Q21

What happens when you assign an IAM role to an EC2 instance?

  • A Security groups change
  • B Instance gains permissions
  • C Virtual private cloud changes
  • D EBS volume size increases
Explanation The IAM role grants security permissions, others are unrelated to IAM roles.
Q22

Which AWS service is best for serverless applications?

  • A AWS Lambda
  • B Amazon EC2
  • C Amazon RDS
  • D AWS CloudFormation
Explanation AWS Lambda allows running code without provisioning servers, while EC2 and RDS require server management, and CloudFormation is for automation.
Q23

A company needs a highly resilient architecture. They must ensure data is available in another region. Which service should they use?

  • A Amazon S3 Cross-Region Replication
  • B EC2 Auto Scaling
  • C AWS CloudTrail
  • D Amazon CloudWatch
Explanation Amazon S3 Cross-Region Replication automatically replicates data to another region; Auto Scaling is for scaling capacity, not resilience.
Q24

You are configuring an IAM policy. Which of the following statements ensures access only to a specific bucket?

  • A Allow All Actions On *
  • B Allow GetObject on arn:aws:s3:::example-bucket
  • C Allow ListAllMyBuckets
  • D Deny Access to *
Explanation Allow GetObject on the specific bucket grants access; options A and C grant broader permissions, and D restricts access entirely.
Q25

Which Amazon service is best for data warehousing?

  • A Amazon Redshift
  • B Amazon RDS
  • C Amazon Aurora
  • D Amazon DynamoDB
Explanation Redshift is specifically designed for data warehousing; the others serve different purposes.
Q26

A company needs to store files that are accessed infrequently but need to be retained for compliance. Which storage class should they use?

  • A S3 Standard
  • B S3 Intelligent-Tiering
  • C S3 Glacier
  • D S3 One Zone-IA
Explanation S3 Glacier is ideal for archival storage; the others are not optimized for infrequent access.
Q27

What happens when you increase the instance type of an EC2 instance from t2.micro to t2.medium?

  • A Increased CPU and RAM resources
  • B Instance size remains unchanged
  • C Decreased cost for running
  • D Disk space is significantly larger
Explanation Upgrading to a larger instance type provides more CPU and RAM; the other options are inaccurate.
Q28

Which service provides a fully managed NoSQL database?

  • A Amazon DynamoDB
  • B Amazon RDS
  • C Amazon S3
  • D Amazon EC2
Explanation DynamoDB is the only fully managed NoSQL database service; RDS is for relational databases, S3 is object storage, and EC2 provides compute resources.
Q29

A company needs to securely store sensitive documents for compliance. What should they use?

  • A AWS Lambda
  • B Amazon S3 with SSE-256
  • C Amazon EC2
  • D AWS CloudFormation
Explanation Amazon S3 with server-side encryption (SSE) secures documents, while the other options do not provide secure storage solutions for sensitive documents.
Q30

What happens when an EC2 instance is stopped and restarted?

  • A IP address remains the same
  • B Data on EBS volumes is lost
  • C EBS volume is detached
  • D Instance data is preserved
Explanation When stopped, the IP changes unless it’s an Elastic IP; EBS data is preserved, not detached, and instance data is kept.
