Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 279 discussion

Option B mentions using Amazon S3 Glacier Flexible Retrieval, but DynamoDB doesn't natively support transitioning backups to Amazon S3 Glacier. Options C and D involve custom scripts and EventBridge rules, which add complexity and may not be as reliable or efficient as using AWS Backup for this purpose.

A for sure

Why B is wrong?

BCD, on-demand backup, manual work

A is right ans

All except A are "On-demand"

https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/BackupRestore.html Using DynamoDB with AWS Backup, you can copy your on-demand backups across AWS accounts and Regions, add cost allocation tags to on-demand backups, and transition on-demand backups to cold storage for lower costs. To use these advanced features, you must opt in to AWS Backup.

This solution satisfies the requirements in the following ways: • AWS Backup will automatically take full backups of the DynamoDB table on the schedule defined in the backup plan (the first of each month). • The lifecycle policy can transition backups to cold storage after 6 months, meeting that requirement. • Setting a 7-year retention period in the backup plan will ensure each backup is retained for 7 years as required. • AWS Backup manages the backup jobs and lifecycle policies, requiring no custom scripting or management.

Answer is A

The correct Answer is A https://aws.amazon.com/blogs/database/set-up-scheduled-backups-for-amazon-dynamodb-using-aws-backup/

A is the answer

A is the correct answe

A is the Answer can be used to create backup schedules and retention policies for DynamoDB tables

A. Create an AWS Backup plan to back up the DynamoDB table on the first day of each month. Specify a lifecycle policy that transitions the backup to cold storage after 6 months. Set the retention period for each backup to 7 years.
