Question 12:
An architect is finalizing the design for a new vSphere platform based on the following information:
All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.
All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes.
All management virtual machines will be hosted on a dedicated cluster.
