AWS Certified Cloud Practitioner — Question 323

A company that operates in the AWS Cloud wants to test workloads and team responses to simulated events. The company will conduct an exercise to identify potential issues that need to be addressed.

Which design principle of the AWS Well-Architected Framework does this exercise represent?

Answer options

• A. Anticipate failure.
• B. Automatically recover from failure.
• C. Measure overall cost efficiency.
• D. Implement loosely coupled dependencies.

Correct answer: A

Explanation

Conducting simulations to test workloads and team responses directly aligns with the 'Anticipate failure' design principle of the Reliability pillar. This practice, often referred to as game days, helps organizations identify potential failure modes and validate recovery procedures before real incidents occur. The other options represent different design principles focused on self-healing, cost tracking, and architectural decoupling rather than active testing and simulation.
