A retail company wants to build a product recommendation engine using their historical purchase data stored in BigQuery without writing complex ML code.

Which Google Cloud approach enables this?

A) BigQuery ML to train a recommendation model using SQL directly on the data in BigQuery
B) Exporting data to CSV and training a model on a local laptop
C) Using Cloud Functions to implement recommendation logic with hardcoded rules
D) Building a custom TensorFlow model from scratch on Compute Engine without evaluating simpler options

 

Correct answers: A – Explanation:
BigQuery ML allows training ML models using SQL directly in BigQuery, ideal for teams with SQL skills and data already in BigQuery. Local laptop training does not scale. Hardcoded rules are not ML. Custom TensorFlow from scratch is more complex when BigQuery ML can handle the use case.

A data science team has developed a TensorFlow model in a Jupyter notebook and needs to scale training to use multiple GPUs on Google Cloud.

Which Google Cloud service should they use?

A) Vertex AI Training with custom training jobs configured for multi-GPU instances
B) Cloud Functions with GPU support
C) A single Compute Engine CPU-only VM
D) Cloud SQL for storing model weights during training

 

Correct answers: A – Explanation:
Vertex AI Training provides managed custom training with multi-GPU and distributed training support. Cloud Functions do not support GPUs. CPU-only VMs cannot accelerate training. Cloud SQL stores relational data, not training infrastructure.

A trained ML model needs to be deployed as a real-time prediction API that auto-scales based on request volume.

Which Google Cloud service provides managed model serving?

A) Vertex AI Endpoints for managed, auto-scaling online prediction serving
B) Cloud Storage for hosting the model file with a direct download link
C) Cloud SQL for storing predictions in a lookup table
D) A manually managed Flask application on a single Compute Engine VM

 

Correct answers: A – Explanation:
Vertex AI Endpoints provide managed model serving with auto-scaling, versioning, and traffic splitting. Cloud Storage hosts files, not serving APIs. Cloud SQL lookup tables do not provide real-time inference. Manual Flask apps do not auto-scale or provide managed infrastructure.

A company wants to use a large language model to generate customer support responses based on their product documentation, without training a model from scratch.

Which Google Cloud approach should they use?

A) Vertex AI with foundation models (PaLM/Gemini) using grounding or retrieval-augmented generation with their product documentation
B) Training a custom GPT model from scratch using only their documentation
C) Using Cloud Natural Language API for text generation
D) Building a rule-based chatbot without any ML

 

Correct answers: A – Explanation:
Vertex AI foundation models with grounding or RAG leverage pre-trained LLMs augmented with company-specific documentation. Training from scratch is time-consuming and expensive. Natural Language API analyzes text, not generates it. Rule-based chatbots lack natural language understanding.

An ML engineer needs to track experiments, compare model metrics, and manage model versions throughout the ML lifecycle.

Which Vertex AI feature supports experiment tracking and model management?

A) Vertex AI Experiments for tracking runs and Vertex AI Model Registry for versioning and managing models
B) A shared spreadsheet for logging experiment results manually
C) Cloud Storage folders organized by experiment date
D) Git commits tagged with model performance metrics

 

Correct answers: A – Explanation:
Vertex AI Experiments and Model Registry provide integrated experiment tracking with metric comparison and model version management. Spreadsheets do not integrate with the ML platform. Cloud Storage folders lack metadata and comparison features. Git tags are for code versioning, not ML experiment management.

A model deployed to production starts showing degraded accuracy over time as user behavior patterns change.

What should the ML engineer implement to detect and address this?

A) Vertex AI Model Monitoring for data drift and prediction drift detection, with automated retraining pipelines triggered by drift alerts
B) Ignoring the accuracy degradation since the model was accurate at deployment
C) Increasing the serving infrastructure to handle more requests
D) Manually checking model accuracy once a year

 

Correct answers: A – Explanation:
Model Monitoring detects data and prediction drift, and automated retraining addresses accuracy degradation proactively. Ignoring degradation leads to poor user experience. More infrastructure does not fix model accuracy. Annual checks miss ongoing drift.

A healthcare company wants to build an ML model but must ensure the model’s predictions are explainable and do not exhibit bias across demographic groups.

Which Vertex AI capabilities support responsible AI?

A) Vertex AI Explainable AI for feature attributions and Vertex AI Fairness indicators for bias detection
B) Deploying the model without any bias evaluation
C) Using only the most complex model architecture for maximum accuracy
D) Building a custom TensorFlow model from scratch on Compute Engine without evaluating simpler options

 

Correct answers: A – Explanation:
Explainable AI provides feature attributions for understanding predictions, and Fairness indicators evaluate bias across groups. Skipping bias evaluation risks harm. Complex models may be less explainable. Restricting access does not address bias or explainability.

An ML engineer needs to create a repeatable ML pipeline that automates data preprocessing, model training, evaluation, and conditional deployment.

Which Google Cloud service should they use?

A) Vertex AI Pipelines using Kubeflow Pipelines SDK for orchestrating end-to-end ML workflows
B) A series of Cloud Functions chained together with Pub/Sub triggers
C) Manual execution of each step in separate Jupyter notebooks
D) Cloud Composer for ML pipeline orchestration only

 

Correct answers: A – Explanation:
BigQuery ML allows training ML models using SQL directly in BigQuery, ideal for teams with SQL skills and data already in BigQuery. Local laptop training does not scale. Hardcoded rules are not ML. Custom TensorFlow from scratch is more complex when BigQuery ML can handle the use case.

A company needs to build a custom image classification model using their labeled dataset of 100,000 product images but has limited ML expertise on their team.

Which Vertex AI feature enables this without extensive ML coding?

A) Vertex AI AutoML Vision for training a custom image classification model with a labeled dataset and no coding required
B) Writing a custom CNN architecture from scratch in TensorFlow
C) Using Cloud Vision API which only provides pre-built labels, not custom models
D) Hiring a team of ML researchers before starting the project

 

Correct answers: A – Explanation:
AutoML Vision trains custom image models from labeled data without requiring ML expertise. Custom CNN requires significant ML knowledge. Cloud Vision API provides pre-built classification, not custom model training. Hiring researchers delays the project when AutoML can address the need.

An ML engineer needs to serve predictions with sub-10ms latency for a real-time bidding application that processes millions of requests per second.

Which serving architecture should they design?

A) Vertex AI Endpoints with optimized model serving and hardware acceleration (GPUs/TPUs), combined with request batching for throughput
B) Cloud Functions with cold starts for each prediction request
C) BigQuery ML PREDICT for real-time serving
D) A single Compute Engine CPU instance serving all traffic

 

Correct answers: A – Explanation:
Vertex AI Endpoints with hardware acceleration and batching achieve low latency at high throughput. Cloud Functions cold starts exceed latency requirements. BigQuery ML PREDICT is for batch, not real-time sub-10ms serving. A single CPU instance cannot handle millions of requests per second.
