You want to create a policy to allow the NetworkAdmins group to manage Virtual Cloud Network (VCN) in compartment C. You want to attach this policy to the tenancy. The compartment hierarchy is shown below.
Which policy statement can be used to accomplish this task?
To apply a policy at the tenancy level, you must specify the full path from the root compartment down to the target compartment. Therefore, to allow the NetworkAdmins group to manage the Virtual Cloud Network (VCN) in compartment C, the policy statement should be: 'Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C'. This indicates the specific compartment hierarchy necessary when attaching the policy to the tenancy.
