Start Collaborating Within and Across Teams to Manage Data and Models PracticeA data science team uses Vertex AI Experiments to track training runs. They want to automatically log parameters, metrics, and artifacts for all runs with minimal code changes. Which approach should they take?
Explanation: MLflow autologging, enabled via mlflow.autolog() before training and wrapped in mlflow.start_run(), automatically captures parameters, metrics, and artifacts for supported frameworks (scikit-learn, TensorFlow, PyTorch, XGBoost) with minimal code changes. Vertex AI Experiments integrates with MLflow, so runs are logged to the Vertex AI Experiments backend.
A machine learning team wants to implement champion/challenger model deployment. They have two model versions: v1 (champion) and v2 (challenger). They deploy both to the same endpoint with traffic splitting. How should they manage model versions in Vertex AI Model Registry to reflect this?
Explanation: Vertex AI Model Registry supports aliases as mutable pointers to specific model versions, so tagging v1 as 'champion' and v2 as 'challenger' creates a clear, human-readable mapping that survives version churn. Deploying both aliased versions to a single endpoint with a traffic split lets you route, say, 90% to champion and 10% to challenger while keeping the registry semantics explicit.
A machine learning engineer needs to deploy a model to an endpoint for real-time predictions. The model is registered in Vertex AI Model Registry. Which command should they use to create an endpoint and deploy the model with the alias 'champion'?
Explanation: The correct command is 'gcloud ai endpoints deploy-model' because it deploys a model from the Vertex AI Model Registry to an existing endpoint. The '--alias' flag specifies the alias 'champion' for the deployed model, which is used for traffic splitting or model versioning. This command creates a deployed model resource on the endpoint.
A team uses Vertex AI Feature Store with an online store for real-time predictions. They notice that the online store queries are taking longer than expected. Which TWO actions could improve online store performance? (Choose 2)
Explanation: Option B is correct because the online store serves feature values for real-time predictions, and reducing the number of features fetched per entity reduces the amount of data read and transferred, directly lowering query latency. Option E is correct because Vertex AI Feature Store's online serving can be backed by Bigtable, and increasing the number of Bigtable nodes raises the cluster's read throughput and reduces per-query latency under load. Option A is not appropriate because the offline store is designed for batch training and bulk export, not low-latency real-time serving. Option C is not a valid performance fix because Firestore is not the supported high-throughput online serving backend for Vertex AI Feature Store in this context. Option D is not a documented Vertex AI Feature Store online store tuning action; caching is not exposed as a simple online store performance switch.
You are configuring a Vertex AI Feature Store online store for a real-time recommendation system that requires single-digit millisecond latency and high throughput. The feature values are updated frequently. Which online store type should you use?
Explanation: The Optimized online store type in Vertex AI Feature Store is purpose-built for low-latency, high-throughput online serving of frequently updated features. It uses a serving-optimized architecture that delivers single-digit millisecond latency and scales horizontally for real-time recommendation workloads. This makes it the correct choice when both latency and throughput are critical and feature values change often.
