- A
Use SageMaker Pipelines to run inference as part of the pipeline.
Why wrong: Pipelines are for orchestration, not primarily for batch inference.
- B
Use SageMaker Batch Transform with separate jobs for each model.
Batch Transform jobs are ephemeral and cost-effective for batch workloads.
- C
Create a single SageMaker endpoint for all models and update the model periodically.
Why wrong: A single endpoint can only host one model at a time, requiring frequent updates.
- D
Deploy each model to a separate SageMaker endpoint and delete after use.
Why wrong: Managing many endpoints increases overhead and cost.

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 team has a large number of models that need to be deployed for batch inference weekly. They want to minimize cost and management overhead. Which approach is MOST efficient?
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 SageMaker Batch Transform with separate jobs for each model.
SageMaker Batch Transform is the most efficient approach for weekly batch inference because it automatically provisions and terminates compute resources for each job, minimizing cost and management overhead. Running separate jobs for each model allows independent scaling and avoids the complexity of managing persistent endpoints or multi-model hosting for batch workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Use SageMaker Pipelines to run inference as part of the pipeline.
Why it's wrong here
Pipelines are for orchestration, not primarily for batch inference.
- ✓
Use SageMaker Batch Transform with separate jobs for each model.
Why this is correct
Batch Transform jobs are ephemeral and cost-effective for batch workloads.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the distinction between batch and real-time inference, where candidates mistakenly choose persistent endpoints (Option C or D) for batch workloads, overlooking that Batch Transform is purpose-built for cost-efficient, ephemeral batch processing.
Detailed technical explanation
How to think about this question
SageMaker Batch Transform uses a managed cluster of ML compute instances that are automatically launched, run the inference job, and then terminated, charging only for the duration of the job. This is ideal for weekly batch workloads where models are independent, as each job can use a different instance type or size without manual intervention. In contrast, persistent endpoints incur hourly costs even when idle, and multi-model endpoints require careful resource allocation to avoid contention.
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.
