A. Writing SQL queries
B. Database schema design
C. Backing up and recovering database instances
D. Generating business reports
Answer
C. Backing up and recovering database instances
Explanation
Amazon RDS automates database administration tasks like backups, patching, and recovery, which benefits database administrators by reducing manual workload.
Amazon Relational Database Service (RDS) is a fully managed service designed to simplify database administration by automating time-consuming tasks. One of its most significant benefits is the automation of backups and recovery processes, which directly supports database reliability and availability.
Here’s why C. Backing up and recovering database instances is the correct answer:
Automated Backups
Amazon RDS automatically creates backups of your database during a specified backup window. These backups include both the database and transaction logs, enabling point-in-time recovery for up to 35 days, depending on the retention period you configure.
Point-in-Time Recovery
With automated backups, you can restore your database to any specific second within the retention period, minimizing data loss in case of accidental deletion or corruption.
Database Snapshots
RDS allows you to create manual snapshots of your database, which can be retained indefinitely and used to restore a database instance when needed.
Ease of Use
These automated features reduce the operational burden on database administrators (DBAs), allowing them to focus on higher-value tasks such as performance tuning and application optimization.
Why Other Options Are Incorrect
A. Writing SQL queries: Amazon RDS does not automate writing SQL queries. This task remains the responsibility of developers or DBAs who design and manage application logic.
B. Database schema design: While RDS supports relational databases, schema design is a manual process handled by DBAs or developers based on application needs.
D. Generating business reports: Business report generation involves data analysis tools or custom scripts, which are external to RDS functionality.
Key Takeaway
Amazon RDS automates critical administrative tasks like backups and recovery, significantly reducing the workload for DBAs and ensuring data durability and availability in cloud environments. This makes it an essential feature for organizations leveraging AWS for their relational databases.
