An object has inherited permissions from two parent objects.
What is true about the permissions on the object?

A.
The common permissions between the two are applied and the rest are discarded.

B.
The permissions are combined from both parent objects.

C.
No permissions are applied from the parent objects.

D.
The permission is randomly selected from either of the two parent objects.

Explanation:

Most inventory objects inherit permissions from a single parent object in the hierarchy. For example, a datastore inherits permissions from either its parent datastore folder or parent datacenter. Virtual machines inherit permissions from both the parent virtual machine folder and the parent host, cluster, or resource pool simultaneously. To restrict a user’s privileges on a virtual machine, you must set permissions on both the parent folder and the parent host, cluster, or resource pool for that virtual machine.
