    Overview
     Red hat certification are such different type of certification which are   known for there uniqueness in the market of open source linux.It have lot of reason behind that one is it not just a multiple choice exam paper as other exam in IT certification rather than performance based analysis of your skills.

Preparation/Training
Red hat gives a official training which enrolls you in practical understanding and dept learning because it's just not a reading a book and practicing mock exam due to a lot difference in formats of exam. 

Exam Format 
                                                          It is half day training session and a 2.30 hours practical in which you have to perform on machine as given problems in your certification exam. It take a three days to declare result of that exam which you have on your email just because it takes time to evaluate the performance of candidates.

Evaluation of Old Format 
Now a days a big among students is that there is another exam RHCT required to take but according to new format of Rad Hat it replaced by RHCSA , a prerequisite for RHCE ( Red Hat Certified Engineer ) so want to choose that path prepare for that as I always saying it shining in your resume as a star whether you are a fresher or experienced
