Q221

You are configuring an IAM policy that should allow access to specific S3 buckets. What will happen if you configure a policy but do not assign it to any IAM users or roles?

  • A Policy applies to all users
  • B Users will have access
  • C Policy has no effect
  • D Errors will occur on access
Explanation Without assignment, the policy has no effect.
Q222

A company needs to gather real-time metrics about their application performance. Which service should they use?

  • A AWS CloudTrail
  • B Amazon CloudWatch
  • C AWS Config
  • D AWS X-Ray
Explanation Amazon CloudWatch provides real-time metrics, whereas others serve different monitoring purposes.
Q223

Which AWS service provides seamless scaling for applications?

  • A Amazon ECS
  • B AWS Auto Scaling
  • C Amazon RDS
  • D AWS Lambda
Explanation AWS Auto Scaling automatically adjusts the capacity based on demand; ECS, RDS, and Lambda can scale, but not seamlessly for all application types.
Q224

A company needs to ensure that only valid users have access to its application through Single Sign-On (SSO). Which AWS service should it implement?

  • A Amazon Cognito
  • B AWS IAM
  • C AWS Organizations
  • D Amazon API Gateway
Explanation Amazon Cognito supports SSO functionality; IAM and Organizations do not provide native SSO capabilities, and API Gateway manages APIs but not user access directly.
Q225

You are configuring an AWS CloudFormation stack. What happens if a resource in your stack has a deletion policy of 'Retain'?

  • A It gets deleted when the stack is deleted.
  • B CloudFormation preserves the resource on stack deletion.
  • C The resource is recreated on next update.
  • D No impact; the resource is ignored.
Explanation A 'Retain' deletion policy means the resource remains after stack deletion; the other options inaccurately describe the behavior of deletion policies.
Q226

Which AWS service automatically scales your application based on demand?

  • A AWS Auto Scaling
  • B AWS Lambda
  • C Amazon S3
  • D Amazon RDS
Explanation AWS Auto Scaling dynamically adjusts capacity, while others do not scale automatically.

A company needs to improve database performance for read-heavy workloads. Which solution should they consider?

  • A Read Replicas in RDS
  • B DynamoDB Streams
  • C Amazon Redshift
  • D EFS with caching
Explanation Read Replicas in RDS optimize performance for read-heavy applications, unlike the other options which serve different purposes.
Q228

You are configuring a CloudFormation template. What happens if a resource's logical ID is changed?

  • A Resource is deleted and recreated
  • B Template fails during deployment
  • C None, logical ID remains same
  • D AWS ignores the change
Explanation Changing a logical ID means CloudFormation treats it as a new resource, leading to deletion of the old one.
Q229

Which AWS service provides a fully managed NoSQL database?

  • A Amazon DynamoDB
  • B Amazon RDS
  • C AWS Lambda
  • D Amazon Aurora
Explanation DynamoDB is designed specifically for NoSQL workloads, while RDS and Aurora are relational database services, and Lambda is a serverless computing service.

  • A Amazon Kinesis
  • B Amazon EC2
  • C AWS Glue
  • D Amazon S3
Explanation Amazon Kinesis is specifically built for real-time data processing, whereas EC2 is for compute, Glue for ETL tasks, and S3 is for storage.
