Q371

A company needs to automate AWS resource provisioning with a single command. Which service should they use?

  • A AWS CloudFormation
  • B AWS CodeDeploy
  • C AWS OpsWorks
  • D Amazon Inspector
Explanation AWS CloudFormation allows defining infrastructure as code for single-command provisioning, while others do not serve the same purpose.
Q372

You are configuring an Auto Scaling group. What happens when the desired capacity is set to 0?

  • A All instances are terminated
  • B Instances are stopped
  • C Instances are placed in standby
  • D No change occurs at all
Explanation Setting desired capacity to 0 terminates all instances in the Auto Scaling group, while others do not physically remove them from the group.
Q373

Which AWS service allows you to decouple application components?

  • A Amazon SQS
  • B AWS CodeDeploy
  • C AWS Lambda
  • D AWS CloudFormation
Explanation Amazon SQS is a message queue service that enables decoupling, while others serve different purposes.
Q374

A company needs to automate code testing and deployment using CI/CD. Which AWS service should they primarily use?

  • A AWS CodePipeline
  • B Amazon EventBridge
  • C AWS Systems Manager
  • D Amazon RDS
Explanation AWS CodePipeline automates CI/CD workflows, while others do not focus specifically on CI/CD.
Q375

What happens when an AWS Auto Scaling group reaches its maximum capacity limit?

  • A No new instances launched
  • B Instances get terminated
  • C Load balancer fails
  • D Traffic gets routed incorrectly
Explanation When the limit is reached, no new instances are launched; others describe incorrect behaviors.
Q376

Which service allows you to run code without provisioning servers?

  • A AWS Lambda
  • B Amazon EC2
  • C AWS Elastic Beanstalk
  • D AWS Fargate

A company needs to ensure their Elastic Beanstalk application can automatically scale based on load. What should they configure?

  • A Application Load Balancer
  • B Auto Scaling policies
  • C CloudFront distribution
  • D RDS Performance Insights
Explanation Only Auto Scaling policies allow automated scaling based on current load, while the others do not directly manage instance scaling.
Q378

What happens when you increase the IOPS of an Amazon EBS volume?

  • A Latency decreases immediately
  • B Cost increases slightly
  • C Performance improves for all apps
  • D Nothing changes until reboot
Explanation Increasing IOPS directly raises costs for EBS, but it doesn't guarantee performance improvements for all applications nor immediate latency reduction.
Q379

Which AWS service can automate backups for Amazon RDS?

  • A AWS Backup
  • B Amazon S3
  • C AWS Lambda
  • D Amazon CloudFront
Explanation AWS Backup specializes in backup orchestration, including RDS, while the others serve different primary functions.
Q380

A company needs to allow its developers to deploy applications through a CI/CD pipeline. Which architecture pattern should be used?

  • A Monolithic architecture
  • B Serverless architecture
  • C Microservices architecture
  • D Event-driven architecture
Explanation Microservices architecture enables independent deployments, crucial for CI/CD; the other patterns are less suited for such flexibility.
