A data science team is running machine learning training jobs on Amazon EC2. The jobs take days to complete. The team wants to significantly reduce the training time by using instances equipped with specialized hardware designed specifically for machine learning acceleration.<br/><br/>Which EC2 instance family should a solutions architect recommend?

Answer options:

C instances (Compute Optimized)

R instances (Memory Optimized)

P or G instances (Accelerated Computing)

I instances (Storage Optimized)

How to approach this question

Match the workload (Machine Learning) to the correct EC2 instance family.

Full Answer

C.P or G instances (Accelerated Computing)✓ Correct

P or G instances (Accelerated Computing)

Accelerated computing instances (P, G, Inf families) use hardware accelerators like GPUs or AWS Inferentia to perform complex calculations required for machine learning much faster than standard CPUs.

Common mistakes

Choosing Compute Optimized (C) instances, missing the need for GPU acceleration in ML training.
