Q131

A company needs to securely store sensitive customer data and allow access based on user roles. Which service should they use?

  • A Amazon DynamoDB
  • B Amazon S3 with IAM
  • C Amazon RDS with Aurora
  • D AWS Glue
Explanation Amazon S3 can manage access control via IAM roles, making it suitable for securing sensitive data.
Q132

What happens when you increase the learning rate in a training job?

  • A Slower convergence
  • B Faster convergence
  • C No effect on training
  • D Higher accuracy
Explanation Increasing the learning rate typically accelerates model training but risks overshooting minima, possibly leading to instability.
Q133

Which service optimally helps in real-time data processing?

  • A Amazon Kinesis
  • B Amazon S3
  • C Amazon RDS
  • D AWS Lambda
Explanation Amazon Kinesis is specifically designed for real-time data streaming, unlike the others which serve different functions.
Q134

A company needs to predict customer churn using available user data. Which ML model is most appropriate?

  • A Linear Regression
  • B Support Vector Machines
  • C Decision Trees
  • D Time Series Forecasting
Explanation Decision Trees effectively model classification tasks like predicting churn, unlike the other options which are not ideal for this specific problem.
Q135

You are configuring a model deployment on AWS SageMaker. What happens when you set the endpoint to "Asynchronous"?

  • A Immediate inference responses
  • B Batch processing of data
  • C Long-running tasks are handled
  • D Low-cost deployment options
Explanation Asynchronous endpoints handle long-running inference requests, while other options do not reflect the nature of asynchronous processing.
Q136

Which service is best for real-time data streaming?

  • A Amazon Kinesis
  • B AWS Glue
  • C Amazon S3
  • D Amazon Athena
Explanation Amazon Kinesis specializes in real-time data processing, unlike the others which serve different purposes.
Q137

A company needs to deploy machine learning models at scale while maintaining cost efficiency. What is the best approach?

  • A Use AWS Lambda for serverless execution
  • B Deploy on EC2 with auto-scaling features
  • C Use SageMaker for automated deployment
  • D Implement Fargate for container orchestration
Explanation AWS SageMaker provides built-in scaling and cost efficiency for ML deployments, while the others do not specifically target ML at scale.
Q138

You are configuring an IAM policy for a group in your organization. What happens if the policy has both Allow and Deny statements?

  • A Allow takes precedence over Deny
  • B Deny takes precedence over Allow
  • C They conflict and cancel each other out
  • D The user has no permissions
Explanation In IAM policies, Deny statements always override Allow statements, ensuring security.
Q139

Which AWS service provides a managed environment for running machine learning models?

  • A Amazon SageMaker
  • B AWS Lambda
  • C Amazon RDS
  • D AWS Glue
Explanation Amazon SageMaker is designed specifically for machine learning, while the others serve different purposes.
Q140

A company needs to optimize its model training cost. Which technique should they consider?

  • A Use spot instances
  • B Increase instance size
  • C Use on-demand instances
  • D Choose multi-AZ deployment
Explanation Using spot instances can significantly reduce costs compared to on-demand pricing.
