A person with CCNA can become an admin of Network in Company to configure, troubleshoot and install devices of Cisco.

Initial Cisco’s Network Certifications

Initially, there was only one certified course in  Cisco Certification and that was CCIE(Cisco Certified Internet-work Expert).But it was too difficult to take attempt for that course directly, so the people giving exams needed to give lots of attempts for this examination.
So, after watching these all, Cisco permitted more number of course from initial stage to the CCIE level. This initial level of course is CCNA.

First step towards Cisco Certifications and Fee’s of CCNA

CCNA is the first step and the first course towards the certifications of Cisco. Cisco has organized one exam for CCNA certification. Fee’s for applying in that examination is 295$. So one must be properly trained, practiced and have referred the certain books on it to apply for this exam as the 295$ is not a small amount.

Validity of CCNA Certificate

The validity of CCNA is up to 3 years until you give the exam of next level which is CCNP(Cisco Certified Network Professional). So if one wants to appear for CCNP, he must appear within 3 years after completing the CCNA.
