Q291

What happens when you enable BigQuery's streaming inserts?

  • A Immediate data consistency
  • B Data is available immediately
  • C Performance issues
  • D Biased query results
Explanation Streaming inserts allow immediate querying of incoming data, unlike batch loads.
Q292

Which Google Cloud service is optimal for handling large-scale data processing?

  • A BigQuery
  • B Compute Engine
  • C Cloud Storage
  • D App Engine
Explanation BigQuery is designed for scalable data analysis while the others serve different purposes.
Q293

A company needs to predict customer churn using historical data. Which tool is best suited for this task?

  • A AutoML Tables
  • B Cloud Dataproc
  • C Pub/Sub
  • D Dataflow
Explanation AutoML Tables provides machine learning capabilities tailored for structured data prediction tasks.
Q294

What happens when you overflood a bucket in Google Cloud Storage with write requests?

  • A Bottlenecking and latency increase
  • B Insufficient permissions error
  • C Requests are processed instantly
  • D Bucket gets deleted automatically
Explanation Overloading requests can lead to increased latency and bottlenecking, impacting performance, unlike the other options.
Q295

Which service is best for automating machine learning model deployment?

  • A Google Cloud AI Platform
  • B Google Cloud Storage
  • C Google BigQuery
  • D Google Cloud Functions
Explanation AI Platform automates model deployment; Storage and BigQuery are for storage and analytics, while Functions execute code in response to events.
Q296

A company needs to manage user access across multiple Google Cloud projects. Which service should they use?

  • A IAM
  • B Cloud Identity
  • C Resource Manager
  • D Cloud Run
Explanation IAM allows management of user permissions across projects; Cloud Identity is for user identity management, and Resource Manager manages project resources.
Q297

What happens when you set a higher learning rate in gradient descent?

  • A Faster convergence to local minimum
  • B No change in training
  • C Possibility of overshooting minima
  • D Slower convergence rates overall
Explanation A higher learning rate can cause overshooting the minimum; options A and D are incorrect because they imply stability, and B underestimates the effect.
Q298

Which Google Cloud service can automatically scale machine learning models?

  • A AI Platform
  • B BigQuery
  • C Cloud Functions
  • D Dataflow
Explanation AI Platform provides built-in scaling for ML models; others do not focus on ML scaling.
Q299

A company needs to pick the appropriate AI model for predicting customer churn based on historical data points. What should be prioritized in model selection?

  • A Model interpretability
  • B Training time
  • C Data volume used
  • D Input feature variety
Explanation Model interpretability is critical for business understanding; the other options are important but secondary in this context.
Q300

You are configuring a Cloud Pub/Sub topic for event-driven architecture. What happens if you set a retention duration of 24 hours?

  • A Messages expire after 24 hours
  • B Messages are kept indefinitely
  • C Messages delayed for 24 hours
  • D Only subscribers see messages
Explanation Messages will expire after the specified retention duration; others do not reflect the behavior correctly.
