Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 979 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 979
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is developing a new application that uses a relational database to store user data and application configurations. The company expects the application to have steady user growth. The company expects the database usage to be variable and read-heavy, with occasional writes.

The company wants to cost-optimize the database solution. The company wants to use an AWS managed database solution that will provide the necessary performance.

Which solution will meet these requirements MOST cost-effectively?

  • A. Deploy the database on Amazon RDS. Use Provisioned IOPS SSD storage to ensure consistent performance for read and write operations.
  • B. Deploy the database on Amazon Aurora Serverless to automatically scale the database capacity based on actual usage to accommodate the workload.
  • C. Deploy the database on Amazon DynamoDB. Use on-demand capacity mode to automatically scale throughput to accommodate the workload.
  • D. Deploy the database on Amazon RDS. Use magnetic storage and use read replicas to accommodate the workload.

Selected Answer: B
A - You’d pay for high performance even when you don’t need it B - You only pay for the database capacity you use, making it cost-efficient for unpredictable traffic. C - DynamoDB is not even a relational database. D - Magnetic disks have significantly slower IOPS compared to SSDs. P.S. In the AWS context, magnetic storage refers to standard storage volumes (previously called "Magnetic" volumes) in EBS. It offers lower performance compared to modern SSD storage but is cheaper per GB.

Selected Answer: B
Option D is out: Aurora data is stored in the cluster volume, which is a single, virtual volume that uses solid state drives (SSDs). So option B is correct
