One of my friend recently taken EX294 exam , there is one question create and run ansible ad-hoc command. As per him he has correctly done that question as obejectives were completed but he get 0 in that question. Can any one suggest the proper way to complete that question.
Sounds like your friend breached the NDA by sharing exam content with you.

Not sure how saying you got 0 marks is a breach of NDA. Your quote doesn't mention anything about his score.
But in either case, there was a lot of chatter on reddit about others who had the same experience.
It comes down to this, if you, or friend, your dog or whoever thinks the score is wrong - they should challenge it - and have it remarked. But note that the score can go down as well as up!
