    AWS SAA-C03 · Question 61 · Domain 4.3: Database Cost Optimization

    A development team uses a relational database for a testing environment. The database is used heavily during business hours but is completely idle at night and on weekends. The team wants to minimize costs without having to manually start and stop the database.<br/><br/>Which database solution is MOST cost-effective?

    Answer options:

    A.

    Amazon RDS with a Multi-AZ deployment

    B.

    Amazon Aurora Provisioned

    C.

    Amazon Aurora Serverless

    D.

    Amazon DynamoDB

    How to approach this question

    Look for 'relational database', 'idle at night', and 'minimize costs'.

    Full Answer

    C.Amazon Aurora Serverless✓ Correct
    Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora. It automatically starts up, shuts down, and scales capacity up or down based on your application's needs. It is perfect for infrequent, intermittent, or unpredictable workloads.

    Common mistakes

    Choosing RDS and writing custom scripts to stop/start it, which violates the 'without manual intervention' (or custom scripting overhead) principle when a native solution exists.
