You have a group of developers who launch multiple VM.

You have a group of developers who launch multiple VM.Standard3.Flex compute in-stances every day into the compartment Dev. As a result, your Oracle Cloud Infrastructure (OCI) tenancy quickly hits the service limit for this shape, and other groups can no longer create new instances using the VM.Standard3.Flex shape. Therefore, your company issues a new mandate that the Dev compartment must include a quota that allows the use of only 20 VM.Standard3.Flex OCPUs per availability domain, without affecting any other compartment in the tenancy. Which quota statement would you use to implement this new requirement?
