Q21

What happens when you define an IAM policy with a Deny effect without any Allow statements?

  • A No permissions granted
  • B Full access granted
  • C Limited access granted
  • D Resource access is monitored only
Explanation A Deny statement overrides any permissions, resulting in no access granted; others incorrectly suggest some form of access.
Q22

Which service allows you to create and manage serverless applications?

  • A AWS Lambda
  • B Amazon EC2
  • C AWS Direct Connect
  • D Amazon RDS
Explanation AWS Lambda is designed for serverless applications, while the others are not.
Q23

A company needs to analyze large datasets stored in S3 with minimal latency. What should they consider?

  • A AWS Data Pipeline
  • B AWS Glue
  • C Amazon Redshift
  • D AWS CloudFormation
Explanation Amazon Redshift is optimized for fast query performance on large datasets.
Q24

You are configuring an IAM role with S3 read permissions. What happens if you attach an explicit deny policy?

  • A Deny overrides allow permissions
  • B Read access is allowed
  • C Role permissions remain unchanged
  • D IAM role is deleted
Explanation Explicit deny policies take precedence over allow policies in IAM.
Q25

Which service can be used for ETL processes in AWS?

  • A AWS Glue
  • B Amazon S3
  • C Amazon RDS
  • D Amazon SNS
Explanation AWS Glue is specifically designed for ETL tasks, while the others serve different purposes.
Q26

A company needs to ensure that its S3 buckets are only accessible from a specific VPC. What should the company configure?

  • A VPC Endpoint policy
  • B IAM user policy
  • C CloudFront distribution
  • D CORS configuration
Explanation A VPC Endpoint policy restricts S3 access to the specified VPC, ensuring security.
Q27

You are configuring Amazon Redshift. What happens when you choose concurrency scaling?

  • A Increases costs immediately
  • B Scales storage automatically
  • C Adds temporary clusters as needed
  • D Limits query execution time
Explanation Concurrency scaling adds temporary clusters to handle spikes in query load, improving performance.
Q28

Which service allows for serverless data warehousing?

  • A Amazon Redshift
  • B Amazon Athena
  • C Amazon EMR
  • D Amazon RDS
Explanation Amazon Athena enables serverless queries on data in S3; Redshift is not serverless, EMR is for big data, and RDS is for relational databases.
Q29

You are configuring an IAM policy with the action 's3:PutObject'. What should you ensure regarding the resource?

  • A It must be an IAM role
  • B It should specify an S3 bucket
  • C It requires a Lambda function
  • D It can be any AWS resource
Explanation The resource must be an S3 bucket for 's3:PutObject' action; IAM roles and Lambda functions are not applicable here, and any AWS resource does not apply.
Q30

A company is using Amazon S3 for storage. What happens when they delete an object with versioning enabled?

  • A The object is permanently deleted.
  • B A delete marker is created.
  • C The version is archived.
  • D All versions are automatically deleted.
Explanation With versioning enabled, a delete marker is created to signify that the object has been deleted while the actual data remains accessible; thus permanent deletion and auto-archiving are incorrect.
