MLS-C01 Practice Question: Machine Learning Implementation and Operations

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 company is using SageMaker Ground Truth to label images for a computer vision model. After launching the labeling job, they notice that the labeling throughput is lower than expected. What should they do to increase throughput?

A
Use a private workforce with more workers.
More workers increase labeling parallelism and throughput.
B
Change the labeling task to use a single annotator per image.
Why wrong: Single annotator may be slower; consensus requires multiple.
C
Reduce the number of workers assigned to each task.
Why wrong: Fewer workers reduce throughput.
D
Increase the time allowed for each labeling task.
Why wrong: More time per task reduces throughput.

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 private workforce with more workers.

SageMaker Ground Truth labeling throughput is primarily limited by the number of workers available to process tasks. Using a private workforce allows you to directly control and scale the number of workers, which increases parallelism and overall throughput. Public or vendor workforces have fixed capacity and may not scale as quickly, so adding more private workers is the most effective way to boost throughput.

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 confuse throughput with quality or accuracy, thinking that reducing workers or increasing time will improve speed, when in fact throughput is a direct function of parallel worker capacity.

Detailed technical explanation

How to think about this question

Ground Truth uses a task queue where workers pick up labeling tasks. Throughput is a function of the number of active workers and the average time per task. With a private workforce, you can add workers dynamically via the AWS Console or API, directly increasing the concurrency of task processing. In contrast, public or vendor workforces have a fixed pool size and may have latency in scaling. Additionally, Ground Truth supports 'consolidated labeling' where multiple annotations per image are used for quality, but throughput is still worker-limited, not annotation-count-limited.

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

An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
