Which combination of steps will meet these requirements with the LEAST amount of operational overhead?
(Choose three.)
Create an AWS Backup plan with a backup rule for each of the retention requirements
Configure an AWS Backup plan to copy backups to another Region.
Create an AWS Lambda function to replicate backups to another Region and send notification if a failure occurs.
Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP_JOB_COMPLETED.
Create an Amazon Data Lifecycle Manager (Amazon DLM) snapshot lifecycle policy for each of the retention requirements.
Setup RDS snapshots on each database.
Explanations:
Creating an AWS Backup plan with rules for daily, weekly, and monthly backups allows for customized retention requirements, addressing the regulatory needs of the company. This centralizes backup management and reduces operational overhead.
Configuring an AWS Backup plan to copy backups to another Region ensures that the backups are replicated immediately, meeting the requirement for cross-region backup replication. This process is managed by AWS Backup, minimizing operational complexity.
While using an AWS Lambda function could replicate backups and send notifications, it introduces additional operational overhead compared to the built-in features of AWS Backup, which already provides these capabilities. Therefore, it is not the optimal choice for this scenario.
Adding an Amazon SNS topic to the backup plan allows for immediate notifications if a backup job fails, meeting the requirement for real-time alerts on backup failures without requiring additional custom development.
Amazon Data Lifecycle Manager (DLM) is suitable for managing EC2 instance snapshots but does not meet the full requirements for EFS and RDS backup management, making it less suitable for this comprehensive backup solution.
Setting up RDS snapshots does not meet the requirement for a unified backup solution or the need for a single source of backup status across the AWS environment. RDS snapshots would require separate management and do not provide a comprehensive backup strategy for the entire AWS environment.
