  The solution architect should recommend option B - Configure a backup window for the RDS DB instances for daily snapshots. Assign a snapshot retention policy of 2 years to each RDS DB instance. Use Amazon Data Lifecycle Manager (Amazon DLM) to schedule snapshot deletions. This meets the requirements of: Retaining daily backups for a minimum of 2 years. The daily snapshots captured within the backup window provide consistent, restorable backups on a daily basis. Assigning a snapshot retention policy of 2 years ensures the snapshots are retained for the required period. Using Amazon DLM allows automatically deleting snapshots older than 2 years to comply with the retention period in a cost-effective manner without manual administration. The other option of using AWS Backup vault is not as suitable since it has limitations such as 35 day maximum retention for automated backups. Option B provides a native RDS solution capable of meeting the long term 2 year retention requirements.

  I thought, for AWS exams, as a rule of thumbs, we should opt for AWS managed services?

  If not specified, AWS Backup Vault Lock will not enforce a maximum retention period. If specified, backup and copy jobs to this vault with lifecycle retention periods longer than the maximum retention period will fail. Recovery points already saved in the vault prior to the vault lock's creation are not affected. The longest maximum retention period you can specify is 36500 days (approximately 100 years).
