A company has data centers in Seattle and New York. A high-speed link connects the data centers.
Each data center runs a virtualization infrastructure that uses Hyper-V Server 2012 and Hyper-V Server 2012 R2.

Administrative users from the Seattle and New York offices are members of Active Directory Domain Services groups named SeattleAdmins and NewYorkAdmins,
respectively.
You deploy one System Center Virtual Machine Manager (SCVMM) in the Seattle data center.
You create two private clouds named SeattleCloud and NewYorkCloud in the Seattle and New York data centers, respectively.
You have the following requirements:
Administrators from each data center must be able to manage the virtual machines and services from their location by
using a web portal.
Administrators must not apply new resource quotas or change resource quotas.
You must manage public clouds by using the existing SCVMM server. You must use the minimum permissions required to
perform the administrative tasks.

Explanation:
User Roles in VMM:
Administrator – This role is exactly what you think, can manages the scope of everything within VMM.
Fabric Administrator – Can perform ALL administrative tasks, but only within a defined Scope. That scope can be a Host Group, a Private Cloud, or one or more
Library Servers.
Tenant Administrator – user role can define the scope of tasks performed by self-service users on their VMs, including creating and applying quotas on available
resources. So, this is the user role you should use if you want to give an administrator permission to manage self-service users and the resources they consume.
Members of the Tenant Administrator user role can also manage VM networks, including managing and deploying their own VMs within a defined scope. The scope
is limited to private cloud objects.

Application Administrator – user role can deploy and manage their own VMs within the scope and quotas defined by higher-level administrators. Note that this
user role is called the Self-Service User user role in VMM 2012 RTM.
