Nitpicking 101: AD snapshot- correct way..

Hey,

In order to "snapshot" AD I go to cmd and use ntdsutil. When I read how to do it I see "2 schools" .

ntdsutil

activate instance ntds

snapshot 

create

Both on Technet! Is there any difference between the two? Which one is a correct way. Most of the commands go only one way- thus me asking this question.

Thanks!
