AWS Certified Cloud Practitioner (CLF-C02) — Question 659

A company has data lakes designed for high performance computing (HPC) workloads.

Which Amazon EC2 instance type should the company use to meet these requirements?

Answer options

• A. General purpose instances
• B. Compute optimized instances
• C. Memory optimized instances
• D. Storage optimized instances

Correct answer: B

Explanation

Compute optimized instances are ideal for compute-bound applications that benefit from high-performance processors, making them the best fit for high performance computing (HPC) workloads. Other instance families, such as memory optimized or storage optimized, are designed for memory-intensive databases or high-throughput storage needs rather than raw processing power. General purpose instances offer balanced resources but are not optimized specifically for heavy computational tasks.
