PDE Practice Question: A data scientist is using Vertex AI to train a…
A data scientist is using Vertex AI to train a model and wants to ensure that the training code and environment are reproducible. Which approach should they take?
⚠ Common exam trap
A common misconception is that using 'fixed tags' (e.g., 'v1.0') guarantees reproducibility, but tags can be reassigned to different images. A pre-built container with an exact version string or a digest ensures true immutability.
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
✓
Use Vertex AI Training with a pre-built container and specify the exact version of the framework
Specifying the exact version of a pre-built container in Vertex AI Training ensures that the same framework version, dependencies, and runtime environment are used every time the training job runs. This eliminates variability from package updates or environment drift, which is essential for reproducibility in machine learning pipelines.
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 Jupyter notebooks on Vertex AI Workbench
Why it's wrong here
Notebooks are interactive and not designed for reproducible training runs.
- ✓
Use Vertex AI Training with a pre-built container and specify the exact version of the framework
Why this is correct
Pre-built containers with version pinning ensure consistent environment and code execution.
- ✗
Use custom containers with fixed tags
Why it's wrong here
Custom containers require maintenance and may not guarantee same system dependencies.
- ✗
Use Cloud Build to train the model
Why it's wrong here
Cloud Build is for CI/CD, not optimized for training reproducibility.
