Question

A company is migrating a legacy application to AWS. The application runs on EC2 instances across multiple Availability Zones behind an Application Load Balancer (ALB).

After deployment, users report random application errors that were not present before migration, even though target health checks are passing. Which solution will meet this requirement?

Options

  • ASet the routing algorithm of the target group to least outstanding requests.
  • BTurn on anomaly mitigation for the target group.
  • CTurn off the cross-zone load balancing attribute of the target group.
  • DIncrease the deregistration delay attribute of the target group.
