Scenario: You are part of an IT group managing Active Directory for a mid-size organization. A contracted research group with their own IT team operating from a remote location with a slow network connection has requested that they be able to setup a Child Domain in your organization's domain. The remote IT teams argument is based on their slow network, and their need to access and administer the local server that would need to exist in their remote location. Your team is split between allowing the Child Domain or recommending an Organizational Unit and delegating the remote IT team access. Yours is the deciding vote -- and cost is being considered a deciding factor. What option do you support as the best option in this scenario? What DC configuration for the remotely located server would be the best option?
If instead of cost, the deciding factor was the slow speed of their network, what option would you support as the best option?

the answer to the first question is organizational unit. this is because in this scenario that we have before us, cost is a deciding factor. a unit as this can adapt to changes, it is flexible and also not very complex

2.

answer to question 2 is PDC emulator. this emulator can perform the function synchronization of time across every domain controller that is in the domain. other of its functions are, authentication and changing of passwords.

3.

the answer to the 3rd question is child domain. It is a factor in this scenario because it works well in a situation where there is an issue of slow network connection.
