Q281

A company needs to classify images of cats and dogs. Which algorithm is recommended?

  • A K-Means Clustering
  • B Logistic Regression
  • C Convolutional Neural Network
  • D Decision Tree
Explanation Convolutional Neural Networks are specifically designed for image classification tasks, while the other algorithms are less effective for this purpose.
Q282

What happens when you apply regularization in a linear regression model?

  • A Increases model complexity
  • B Improves model interpretability
  • C Reduces overfitting
  • D Eliminates all errors
Explanation Regularization reduces overfitting by penalizing large coefficients, while the other options are incorrect regarding its effects.
Q283

A company needs to integrate machine learning with their data streams. Which AWS service should they primarily use?

  • A Amazon Kinesis
  • B AWS Lambda
  • C Amazon SNS
  • D Amazon S3
Explanation Amazon Kinesis is designed for real-time data processing, suitable for ML integrations, while AWS Lambda is for event-driven compute, SNS is for messaging, and S3 is for storage.
Q284

You are configuring an Amazon SageMaker training job. How can you optimize the training cost?

  • A Use a larger instance size
  • B Use multi-model endpoints
  • C Use spot instances
  • D Increase training duration
Explanation Using spot instances reduces training costs significantly as they leverage unused EC2 capacity, unlike the other options which either increase costs or do not ensure savings.
Q285

What happens when an Amazon S3 bucket policy denies access to all roles except one?

  • A Only thespecified role has access
  • B All IAM users gain access
  • C Public access is granted
  • D Access is denied for everyone
Explanation The bucket policy restricts access so only the specified role can access the bucket, making the other options incorrect regarding access permissions.
Q286

Which service is best for real-time data streaming in AWS?

  • A Amazon Kinesis
  • B Amazon S3
  • C AWS Lambda
  • D Amazon RDS
Explanation Amazon Kinesis is specifically designed for real-time data streaming, while the others serve different purposes.
Q287

A company needs to prepare a large dataset for training machine learning models. Which AWS service can best help automate this process?

  • A Amazon SageMaker
  • B Amazon EC2
  • C AWS Batch
  • D AWS Glue
Explanation AWS Glue is designed for data preparation and ETL, while SageMaker focuses on model building.
Q288

What happens when a machine learning model deployed on AWS Lambda exceeds the maximum execution timeout?

  • A Model automatically retries
  • B Execution is terminated
  • C Results are saved partially
  • D Lambda scales up automatically
Explanation Exceeding the timeout results in termination of execution, unlike the other options that suggest alternative behaviors.
Q289

Which AWS service simplifies the machine learning workflow through automated model tuning?

  • A Amazon SageMaker
  • B Amazon EC2
  • C AWS Lambda
  • D Amazon RDS
Explanation Amazon SageMaker provides tools for automated model tuning, while EC2 and RDS are compute/storage services and Lambda handles serverless functions.
Q290

What happens when you deploy a model using AWS Lambda for real-time inference?

  • A It scales automatically based on requests.
  • B It requires manual scaling.
  • C It cannot handle multiple requests.
  • D It only supports batch processing.
Explanation AWS Lambda automatically scales to handle multiple concurrent invocations, unlike options B, C, and D which are incorrect scenarios.
