Which design principles are included in the reliability pillar of the AWS Well-Architected Framework?

The reliability pillar of the AWS Well-Architected Framework emphasizes building systems that can recover from failures and dynamically adjust to meet demand. This includes designing to automatically recover from failures and implementing mechanisms to manage capacity demands, avoiding manual guesswork. The other options do not align with core reliability principles, as operating in a single Availability Zone or preemptively adjusting quotas in a secondary region does not inherently improve reliability.
