Exam AWS DevOps Engineer Professional topic 1 question 108 discussion

Exam question from Amazon's AWS DevOps Engineer Professional
Question #: 108
Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A DevOps engineer is troubleshooting deployments to a new application that runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. Instances sometimes come online before they are ready, which is leading to increased error rates among users. The current health check configuration gives instances a 60-second grace period and considers instances healthy after two 200 response codes from /index.php, a page that may respond intermittently during the deployment process. The development team wants instances to come online as soon as possible.

Which strategy would address this issue?

  • A. Increase the instance grace period from 60 seconds to 180 seconds, and the consecutive health check requirement from 2 to 3.
  • B. Increase the instance grace period from 60 seconds to 120 seconds, and change the response code requirement from 200 to 204.
  • C. Modify the deployment script to create a /health-check.php file when the deployment begins, then modify the health check path to point to that file.
  • D. Modify the deployment script to create a /health-check.php file when all tasks are complete, then modify the health check path to point to that file.

A and B are eliminated. First of all, it's not a good idea to extend grace period. The problem of this scenario is that the instance "come online" before some steps are finished properly. Between C and D, healthcheck shoud be implemented after all tasks are done and the instance is ready.

B wrong- 204 - No Content - Specifies the normal response code for the DELETE operation. A wrong - makes problem worse , delays startup and using index.php doesn't help C wrong- change to right health check but not at start of deployment D correct - change to right health check after the deployment script finishes
