Q411

You are configuring a Vertex AI model for automated predictions. What happens if you set the model's 'traffic split' parameter incorrectly?

  • A Model won't deploy
  • B Reduced prediction accuracy
  • C Increased prediction latency
  • D Predictions will not be served
Explanation Incorrect traffic split can cause unbalanced load, decreasing overall accuracy with varied input data.
Q412

Which Google Cloud service allows scalable ML model training?

  • A AI Platform
  • B Cloud Functions
  • C BigQuery ML
  • D Cloud Storage
Explanation AI Platform is specifically designed for scalable model training, while other options serve different purposes.
Q413

A company needs to process large data streams in real-time. Which service should they use?

  • A Cloud SQL
  • B Dataflow
  • C Cloud Run
  • D BigQuery
Explanation Dataflow is tailored for real-time stream processing, while other services are not designed for this task.
Q414

What happens when you set an IAM policy without a role assigned?

  • A Access is granted immediately
  • B Access is denied completely
  • C Policy is ignored
  • D Role defaults to 'viewer'
Explanation Without a role, IAM denies all access, as roles define permissions.
Q415

Which service is best for deploying ML models in GCP?

  • A AI Platform
  • B Cloud Storage
  • C BigQuery
  • D Cloud Functions
Explanation AI Platform is designed for ML model deployment; others serve different purposes.
Q416

A company needs to predict customer churn based on historical data. Which type of model is most appropriate?

  • A Time-series forecasting
  • B Classification model
  • C Clustering model
  • D Linear regression model
Explanation A classification model predicts categorical outcomes like churn; others do not match.
Q417

You are configuring a training job on AI Platform. What happens if your dataset is unbalanced?

  • A Model learns well from data
  • B Overfitting may occur
  • C Predictions will be more accurate
  • D Model's performance could degrade
Explanation Unbalanced datasets often lead to poorer model performance; other options are misleading.
Q418

Which Google Cloud service provides automatic scaling for workloads?

  • A Cloud Functions
  • B Compute Engine
  • C App Engine
  • D Cloud Storage
Explanation App Engine automatically scales applications based on traffic, while the others require manual scaling configurations.
Q419

A company needs to analyze real-time streaming data. Which service is best suited for this?

  • A BigQuery
  • B Dataflow
  • C Cloud Storage
  • D Cloud Functions
Explanation Dataflow is designed for real-time streaming data processing, while BigQuery is optimized for batch analysis.
Q420

You are configuring IAM roles for a project. What will happen if a user has both an Admin and a Viewer role on a resource?

  • A Admin role overrides Viewer role
  • B User gets no access
  • C Only Admin role applies
  • D Access will be denied
Explanation IAM roles are cumulative, so the Admin role grants all permissions, including those of the Viewer role.
