Correct Answer: D
The managed instance group (MIG) gives you high availability: If an instance stops, crashes, is malfunctioning or is deleted by an action other than an instance group management command, the MIG automatically recreates that instance in accordance with the original instance’s specification.
Managed instance groups support autoscaling that dynamically adds or removes instances. You have to setup a Load Balancer in front of the MIG
