SAA-C03 Question 406
Single answerA company is running a batch processing workload that requires high throughput for large, sequential data transfers. The workload is not latency-sensitive, and cost optimization is a key priority. Which Amazon EBS volume type is the MOST suitable for this use case?
- A
General Purpose SSD (gp3)
- B
Provisioned IOPS SSD (io2)
- C
Throughput Optimized HDD (st1)
- D
Cold HDD (sc1)
Show answer and explanation
Correct answer: C
Explanation
The workload described in the scenario requires high throughput for large, sequential data transfers, which is a key characteristic of Throughput Optimized HDD (st1) volumes. Additionally, the cost-sensitive nature of the workload makes st1 a better fit than SSD volumes, which are generally more expensive. Cold HDD (sc1) is not suitable due to its lower performance characteristics, even though it is cost-effective.
- A. Incorrect.
General Purpose SSD (gp3) is designed for a balance of price and performance and is typically used for latency-sensitive workloads. It is not optimized for high throughput of large, sequential data transfers.
- B. Incorrect.
Provisioned IOPS SSD (io2) is designed for applications requiring high IOPS and low latency, making it too expensive and not suitable for a cost-sensitive, throughput-focused workload.
- C. Correct.
Throughput Optimized HDD (st1) is specifically designed for high throughput of large, sequential workloads such as batch processing. It is cost-effective and a good fit for this use case.
- D. Incorrect.
Cold HDD (sc1) is the lowest-cost EBS volume type designed for infrequent access. While it is cost-effective, it is not suitable for workloads requiring high throughput.
