Quick Answer
The answer is the ml.p3.2xlarge instance type. This is correct because the P3 family is specifically designed for GPU-accelerated compute, utilizing NVIDIA Tesla V100 GPUs to handle the parallel processing demands of deep learning inference. In contrast, CPU-only instances like the ml.m5, ml.c5, or ml.t2 families lack the dedicated hardware required for efficient GPU inference, making them unsuitable for models that rely on GPU computation. On the AWS Certified Machine Learning Specialty MLS-C01 exam, this question tests your ability to match workload requirements to the correct SageMaker instance type, often appearing as a straightforward discrimination between GPU and CPU families. A common trap is confusing the general-purpose or compute-optimized instances (like m5 or c5) with GPU-capable ones, so remember that any instance starting with "p" or "g" indicates GPU support. Memory tip: "P for Parallel Processing" helps you recall that P3 instances are your go-to for GPU inference.
This MLS-C01 practice question tests your understanding of machine learning implementation and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A machine learning engineer is deploying a model to an Amazon SageMaker endpoint. The model requires GPU for inference. Which instance type should be selected?
ml.p3.2xlarge
GPU instance suitable for inference.
ml.m5.large
Why wrong: General purpose CPU instance.
ml.c5.xlarge
Why wrong: Compute optimized CPU instance.
ml.r5.large
Why wrong: Memory optimized CPU instance.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ml.p3.2xlarge
Option D is correct because P3 instances (e.g., ml.p3.2xlarge) provide GPU capabilities. Options A, B, and C are CPU-only instances.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
ml.p3.2xlarge
Why this is correct
GPU instance suitable for inference.

Read the scenario before looking for a memorised answer.
ml.m5.large
Why it's wrong here
General purpose CPU instance.
ml.c5.xlarge
Why it's wrong here
Compute optimized CPU instance.
ml.r5.large
Why it's wrong here
Memory optimized CPU instance.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
