DCA Exam Re-take

I did not pass the DCA exam on my first go, can I re-take the exam for free or do I have to pay again at Examity?

I doubt retaking an exam is free (I have NEVER experienced that retaking to an exam would be free anywhere). Though, get in touch with Mirantis Training department and ask them: Docker Certified Associate (DCA) Exam - Mirantis Training
