PDE Operationalizing machine learning models Practice Question
This PDE practice question tests your understanding of operationalizing machine learning models. 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.
Which THREE steps are required to set up a continuous training pipeline on Google Cloud using Vertex AI?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Vertex AI Pipeline to orchestrate data preprocessing, training, and model evaluation.
Option B is correct because Vertex AI Pipelines provide a managed, repeatable, and scalable way to orchestrate the entire ML workflow, including data preprocessing, training, and model evaluation. This is essential for a continuous training pipeline, as it automates the sequence of steps and ensures consistency across runs.
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.
✗
Run training on a single Compute Engine VM with a cron job.
Why it's wrong here
This lacks orchestration, evaluation, and integration with Vertex AI.
✓
Create a Vertex AI Pipeline to orchestrate data preprocessing, training, and model evaluation.
Why this is correct
Pipeline orchestrates the steps.
Related concept
Read the scenario before looking for a memorised answer.
✓
Set up a trigger (e.g., Cloud Scheduler or Cloud Build) to start training on a schedule or new data.
Why this is correct
Continuous training needs an automated trigger.
Related concept
Read the scenario before looking for a memorised answer.
✗
Manually upload the model to Vertex AI Model Registry after each training run.
Why it's wrong here
Manual steps violate continuous automation.
✓
Configure model evaluation and promotion rules (e.g., if accuracy > threshold, deploy to endpoint).
Why this is correct
Evaluation and conditional deployment are key for continuous training.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the distinction between manual, ad-hoc automation (like cron jobs) and fully managed, integrated orchestration services (like Vertex AI Pipelines), leading candidates to incorrectly select simpler but non-scalable options.
Detailed technical explanation
How to think about this question
Vertex AI Pipelines use Kubeflow Pipelines or TFX under the hood to define a directed acyclic graph (DAG) of containerized components, enabling parallel execution, caching of intermediate results, and automatic retry on failure. In a real-world scenario, a pipeline might include a data validation step using TensorFlow Data Validation (TFDV) to detect data drift before triggering retraining, ensuring model quality over time.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
