SAA-C03 Question 366
Single answerA company is planning to deploy a high-performance database application on AWS. The database requires low-latency storage with at least 20,000 IOPS and 1 TB of storage capacity. What is the most cost-effective storage option to meet the business requirements?
- A
Amazon EBS General Purpose SSD (gp3) with provisioned IOPS
- B
Amazon EBS Provisioned IOPS SSD (io2)
- C
Amazon EBS Magnetic volumes
- D
Amazon S3 Standard storage class
Show answer and explanation
Correct answer: A
Explanation
The correct answer is Amazon EBS Provisioned IOPS SSD (io2) because it is specifically designed to handle high IOPS workloads (up to 64,000 IOPS) and offers low-latency storage. While gp3 is a cost-effective option for many use cases, it cannot meet the required 20,000 IOPS in this scenario. Magnetic volumes and S3 are not suitable for high-performance database applications.
- A. Correct.
Amazon EBS General Purpose SSD (gp3) is a cost-effective option that allows you to provision up to 16,000 IOPS and 1,000 MB/s throughput. However, for 20,000 IOPS, this option does not meet the requirements.
- B. Incorrect.
Amazon EBS Provisioned IOPS SSD (io2) is designed for high-performance, low-latency applications. It supports up to 64,000 IOPS and meets the 20,000 IOPS requirement for the database. Although more expensive than gp3, it is the most appropriate and cost-effective option for this workload.
- C. Incorrect.
Amazon EBS Magnetic volumes are legacy storage options with low performance and are not suitable for high IOPS requirements.
- D. Incorrect.
Amazon S3 Standard is an object storage service and is not designed for use as a low-latency, high-performance database storage solution.
