DOP-C02 Question 130
Select 3You are working as a DevOps Engineer for a company that heavily utilizes AWS infrastructure. Your team is tasked with creating and managing resources across multiple environments (e.g., development, testing, production) while keeping the process automated and consistent. Which of the following methods would ensure infrastructure is created and managed in a software-defined manner, allowing for version control and repeatability?
- A
Use AWS CloudFormation to define infrastructure as code and deploy stacks to manage resources.
- B
Manually provision resources using the AWS Management Console for each environment to ensure control.
- C
Leverage AWS SDKs to programmatically provision and manage resources using custom scripts.
- D
Use AWS Elastic Beanstalk to automatically handle infrastructure provisioning for applications.
- E
Implement AWS OpsWorks to manage infrastructure as code using Chef or Puppet.
Show answer and explanation
Correct answers: A, C, E
Explanation
In a software-defined infrastructure approach, you use tools and services that allow you to define, manage, and automate resources as code. AWS CloudFormation, AWS SDKs, and AWS OpsWorks are all tools that support this paradigm by enabling repeatable, version-controlled, and automated resource management. Manual provisioning through the AWS Management Console and application-focused services like AWS Elastic Beanstalk do not align with the principles of software-defined infrastructure.
- A. Correct.
AWS CloudFormation is a service designed for infrastructure as code, allowing you to define resources in templates, version-control them, and deploy stacks consistently across environments. This is an ideal solution for software-defined infrastructure.
- B. Incorrect.
Manually provisioning resources using the AWS Management Console is error-prone, inconsistent, and not aligned with the principles of software-defined infrastructure or automation.
- C. Correct.
AWS SDKs enable programmatic resource management using code, which can be version-controlled and automated. This approach aligns with the software-defined infrastructure paradigm.
- D. Incorrect.
AWS Elastic Beanstalk is an application deployment service, not a tool specifically designed for managing infrastructure as code. While it simplifies application deployment, it does not provide granular control over all aspects of the infrastructure.
- E. Correct.
AWS OpsWorks is a configuration management service that supports infrastructure as code using Chef or Puppet, making it a viable option for managing software-defined infrastructure.
