Amazon RDS Automated Backups

5 minutes 5 Questions

Amazon RDS Automated Backups is a fully managed backup service that allows you to automatically create and store database backups. It enables point-in-time recovery, which allows you to restore your database to any second during your retention period, up to the last five minutes. With this feature, you can ensure data durability and simplify compliance with regulatory requirements. Automated Backups also enables fast and efficient disaster recovery by leveraging AWS infrastructure and services, such as Amazon S3 for storage and Amazon CloudWatch for monitoring. In case of a database failure, you can quickly create a new DB instance from the most recent backup, minimizing downtime and data loss.

Question 1

Your application is running with an Amazon RDS instance, and the Automated Backups retention period is set to 7 days. Which of the below scenarios can be achieved with this configuration?

Restore the instance to a specific point 1 year ago Restore the instance to a specific point 10 days ago Restore the instance to the latest possible data available Restore the instance to a specific point within the last 7 days

Correct Answer: Restore the instance to a specific point within the last 7 days

With a retention period of 7 days, you can restore the instance to a specific point within the last 7 days. Any other choices that mention restoring beyond the retention period, to the latest data or to the future are invalid.

Question 2

A company has an RDS instance where automated backups are enabled with a 5-day retention period. They have received a 30-day data retention requirement. What should they do to meet this requirement?

Increase the retention period of automated backups to 30 days Export the data to Amazon S3 on a daily basis and retain it for 30 days Take a manual snapshot every 5 days and maintain a rolling 30-day retention period Manually create daily snapshots and retain them for 30 days

Correct Answer: Increase the retention period of automated backups to 30 days

Increasing the retention period of the automated backups to 30 days is the easiest and most efficient way to meet the requirement. Other choices either rely on manual snapshots, the export of data or maintaining multiple RDS instances, which would be inefficient and labor-intensive.

Question 3

A company has an Amazon RDS instance running in production with automated backups enabled. They want to enhance the security of automated backup data. What should they do?

Enable Transparent Data Encryption (TDE) for the RDS instance Encrypt automated back up data by creating IAM policies Store automated backup data in encrypted S3 storage Modify the RDS instance to change the encrypted Automated Backup setting

Correct Answer: Enable Transparent Data Encryption (TDE) for the RDS instance

Enabling Transparent Data Encryption (TDE) will enhance the security of automated backup data as TDE encrypts data at rest including automated backups. Other choices are either incorrect or unrelated to RDS automated backups security.
