A company's application utilizes numerous Amazon DynamoDB tables for data storage. Auditors have identified that these tables do not adhere to the company's data protection policies. According to the company's retention policy, all data must be backed up on two specific dates each month: at midnight on the 15th and the 25th. Additionally, these backups must be retained for a period of three months. What are the appropriate steps for a security engineer to ensure compliance with these backup and retention requirements? (Select two options.)
A
Use the DynamoDB on-demand backup capability to create a backup plan. Configure a lifecycle policy to expire backups after 3 months.
B
Use AWS DataSync to create a backup plan. Add a backup rule that includes a retention period of 3 months.
C
Use AWS Backup to create a backup plan. Add a backup rule that includes a retention period of 3 months.
D
Set the backup frequency by using a cron schedule expression. Assign each DynamoDB table to the backup plan.
E
Set the backup frequency by using a rate schedule expression. Assign each DynamoDB table to the backup plan.
