Selected Answer: D

Why isn't the answer Performance Efficiency? Even though the question mentions scaling, it didn't specifically state vertical or horizontal. Vertical is an example of Performance Efficiency and horizontal is an example of Reliability. Question said scaling is used to recover unhealthy applications, so horizontal scaling is implied. Horizontal scaling and Application Load Balancer fall under Reliability.

"This provides for automatic notification and tracking of failures, and for automated recovery processes that work around or repair the failure. With more sophisticated automation, it’s possible to anticipate and remediate failures before they occur." https://docs.aws.amazon.com/wellarchitected/latest/framework/rel-dp.html

Selected Answer: D

The reliability pillar focuses on ensuring that workloads are able to operate continuously and with minimal disruption. By using auto scaling and load balancing, the company can improve the reliability of their applications by automatically recovering from instances that become unhealthy. This helps maintain a consistent level of service and reduces the impact of failures.
