Answer - A and B.
The AWS Documentation mentions the following:
Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud.
It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups.
It frees you to focus on your applications.
So you can give them the fast performance, high availability, security and compatibility they need.

The two correct answers regarding the benefits of AWS's Relational Database Service (RDS) are:
A. Automated patches and backups B. DB owner can resize the capacity accordingly
Here's a detailed explanation of each:
A. Automated patches and backups: AWS RDS automates many of the time-consuming database management tasks, such as applying software patches, performing backups, and monitoring the health of the database. This means that AWS manages the underlying infrastructure, allowing you to focus on your application and its data. With automated backups, you can restore your database to any point in time within the retention period. You can also take manual snapshots at any time and retain them as long as you need.
B. DB owner can resize the capacity accordingly: AWS RDS allows you to scale your database instance vertically or horizontally based on your needs. Vertical scaling involves increasing or decreasing the instance size, which increases or decreases the amount of CPU, memory, and storage available to the database. Horizontal scaling involves adding or removing replicas, which can improve performance and availability. With AWS RDS, you can scale your database without downtime or data loss, making it easier to meet the demands of your application.
C. It allows you to store unstructured data: This option is not correct. AWS RDS is designed to store structured data in a relational database, where data is organized into tables with predefined schemas. It does not support storing unstructured data such as documents, images, or videos.
D. It allows you to store NoSQL data: This option is not correct. AWS RDS is a relational database service and is not designed for storing NoSQL data. AWS provides other services such as Amazon DynamoDB and Amazon DocumentDB for NoSQL databases. These services are optimized for different use cases and offer different features than AWS RDS.
