Topic 1 Question 78
A company needs to keep user transaction data in an Amazon DynamoDB table. The company must retain the data for 7 years. What is the MOST operationally efficient solution that meets these requirements?
Use DynamoDB point-in-time recovery to back up the table continuously.
Use AWS Backup to create backup schedules and retention policies for the table.
Create an on-demand backup of the table by using the DynamoDB console. Store the backup in an Amazon S3 bucket. Set an S3 Lifecycle configuration for the S3 bucket.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function. Configure the Lambda function to back up the table and to store the backup in an Amazon S3 bucket. Set an S3 Lifecycle configuration for the S3 bucket.

Answer is B "Amazon DynamoDB offers two types of backups: point-in-time recovery (PITR) and on-demand backups. (==> D is not the answer) PITR is used to recover your table to any point in time in a rolling 35 day window, which is used to help customers mitigate accidental deletes or writes to their tables from bad code, malicious access, or user error. (==> A isn't the answer) On demand backups are designed for long-term archiving and retention, which is typically used to help customers meet compliance and regulatory requirements. This is the second of a series of two blog posts about using AWS Backup to set up scheduled on-demand backups for Amazon DynamoDB. Part 1 presents the steps to set up a scheduled backup for DynamoDB tables from the AWS Management Console." (==> Not the DynamoBD console and C isn't the answer either) https://aws.amazon.com/blogs/database/part-2-set-up-scheduled-backups-for-amazon-dynamodb-using-aws-backup/

The most operationally efficient solution that meets these requirements would be to use option B, which is to use AWS Backup to create backup schedules and retention policies for the table.
AWS Backup is a fully managed backup service that makes it easy to centralize and automate the backup of data across AWS resources. It allows you to create backup policies and schedules to automatically back up your DynamoDB tables on a regular basis. You can also specify retention policies to ensure that your backups are retained for the required period of time. This solution is fully automated and requires minimal maintenance, making it the most operationally efficient option.
