Correct Answers: A and G 
The Business unit security model is the basis for Dataverse security. The model controls access to the data using security roles, teams, and users. By linking all of them together, you are getting a role-based security model. By default, the Organization is a top-level of a business unit hierarchy. Each business unit has a default team. You cannot change or delete the default team. You must assign every user to only one business unit. 
The business unit security model uses security roles to assign them to the users or teams. A team also can consist of users from different business units. 
The most effective way to manage security is to provide access to the teams instead of individual users. In this case, you do not need to change any user`s settings. You just add the new user to the team. To provide access to the data in another business unit, you need to create a new team in that business unit, like the Marketing team in a Marketing business unit. Then you can add sales managers to this team. If needed, you can create a specific security role to access the data in this business unit and assign this role to the new team. 
All other options are incorrect.
