Q321

A company needs to analyze large datasets in real-time. Which AWS service should they use?

  • A Amazon EMR
  • B Amazon Athena
  • C Amazon Kinesis
  • D AWS Glue
Explanation Amazon Kinesis is designed for real-time streaming; the others are more suited for batch processing or querying.
Q322

Which AWS service allows you to deploy machine learning models?

  • A Amazon SageMaker
  • B AWS Lambda
  • C Amazon RDS
  • D AWS CloudFormation
Explanation Amazon SageMaker is specifically designed for deploying machine learning models; the others serve different purposes.
Q323

A company needs to analyze large datasets in real-time. Which service should they use?

  • A Amazon S3
  • B Amazon Redshift
  • C Amazon Kinesis
  • D AWS Glue
Explanation Amazon Kinesis is designed for real-time data processing, while the other options do not specialize in this.
Q324

What happens when a Lambda function's timeout is reached?

  • A The function completes successfully
  • B An error is thrown and logs recorded
  • C It automatically retries the execution
  • D The function restarts from the beginning
Explanation When the timeout is reached, the function errors out and logs are generated; it does not automatically retry.
Q325

Which AWS service is best for real-time event streaming?

  • A Amazon Kinesis
  • B Amazon S3
  • C Amazon RDS
  • D Amazon EC2
Explanation Amazon Kinesis specializes in real-time data processing, unlike S3 (storage), RDS (databases), or EC2 (compute).
Q326

A company needs to securely manage access to resources. Which service should they use?

  • A AWS IAM
  • B AWS CloudTrail
  • C AWS Lambda
  • D AWS VPC
Explanation AWS IAM is designed specifically for managing access, while CloudTrail tracks API calls and Lambda runs code in response to events.
Q327

You are configuring AWS S3 bucket policies. What happens if you specify an action that is allowed for user A but denied for user B?

  • A User A can perform action.
  • B User B can perform action.
  • C Both users can perform action.
  • D Action denied for both users.
Explanation In AWS, permissions are evaluated based on the explicitly allowed actions, so user A can perform it while user B cannot.
Q328

Which AWS service allows real-time data processing?

  • A Amazon Kinesis
  • B Amazon S3
  • C AWS Lambda
  • D Amazon RDS
Explanation Amazon Kinesis enables real-time data streams, while S3 is for storage, Lambda is for serverless functions, and RDS is a managed database service.
Q329

A company needs to store large datasets safely and retrieve them quickly. Which AWS service should they use?

  • A Amazon S3
  • B Amazon Glacier
  • C AWS DynamoDB
  • D AWS Snowball
Explanation DynamoDB provides fast retrieval for large datasets, while S3 is for storage, Glacier is for archival, and Snowball is for data transfer.
Q330

You are configuring a machine learning model and want to avoid overfitting. What should you do?

  • A Increase training dataset size
  • B Reduce model complexity
  • C Add more features
  • D Both A and B
Explanation Increasing dataset size and reducing model complexity help prevent overfitting, while adding more features can worsen it.
