AWS Certified Cloud Practitioner — Question 758

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

Explanation

Automatically recovering from failure is a foundational design principle of the Reliability pillar, ensuring that systems monitor KPIs and automate healing processes when thresholds are breached. Stopping guessing capacity is also a reliability principle to prevent under-provisioning, whereas running in a single Availability Zone or granting unrestricted quota access violates AWS reliability and security best practices.
