Which of the following could explain why the administrator is unable to save the completed profile?

The administrator does not have the proper vSphere edition so this feature is not licensed

B.
The Host Profiles service is stopped and must be restarted to access this option

No DRS/HA Cluster has been defined, and Host Profiles must be applied to a cluster.
