I passed the Nutanix Platform Professional exam yesterday after attending the online Nutanix Customer Administration Course.
I haven't read much about this online so if anybody is interested, I thought it was a pretty good course and test.  The instructor was very good.  The course is somewhat aimed at Nutanix partner who would be deploying Nutanix appliances.  As a customer/end-user, all the info was really good.  It was only a 2 day course so it wasn't the deep technical dive that I would have liked but it I also wasn't expecting that.
After the class I went to the Nutanix Education Portal where they have additional pre-recorded training.  I also saw that I could take the Nutanix Platform Professional exam and sure enough after reading the instructions I had access to it.  It was a 50 question test with 2 hours allotted.  I thought for the most part the questions were good and covered in the training or the training manual.
Nutanix has been going through a serious growth spurt and I hope their education and certifications grow with them.
Personally I very much enjoy working with Nutanix and Nutanix products so this was a lot of fun for me.

I guess I probably sound a bit like a Nutanix fan-boy, I just really appreciate how much easier it makes my life at work.
