SAA-C03 Question 461
Single answerA company is running a high-performance computing (HPC) workload that requires low latency and high network throughput. They need to select an EC2 instance type optimized for compute-intensive workloads and networking performance. Which instance type should they choose?
- A
R5 instances - Memory optimized
- B
C6g instances - Compute optimized
- C
T3 instances - Burstable general purpose
- D
M6i instances - General purpose
Show answer and explanation
Correct answer: B
Explanation
Compute-optimized instances, such as C6g, are designed for high-performance workloads that require significant compute power and low latency. These instances are ideal for high-performance computing (HPC) applications, as they provide enhanced networking capabilities and optimized CPU performance. Other instance types, such as memory-optimized or general-purpose instances, are not specialized for compute-intensive tasks.
- A. Incorrect.
R5 instances are memory-optimized and designed for workloads such as databases or in-memory caching. They are not suitable for compute-intensive HPC workloads.
- B. Correct.
C6g instances are compute-optimized and provide high performance for compute-heavy tasks, such as HPC, scientific modeling, and machine learning inference. They are well-suited for this use case.
- C. Incorrect.
T3 instances are burstable general-purpose instances, designed for workloads with occasional bursts of CPU usage. They are not ideal for sustained, compute-intensive HPC workloads.
- D. Incorrect.
M6i instances are general-purpose instances with a balance of compute, memory, and networking resources. While they are versatile, they are not optimized for compute-intensive workloads.
