Hurray! I've managed to complete the AX 2012 Retail certification yesterday. During registrations probably first thing you will notice is Microsoft will direct us to Pearson VUE instead of Prometric. I wanted to grab the second shot offer before it ends this month end so I quickly scheduled it for this week based on the online slots available.
The exam duration is 1.5 hours for 50 questions and the testing UI felt more like a windows app. Most of the questions are modeled based on how we apply the retail concepts and configuration setups rather than direct question and answers. If you have enough experience configuring the retail components this should not be an issue. Using the elimination rule for the options will come in handy to arrive at the correct answer. For the time being am just glad I didn't need to use the second shot offer!
