Professional certification, trade certification, or professional designation, often called simply certification or qualification, is a designation earned by a person to assure qualification to perform a job or task.
The certificate alone wont get you a job, but it might get you a interview at the least. Anyone can read a book or watch some videos online to study for a test/exam, but you need to show that you are proficient in the subject, meaning that you can solve real world problems and not just answer test questions. The CCNA is really just to get you to the interview and then you sell yourself to get the job.
