As per earlier posts, the Enterprise Admin exam is currently Step 2 of the VCDX certification, and at some point it will form the second portion of the "Master VCP" certification.
I took the exam on April 17th, and have been waiting for my result, well yesterday I got it.... and I passed!
I received an email with my score report attached as a .pdf. There's no breakdown of any kind on the score report, just your score and the overall result.
The minimum score is 100, the maximum is 500, and the passing score is 300 - I scored 382 which I'm really happy with!
