AWS (Amazon Web Services) Certification Practice Exam

Which of the following attributes applies to Amazon RDS?

1. It can only support SQL based databases

2. It provides automated backups and recovery solutions

3. It is exclusively for on-premise deployments

4. It requires manual scaling for performance

The correct answer is: It provides automated backups and recovery solutions

Amazon RDS, or Relational Database Service, is designed to simplify the setup, operation, and scaling of relational databases in the cloud. One of its key features is that it provides automated backups and recovery solutions. This means that RDS can automatically back up your database and retain those backups for a specified duration, which facilitates data restoration in case of loss or corruption. Additionally, automated backups can be configured to occur daily, and RDS also supports point-in-time recovery, allowing you to restore your database to any second during your retention window. The automated backup capability significantly enhances the reliability of database management, reducing the operational burden on developers and database administrators. The simplicity of restoring from backups ensures business continuity and data availability, making it a critical feature of Amazon RDS. In contrast, the other options are flawed. Amazon RDS supports multiple database engines, including SQL-based databases, but also includes support for non-relational databases through features like Aurora, which can be compatible with PostgreSQL and MySQL. RDS is a cloud service, thereby operating in the AWS cloud environment, not exclusively for on-premise deployments. Finally, Amazon RDS facilitates both vertical and horizontal scaling of resources, allowing it to automatically scale for better performance without requiring manual intervention
