Topic 1 Question 997
A company is launching a new application that requires a structured database to store user profiles, application settings, and transactional data. The database must be scalable with application traffic and must offer backups.
Which solution will meet these requirements MOST cost-effectively?
Deploy a self-managed database on Amazon EC2 instances by using open source software. Use Spot Instances for cost optimization. Configure automated backups to Amazon S3.
Use Amazon RDS. Use on-demand capacity mode for the database with General Purpose SSD storage. Configure automatic backups with a retention period of 7 days.
Use Amazon Aurora Serverless for the database. Use serverless capacity scaling. Configure automated backups to Amazon S3.
Deploy a self-managed NoSQL database on Amazon EC2 instances. Use Reserved Instances for cost optimization. Configure automated backups directly to Amazon S3 Glacier Flexible Retrieval.

A - Spot Instance is never a good idea for databases. These instances can be terminated with little notice, while databases are almost always persistent workloads. B - On-Demand Capacity is suitable for steady or predictable workloads, but not as cost-efficient as Aurora Serverless for spiky or unpredictable workloads. C - Aurora Serverless is a fully managed relational database that scales automatically with traffic. Automated Backups is also integrated with Aurora. Good! D - We need a structured database, not NoSQL database.
