- A
Use a serverless endpoint configuration to automatically scale.
Why wrong: Serverless endpoints do not support GPU instances.
- B
Use a multi-model endpoint with a mix of CPU and GPU instances to handle variable traffic.
Multi-model endpoints allow efficient resource utilization and cost savings.
- C
Use Spot instances for the endpoint to reduce cost.
Why wrong: Spot instances can be terminated at any time, making them unsuitable for low-latency real-time inference.
- D
Provision multiple on-demand GPU instances behind a load balancer.
Why wrong: This is costly and may over-provision for normal traffic.
- E
Use Amazon SageMaker Elastic Inference to attach GPU acceleration to a CPU instance.
Elastic Inference provides GPU acceleration at a lower cost than full GPU instances.
MLA-C01 Practice Question: Deploying a machine learning model using Amazon…
This MLA-C01 practice question tests your understanding of mla-c01 exam topics. 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 company is deploying a machine learning model using Amazon SageMaker. The model is a large deep learning model that requires GPU for inference. The company expects unpredictable traffic patterns with occasional bursts. They want to minimize cost while ensuring low latency during bursts. Which TWO actions should they take? (Select TWO.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use a multi-model endpoint with a mix of CPU and GPU instances to handle variable traffic.
Option B is correct because a multi-model endpoint with a mix of CPU and GPU instances allows the company to host multiple models on the same endpoint, reducing cost by sharing underlying instances. By including GPU instances, the endpoint can handle the GPU-intensive deep learning inference for the large model, while the CPU instances can serve lighter loads or fallback traffic, ensuring low latency during unpredictable bursts without over-provisioning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse serverless endpoints with GPU support, not realizing that SageMaker serverless endpoints are CPU-only, and they may overlook that multi-model endpoints can mix instance types to balance cost and performance for bursty GPU workloads.
Detailed technical explanation
How to think about this question
SageMaker multi-model endpoints use a shared container model where the inference container loads and unloads model artifacts from Amazon EFS or S3 on demand, allowing multiple models to share the same instance. This architecture reduces cost by improving instance utilization, but it introduces a cold-start latency when a model is first loaded; however, for unpredictable bursts, the trade-off is acceptable if the model is frequently accessed. Elastic Inference (Option E) attaches a small, dedicated GPU acceleration to a CPU instance, providing GPU compute for inference without the full cost of a GPU instance, but it has limited memory and may not support very large deep learning models that require significant GPU memory.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
