You need to deploy a fleet of identical web servers on Compute Engine that will automatically scale up when CPU utilization exceeds 70%.

What is the correct sequence of resources you must create to achieve this?

Create a Managed Instance Group (MIG) -> Create an Instance Template -> Configure Autoscaling.

Create a Custom Image -> Create an Instance Template -> Create a Managed Instance Group (MIG) with autoscaling.

Create an Unmanaged Instance Group -> Add VMs manually -> Enable Autoscaling.

Create an Instance Template -> Create a Target Pool -> Enable Autoscaling.
