QuestionQ203

Content Domain 3: Cloud Technology and Services

A company is building a new application on AWS. The company needs the application to remain available if an individual application component fails.

Which design principle should the company use to meet this requirement?

  • A Disposable resources
  • B Automation
  • C Rightsizing
  • D Loose coupling
Explanation

Loose coupling architecture makes components independent so that failure or changes in one component do not cascade to others, ensuring application availability despite individual failures. Disposable resources enable easy replacement but don't prevent failure impact, automation reduces manual work, and rightsizing optimizes resource costs.
