- A
Training step
Training outputs a model artifact; caching avoids retraining if inputs unchanged.
- B
Transform step (if used)
Why wrong: Not all pipelines include a transform step; caching on Transform is possible but not required for the described scenario.
- C
Processing step (evaluation)
Processing evaluation produces metrics; caching avoids re-evaluation if inputs unchanged.
- D
Condition step
Why wrong: Condition step is a logic branch; it does not produce cacheable outputs.
- E
RegisterModel step
RegisterModel can cache if the input model artifact and metadata are unchanged, preventing redundant registration.
Question 414 of 1,000
SageMaker Pipeline Step Caching
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. 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 designing a SageMaker Pipeline that includes a training step, a processing step for evaluation, and a condition step to decide whether to register the model. The pipeline should support caching to avoid redundant runs when inputs haven't changed. Which three steps must have caching enabled? (Select THREE.)

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
✓
Training step
For caching to avoid redundant runs, the steps that produce outputs that can be reused must have caching enabled. The processing step (evaluation) and training step both generate outputs that can be cached if their inputs (code, data, hyperparameters) remain the same. The condition step does not produce outputs to cache; it just branches. The RegisterModel step typically registers metadata, but its inputs (model artifact, metrics) may be generated by previous steps; enabling caching on the RegisterModel step can also avoid re-running if the same model artifact is already registered.
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
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.
Trap categories for this question
Command / output trap
Condition step is a logic branch; it does not produce cacheable outputs.
Scenario analysis trap
Not all pipelines include a transform step; caching on Transform is possible but not required for the described scenario.
Detailed technical explanation
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 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.

Same concept, more angles

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An ML engineer is designing a SageMaker Pipeline for model training and registration. They need to ensure that the pipeline can be re-run with different datasets without manual intervention, and that the steps are only re-executed if inputs have changed. Which THREE features should they configure? (Select THREE.)
hard- A.Add a Condition step to manually check for data changes
- ✓ B.Enable step caching to reuse outputs when inputs are unchanged
- C.Configure lineage tracking to record the origin of models
- ✓ D.Use Parameterized execution to pass different values at runtime
- ✓ E.Define pipeline parameters for dataset location and hyperparameters
Why B: Pipeline parameters allow passing different inputs. Step caching reuses step outputs when inputs are identical. Using Parameterized execution is synonymous with using parameters. Lineage tracking is not for skipping steps. Condition steps are for branching, not caching. Model Registry is for versioning.
