Which three commands should you run?

You have an Exchange Server organization that contains three servers that have Exchange Server
2013 installed and one server that has Exchange Server 2010 installed.
You create the custom RBAC roles shown in the following table.

The Seattle help desk manages all of the users in an organizational unit (OU) named Seattle. The
Miami help desk manages all of the users in an OU named Miami. The IT Administrators manage all
of the users in the forest.
You need to recommend which commands must be run to prevent only the members of both help
desks from modifying the properties of users who have a department attribute value of Manager.
