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

  • A Amazon RDS
  • B AWS Glue
  • C Amazon Kinesis
  • D Amazon SQS
Explanation Amazon Kinesis is optimized for real-time data processing, unlike the other services.
Q183

You are configuring an IAM role for accessing S3. What should you ensure?

  • A Policy attached to user only
  • B Role has EC2 instance permissions
  • C Policy allows specific actions on S3
  • D Role must be in same region
Explanation The policy must grant the necessary S3 permissions for access, while others are irrelevant or incorrect.
Q184

Which AWS service allows you to run code without provisioning servers?

  • A AWS Lambda
  • B EC2
  • C ECS
  • D AWS CodePipeline
Explanation AWS Lambda is specifically designed for serverless computing, while the others require server management.
Q185

A company needs to store large amounts of unstructured data. Which service should they use?

  • A Amazon RDS
  • B AWS S3
  • C AWS DynamoDB
  • D Amazon Redshift
Explanation AWS S3 is optimized for large unstructured data storage, whereas the others are more suitable for structured data.
Q186

What happens when an EC2 instance is terminated?

  • A Data on EBS is lost
  • B Public IP is retained
  • C Instance state is paused
  • D Billing stops immediately
Explanation Data on EBS volumes is only retained if they are marked as 'persistent'; the public IP is released, instance is not paused, and billing does not immediately stop.
Q187

Which service allows you to run code without provisioning servers?

  • A AWS Lambda
  • B EC2 Instances
  • C S3 Storage
  • D Elastic Beanstalk
Explanation AWS Lambda executes code without server management; EC2 requires server provisioning, S3 is for storage, and Elastic Beanstalk is for web app deployment.
Q188

A company needs to ensure that its S3 bucket content is not publicly accessible. What should they do?

  • A Enable bucket policy restrict public access
  • B Set ACL to public-read
  • C Remove all objects and re-upload
  • D Enable versioning on the bucket
Explanation Setting a bucket policy to restrict public access ensures no unauthorized access; public-read ACL contradicts this, while the other options are irrelevant.
Q189

You are configuring IAM roles for an Amazon ECS task. What happens if the task tries to access an S3 bucket without permissions?

  • A Access granted automatically
  • B Access denied for the task
  • C IAM roles are applied retroactively
  • D Task will have limited access
Explanation Without proper permissions, access is denied; automatic access granting does not occur, roles cannot apply retroactively, and limited access isn't an option.
Q190

Which service would you use for building event-driven applications?

  • A Amazon SNS
  • B AWS Elastic Beanstalk
  • C Amazon CloudWatch
  • D Amazon RDS
Explanation Amazon SNS is designed for event-driven applications; the others do not fit this purpose.
