Server Scenario Interview Questions – Part 1

Server Scenario Interview Question : 1

Consider a Active Directory domain controller which was placed in a Head Office located at India, It was having a time zone of +GMT 5:30. If you are planning to add an additional domain controller in your branch office which was located at (eg) Japan with a +GMT 2.00 then

Possible doubts :

1) Do we need to create separate domain controller with separate domain at japan since the time zone changes.

2) Do we need to create a separate time server to synchronize both the domain controllers.

3) Do we need to use the +GMT 2.00 at japan, since no other options are available because of the changes in the time zone.

Answer :

Since the Active Directory uses the different time to synchronize between their servers you can use the same domain controller at India as your primary domain controller and you can add an additional domain controller from japan to the primary domain controller in India. It does not affect your time synchronization between your servers.
