Amazon Web Services DOP-C02 Question Answer

A company runs a website by using an Amazon Elastic Container Service (Amazon ECS) service that is connected to an Application Load Balancer (ALB). The service was in a steady state with tasks responding to requests successfully. A DevOps engineer updated the task definition with a new container image and deployed the new task definition to the service. The DevOps engineer noticed that the service is frequently stopping and starting new tasks because the ALB health checks are failing. What should the DevOps engineer do to troubleshoot the failed deployment?

Ensure that a security group associated with the service allows traffic from the ALB.

Increase the ALB health check grace period for the service.

Increase the service minimum healthy percent setting.

Decrease the ALB health check interval.
