- A
Store intermediate data in Cloud Storage with unique run IDs.
Unique paths prevent collisions and support idempotency.
- B
Pass large datasets between components as serialized in-memory objects.
Why wrong: In-memory passing is not recommended; use GCS URIs.
- C
Monitor feature distributions in training data vs. serving data to detect skew.
Skew detection is critical for maintaining model performance.
- D
Use the same random seed for every run to ensure reproducibility.
Why wrong: Reproducibility is good, but not specifically for skew detection; also, random seeds may not be the primary method.
- E
Ensure each component produces deterministic outputs given the same inputs.
Idempotency requires deterministic components.

PMLE Automating and Orchestrating ML Pipelines Practice Question
This PMLE practice question tests your understanding of automating and orchestrating ml pipelines. 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.
You are tasked with building a robust ML pipeline that must be idempotent and handle data skew between training and serving. Which three practices should you implement?
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
✓
Store intermediate data in Cloud Storage with unique run IDs.
Idempotent components ensure the same inputs produce the same outputs. Passing data via GCS URIs is a best practice. Skew detection should compare training data distribution with serving data. Using unique run IDs for outputs ensures idempotency. Avoiding in-memory data passing is important for large datasets.
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.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
