Q441

You are configuring a model training pipeline with TensorFlow. What happens when you set the 'shuffle' option in the dataset?

  • A Data will be sorted
  • B Data will be mixed randomly
  • C Data will be duplicated
  • D Data will be compressed
Explanation Setting 'shuffle' randomizes the order of dataset elements, improving training outcomes, unlike the other options.
Q442

Which Google Cloud service enables managed Apache Kafka?

  • A Cloud Pub/Sub
  • B Google Cloud Dataflow
  • C Cloud Run
  • D Cloud Data Fusion
Explanation Cloud Pub/Sub is designed for messaging services, including Kafka functionalities, while others are not Kafka-specific.
Q443

A company needs to securely manage API keys. What should they use?

  • A Google Cloud Storage
  • B Secret Manager
  • C Cloud Scheduler
  • D Cloud Functions
Explanation Secret Manager is purpose-built for managing sensitive information securely, while the others do not offer this functionality.
Q444

You are configuring a machine learning model in Vertex AI. What happens when you set a higher 'batch size'?

  • A Slower training speeds
  • B Increased memory usage
  • C Lower model accuracy
  • D Reduced model complexity
Explanation Higher batch sizes increase memory consumption, while the other options either do not correspond to batch size changes or are incorrect.
Q445

Which service automates model tuning in AI Platform?

  • A Hyperparameter Tuning
  • B Machine Learning Engine
  • C Feature Store
  • D BigQuery ML
Explanation Hyperparameter Tuning automates the tuning process while the others do not directly handle tuning.
Q446

A company needs to process streaming data in real-time. Which Google Cloud service should they use?

  • A Cloud Pub/Sub
  • B Cloud SQL
  • C Cloud Storage
  • D Cloud Functions
Explanation Cloud Pub/Sub is designed for real-time stream processing, unlike the other options.
Q447

What happens when a GPU resource is allocated but underutilized on Google Cloud?

  • A Increased billing
  • B Reduced billing
  • C Automatic scaling down
  • D No impact on billing
Explanation Billing is based on allocated resources, regardless of utilization, making option A correct.
Q448

Which service is best for tuning ML models in production?

  • A AI Platform Hyperparameter Tuning
  • B BigQuery ML
  • C Cloud AutoML
  • D Dataflow
Explanation AI Platform Hyperparameter Tuning is specifically designed for optimizing model parameters, unlike other options which serve different functions.
Q449

A company needs to securely store their model datasets and backups. What should they use?

  • A Google Cloud Storage with encryption
  • B BigQuery for model datasets
  • C Cloud Pub/Sub
  • D Compute Engine instance
Explanation Google Cloud Storage with encryption provides secure storage for datasets, while other options are not designed for persistent data storage.
Q450

What happens when you choose 'Batch Prediction' in an AI Platform model?

  • A Real-time predictions are generated
  • B Rates are charged per individual prediction
  • C Predictions are processed in large batches
  • D Model training is initiated automatically
Explanation Batch Prediction processes predictions for multiple data points at once, while others misinterpret the function.
