Yesterday I've taken the Navision Installation and Configuration exam (a need for my company in order to maintain the Business Solutions competency). The result was a pass 
but I've to say that the exam was not what I was waiting for.
The exam was 60 questions, few questions with a single response and lots of questions (about 80% of the entire exam) with multiple responses (with no indication of how many correct answer you've to sign). Some of the questions (3 or 4) was totally confuse, I've really not understand what they want to ask me (I understand that this is a new exam, but some questions must be revisited).
However, if you plan to take the exam, remember to understand well how to create and install the database client and server, the application server, how to configure security and authorization, check the ODBC driver.
It's really important to print in your mind every screen of the installation process and the screen of the configuration windows: lots of question asks you where to find a certain option and you've to know the exact position inside the application (I'not a fan of these types of questions, instead of asking "where is the feature X" I think it's more important to ask "what is the feature X").
Despite all these surprise... it's done!
