Topic 1 Question 347
A solutions architect has launched multiple Amazon EC2 instances in a placement group within a single Availability Zone. Because of additional load on the system, the solutions architect attempts to add new instances to the placement group. However, the solutions architect receives an insufficient capacity error.
What should the solutions architect do to troubleshoot this issue?
Use a spread placement group. Set a minimum of eight instances for each Availability Zone.
Stop and start all the instances in the placement group. Try the launch again.
Create a new placement group. Merge the new placement group with the original placement group.
Launch the additional instances as Dedicated Hosts in the placement groups.

Should be B
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html If you try to add more instances to the placement group later, or if you try to launch more than one instance type in the placement group, you increase your chances of getting an insufficient capacity error.
If you stop an instance in a placement group and then start it again, it still runs in the placement group. However, the start fails if there isn't enough capacity for the instance.
If you receive a capacity error when launching an instance in a placement group that already has running instances, stop and start all of the instances in the placement group, and try the launch again. Starting the instances may migrate them to hardware that has capacity for all of the requested instances.
