Q421

A company wants to analyze large datasets quickly. Which Google Cloud service should they use?

  • A BigQuery
  • B Cloud Functions
  • C Cloud Storage
  • D Cloud Pub/Sub
Explanation BigQuery is designed for analyzing large datasets efficiently; the others serve different purposes.
Q422

What happens when you enable versioning in a Cloud Storage bucket?

  • A Only latest versions are kept.
  • B Previous versions are permanently deleted.
  • C All versions are retained.
  • D Versioning cannot be enabled later.
Explanation Enabling versioning retains all object versions; other options misrepresent its behavior.
Q423

You are configuring a TensorFlow model on AI Platform. Which hyperparameter tuning method is NOT available?

  • A Grid search
  • B Random search
  • C Bayesian optimization
  • D Forecasting analysis
Explanation Forecasting analysis is unrelated to hyperparameter tuning; the others are valid methods.
Q424

Which service is best for deploying machine learning models at scale?

  • A AI Platform Prediction
  • B Cloud Functions
  • C Cloud Storage
  • D Compute Engine
Explanation AI Platform Prediction is designed for model deployment, while others serve different purposes.
Q425

A company needs to predict customer churn using sequential data. Which model would be most appropriate?

  • A Logistic Regression
  • B LSTM
  • C k-Nearest Neighbors
  • D Decision Trees
Explanation LSTM is ideal for handling sequential data, unlike the other options.
Q426

What happens when you set a Cloud Pub/Sub topic to a retention period of 7 days?

  • A Messages are deleted after 7 days
  • B Messages are kept indefinitely
  • C Only new messages are retained
  • D Messages are stored for 1 month
Explanation Messages in Pub/Sub will be deleted after the retention period expires, which is set to 7 days in this case.
Q427

Which service provides managed machine learning endpoints?

  • A Vertex AI
  • B Cloud Functions
  • C Cloud Run
  • D BigQuery
Explanation Vertex AI provides managed ML endpoints, while the others focus on services like running applications or data analysis.
Q428

A company needs to analyze streaming data in real-time. Which approach should they adopt?

  • A Batch processing with Cloud Dataflow
  • B Event-driven approach with Pub/Sub
  • C Static data stored in Cloud Storage
  • D Scheduled queries in BigQuery
Explanation An event-driven approach with Pub/Sub enables real-time processing, whereas the other options involve delayed analysis.
Q429

You are configuring a model to predict housing prices based on various features. What happens when you use too many input features?

  • A Underfitting the model
  • B Overfitting the model
  • C Improved model accuracy
  • D Reduced computation time
Explanation Using too many features can lead to overfitting, while the other options either distort model training or inaccurately represent outcomes.
Q430

Which service is optimal for real-time data processing in GCP?

  • A Cloud Dataflow
  • B Cloud Functions
  • C Cloud Storage
  • D BigQuery
Explanation Cloud Dataflow is specifically designed for stream and batch data processing, while other options serve different purposes.
