PDE Practice Question: A data science team uses Vertex AI Pipelines to…

A data science team uses Vertex AI Pipelines to automate retraining. They want to ensure that only models with performance above a threshold are deployed. Which component should they add to the pipeline?

⚠ Common exam trap

Watch out — candidates often confuse monitoring (Cloud Monitoring) or feature management (Feature Store) with the evaluation step needed to gate deployment, but only Model Evaluation provides the threshold-based conditional logic within the pipeline itself.

Correct answer & explanation

Vertex AI Model Evaluation

Vertex AI Model Evaluation provides built-in evaluation metrics and threshold-based validation that can be used as a pipeline condition to gate model deployment. By adding a Model Evaluation component, the pipeline can compare model performance against a predefined threshold and only proceed to deploy if the metrics (e.g., AUC, precision, recall) meet or exceed the required value.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Vertex AI Feature Store

    Why it's wrong here

    Used for feature management, not evaluation.

  • Vertex AI Model Evaluation

    Why this is correct

    Evaluates model and can block deployment if threshold not met.

  • Cloud Build trigger

    Why it's wrong here

    Cloud Build is for building containers.

  • Cloud Monitoring alert

    Why it's wrong here

    Alerts are reactive, not pre-deployment gates.
