Well as the title says I just got back from 71-236 Config Exchange 2007.
The exam consisted of 76 questions with 180 mins to complete.
I found it quite tuff as it consisted of mainly Exchange Management Shell questions which I haven't used much. Also as expected there were a few questions on roles, routing topologies, clustering and also B & R. All multiple choice bar two which were drag from the left pane to the right pane in the correct order type questions

My advice to anyone taking this exam is know your cmdlets inside out and also the Exchange 2007 roles!!
My prep consisted of three VM's each with different roles, Technet Virtual labs and some articles on msexchange.org
Now back to 70-285 to complete my mcse:messaging.
