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.
A machine learning team uses Vertex AI Pipelines for model training. They want to implement a conditional step that runs additional evaluation if the model accuracy exceeds 0.9, otherwise it runs a data augmentation component. Which two Kubeflow Pipelines SDK v2 constructs can they use to achieve this? (Choose 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
✓
dsl.Else
In Kubeflow Pipelines SDK v2, `dsl.If` and `dsl.Else` are the constructs used to create conditional execution branches within a pipeline. `dsl.If` evaluates a condition (e.g., model accuracy > 0.9) and runs the enclosed steps only if true; `dsl.Else` defines the alternative branch that runs when the condition is false. This directly implements the required logic for running additional evaluation on high accuracy or data augmentation otherwise.
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 may confuse `dsl.ParallelFor` or `dsl.ExitHandler` with conditional constructs, but `dsl.If` and `dsl.Else` are the only SDK v2 constructs specifically designed for branching based on runtime conditions.
Detailed technical explanation
How to think about this question
Under the hood, `dsl.If` and `dsl.Else` in Kubeflow Pipelines SDK v2 compile to Argo Workflows' `when` conditionals, which evaluate expressions at runtime using the pipeline's intermediate representation (IR). A subtle behavior is that all branches must be defined within the same `dsl.Condition` context manager, and the condition expression must be a valid Python expression that can be serialized; using a boolean variable from a previous component's output (e.g., `accuracy > 0.9`) is typical. In real-world scenarios, this allows dynamic pipeline adaptation without redeploying the pipeline definition, such as triggering expensive evaluation only when a model meets a threshold.
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 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.
