SAA-C03 Question 407
Single answerA company is running a high-performance database workload on Amazon EC2 instances and requires consistent high IOPS with low latency. Additionally, the solution must support a volume size of up to 16 TiB. Which Amazon EBS volume type is the most appropriate for this use case?
- A
General Purpose SSD (gp3)
- B
Provisioned IOPS SSD (io2)
- C
Provisioned IOPS SSD (io1)
- D
Throughput Optimized HDD (st1)
Show answer and explanation
Correct answer: B
Explanation
For high-performance database workloads requiring consistent high IOPS and low latency, the Provisioned IOPS SSD (io2) volume type is the most appropriate choice. It is specifically designed for such use cases, offering higher reliability and durability compared to io1, and it supports the required volume size of up to 16 TiB. Other volume types like gp3 or st1 are not optimized for such demanding workloads.
- A. Incorrect.
General Purpose SSD (gp3) is designed for a balance of price and performance and supports high IOPS, but it is not specifically optimized for sustained high-performance workloads like io2.
- B. Correct.
Provisioned IOPS SSD (io2) is specifically designed for high-performance, low-latency applications such as databases. It supports up to 16 TiB volume size and provides high durability and reliability, making it the most suitable choice for this scenario.
- C. Incorrect.
Provisioned IOPS SSD (io1) is similar to io2 but provides slightly less durability and features. While it supports high IOPS, io2 is preferred for critical workloads due to its improved features over io1.
- D. Incorrect.
Throughput Optimized HDD (st1) is designed for large, sequential workloads such as big data and log processing. It is not suitable for low-latency or high-performance database workloads.
