One month ago I passed the Nutanix Certified Associate NCA exam. It is 50 multiple choice questions in 90 minutes and the official training like NHCF gives you basics but not enough for the real exam pattern. I was looking for realistic practice on Reddit and saw many people recommending
itexamstopics.com so I tried their web version for NCA Exam Questions. The online practice made it easy to revise regularly.
I studied by practicing exam-style questions rather than just theory. I focused on Recognize Nutanix Solutions and Tools, Describe Nutanix Platform Administration, Describe Cluster Configuration and Maintenance, and Demonstrate and Understand of Platform Health and Monitoring. I did multiple rounds of practice questions, real exam questions and sample questions which helped me understand how questions are asked from Prism UI and basic operations. If you are preparing for NCA, try their free demo - their Exam Questions are very close to the real 50 questions exam.
