70-638 MS Office Communications Server 2007, Configuring

Recently, Microsoft released exam 70-638 (no official info page yet, but it’s all in Trika’s Blog).

As you might know, i’ve played with OCS 2007 in the past few days, and i’ve got a few leftover exam vouchers anyway. So yesterday, i decided to sign up for 70-638, and do the test this Saturday morning. This was possible because my favorite testing center (Digicomp in Zurich) is now offering Saturday testing.

I didn’t really expect to pass this exam, but i did (with more than 800 points). Okay, so what did happen at this exam?

First, the hard facts:

• 1.5 hours of time (didn’t even need half of that)
• 40 questions
• Only multiple choice questions, no PBT, no drag and drop, no nothing

What did i do to prepare myself for this exam? Not much, really. I’ve deployed OCS 2007 internally in the past few days, and crossread a few deployment guides.

First off, the exam was structured completely different than what i expected after taking the 70-236 Exchange 2007 MCTS. The exam varied widely from installing, to configuring and design. As such, it was a more classical approach, covering all topics of OCS 2007 use.

The questions were well written, and a few of them were more or less exact duplication of content from the available deployment guides, with even the same names and everything.

There also were several design questions, for which you need to understand the general architecture behind OCS 2007 - that isn’t as difficult as it might sound, because OCS 2007 is rather well structured, and the infrastructure design is easy to learn.

No talk about hardware requirements, some questions about upgrading from LCS 2005, etc.

This exam is easy - not as easy as 70-620, but also less difficult than the Exchange 2007 MCTS/MCITP exams.
