Which solution accomplishes this with the LEAST amount of effort?

    Use a simple scaling policy based on a custom metric that measures the average active requests of all
    EC2 instances

  • B

    Use a simple scaling policy based on the Auto Scaling group GroupDesiredCapacity metric

    Use a target tracking scaling policy based on the ALB's ActiveConnectionCount metric

  • D

    Use a target tracking scaling policy based on the ALB's RequestCountPerTarget metric
