AWS DevOps Engineer Professional DOP-C01 – Question521

You have an application running a specific process that is critical to the application's functionality, and have added the health check process to your Auto Scaling Group. The instances are showing healthy but the application itself is not working as it should. What could be the issue with the health check, since it is still showing the instances as healthy.

A. You do not have the time range in the health check properly configured
B. It is not possible for a health check to monitor a process that involves the application
C. The health check is not configured properly
D. The health check is not checking the application process

Correct Answer: D

Explanation:

Explanation:
If you have custom health checks, you can send the information from your health checks to Auto Scaling so that Auto Scaling can use this information. For example, if you determine that an instance is not functioning as expected, you can set the health status of the instance to Unhealthy. The next time that Auto Scaling performs a health check on the instance, it will determine that the instance is unhealthy and then launch a replacement instance.
