- A
Use the dsl.CacheKey annotation to explicitly set cache keys.
Why wrong: dsl.CacheKey is not a valid KFP SDK v2 construct.
- B
Set caching_strategy.max_cache_staleness = "0s" on the component.
Setting max_cache_staleness to 0s disables caching for that component, forcing re-execution.
- C
Change the component's image tag to :latest.
Why wrong: Using :latest is not recommended and may not invalidate cache if the digest is unchanged; it also breaks reproducibility.
- D
Add a random integer parameter to the component to vary the inputs.
Why wrong: This would force re-execution but is a hack; the proper way is to disable caching.

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 building a Vertex AI pipeline using the KFP SDK v2. One component processes a large dataset and outputs a metrics artifact. You notice that the component is being cached even when the dataset changes, because the component code and image remain the same. How can you force the component to always re-execute when the dataset changes?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"always"Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.
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
✓
Set caching_strategy.max_cache_staleness = "0s" on the component.
In KFP SDK v2, caching is keyed on the component code, image digest, and all input values. If the dataset is passed as a URI string, changing the URI will invalidate the cache. If the dataset changes without a URI change, you can disable caching per component by setting caching_strategy.max_cache_staleness to 0 or using the disable_cache method.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the dsl.CacheKey annotation to explicitly set cache keys.
Why it's wrong here
dsl.CacheKey is not a valid KFP SDK v2 construct.
- ✓
Set caching_strategy.max_cache_staleness = "0s" on the component.
Why this is correct
Setting max_cache_staleness to 0s disables caching for that component, forcing re-execution.
Clue confirmation
The clue word "always" in the question point toward this answer.

Change the component's image tag to :latest.
Why it's wrong here
Using :latest is not recommended and may not invalidate cache if the digest is unchanged; it also breaks reproducibility.

Add a random integer parameter to the component to vary the inputs.
Why it's wrong here
This would force re-execution but is a hack; the proper way is to disable caching.
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 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.
