termination protection on the EC2 instance and rely on the instance store for data persistence.
   • DUse a cron job on the EC2 instance to run the AWS CLI create-snapshot command daily and delete snapshots older than 30 days.

   A company runs a critical application in the us-east-1 Region. The application must be recoverable within 1 hour (RTO) and with a maximum of 15 minutes of data loss (RPO) in the event of a regional failure. The company has a limited budget and wants to minimize ongoing costs. Which disaster recovery strategy best meets these requirements?

   • AWarm standby: run a scaled-down version of the application in us-west-2 and scale up in a disaster.
   • BActive/active: run the application in both regions with traffic split between them.
   • CBackup and restore: take daily snapshots and copy them to us-west-2; restore from the latest snapshot in a disaster.
   • DPilot light: replicate data to us-west-2 and keep a small core set of services running; scale up when needed.
