Where to Go from Here

One of the odd things about Exam 74-404 is that the Microsoft Learning Web site (http://www.microsoft.com/learning/en/us/exam.aspx?id=74-404#tab1) does not indicate that you actually earn a certification for passing this exam. Even so, the name of the exam (Microsoft Office Communications Server 2007 R2-UC Voice Specialization) implies that passing the exam results in receiving a certification.

Although this exam does not count as credit toward any additional certifications, those who pass Office Communications Server 2007 related exams often go on to take Exchange Server and Active Directory related exams.
