AWS Certified Cloud Practitioner (CLF-C02) — Question 557

Which design principles are included in the reliability pillar of the AWS Well-Architected Framework? (Choose two.)

Answer options

• A. Automatically recover from failure.
• B. Grant everyone access to increase AWS service quotas.
• C. Stop guessing capacity.
• D. Design applications to run in a single Availability Zone.
• E. Plan to increase AWS service quotas first in a secondary AWS Region.

Correct answer: A, C

Explanation

The reliability pillar of the AWS Well-Architected Framework includes design principles like 'Automatically recover from failure' to automate responses to system failures, and 'Stop guessing capacity' to leverage cloud elasticity rather than over-provisioning. Restricting applications to a single Availability Zone decreases reliability, and the other options regarding service quotas are not standard framework principles.
