- A
Maximum number of instances
You can limit the number of instances used by the training job.
- B
Maximum wait time in seconds
Why wrong: There is no wait time limit; jobs start as soon as resources are available.
- C
Maximum run time in seconds
You can set a maximum run time to stop the job if it runs too long.
- D
Minimum number of instances
Why wrong: There is no minimum instance limit; you can use 1 instance.
- E
Maximum number of spot instances
Why wrong: Spot instance limit is set per instance type, not per training job.

MLS-C01 Practice Question: Machine Learning Implementation and Operations
This MLS-C01 practice question tests your understanding of machine learning implementation and operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO of the following are valid configurations for SageMaker Training Job resource limits? (Select TWO.)
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
✓
Maximum number of instances
Option A is correct because SageMaker Training Jobs allow you to set a resource limit on the maximum number of instances that can be used for distributed training, which helps control costs and prevent accidental over-provisioning. Option C is correct because you can specify a maximum run time in seconds for a training job; if the job exceeds this limit, SageMaker automatically stops it, ensuring you don't incur unexpected charges.
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 'maximum run time' with 'maximum wait time' (a non-existent parameter) or assume that SageMaker supports minimum instance counts or separate spot instance limits, which are not part of the resource limit configuration.
Detailed technical explanation
How to think about this question
Under the hood, SageMaker Training Jobs use the `ResourceConfig` API parameter, which includes `InstanceCount` (the number of instances for the training job) and `VolumeSizeInGB`, but not a minimum instance count. The `StoppingCondition` parameter allows setting `MaxRuntimeInSeconds` (default 86400 seconds, i.e., 24 hours) to automatically stop a job; there is no equivalent 'wait time' parameter. In real-world scenarios, setting a maximum instance count prevents runaway costs when using large distributed training clusters, while the maximum run time is critical for long-running hyperparameter tuning jobs to avoid indefinite execution.
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.
