A team wants to retrain a model weekly using new data stored in BigQuery. They want to minimize manual effort. Which approach should they use?
⚠ Common exam trap
Google Cloud often tests the distinction between simple scheduling (Cloud Scheduler + Cloud Function) and full ML orchestration (Vertex AI Pipelines), where candidates mistakenly choose the simpler option without considering the need for a managed, scalable ML workflow.
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
✓
Create a Vertex AI Pipeline scheduled via Cloud Scheduler
Vertex AI Pipelines allow you to define a repeatable, automated ML workflow that can be triggered on a schedule via Cloud Scheduler. This minimizes manual effort by handling data extraction from BigQuery, model retraining, and deployment without human intervention, while also providing versioning and monitoring capabilities.
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 Cloud Scheduler to trigger a Cloud Function that retrains
Why it's wrong here
Cloud Function may not handle full pipeline.
- ✗
Retrain manually in a notebook each week
Why it's wrong here
Manual effort required.
- ✗
Use Cloud Composer to orchestrate retraining
Why it's wrong here
Overkill for simple schedule.
- ✓
Create a Vertex AI Pipeline scheduled via Cloud Scheduler
Why this is correct
Pipelines automate retraining end-to-end.
