Audience Profile

Experienced DBAs, Windows Server pros, team leads.

We designed this course based on our experience of having taught hundreds of classes to literally thousands of students. We tried very hard to make the labs, of which there are over 30, very oriented to a single concept such as Adding a Replica or Transferring Logons.
