What Is CCNA? - Computers

The CCNA is considered the entry level certification from Cisco . Technically, it has been replaced by the CCENT as the entry level certification but since the CCENT makes up half of the CCNA curriculum most employers still consider the CCNA the starting point for network certification when looking at job applicants. The CCNA program has been around for over a decade and is considered the gold standard when it comes to computer network certifications. For the most part, employers appreciate the CCNA as it involves learning a great deal about the basics of network models involving routing and switching. In fact, most experienced network engineers and administrators consider the CCNA a challenging certification to achieve at almost any skill level.

The CCNA can be quite a challenge if the candidate has had no preceding knowledge involving computer networks or routing and switching. The fact is that the CCNA can viewed practically as a mid-level test in comparison to some other distributors entry level tests on the market today. The range of topics that comprise the CCNA exam can be daunting if not broken down into sections. Even the most experienced network engineer needs to study voraciously in order to pass the exam. The CCNA is made up of two exams called ICDN1 and ICDN2. ICND1 is more of an introduction to basic networking including topics like the OSI model, TCP/IP, cabling and an overview of Ethernet. Passing the ICDN1 exam by itself grants the applicant CCENT status. ICND2 involves more complicated routing and switching subjects such as routing protocols like OSPF and EIGRP. IP subnetting is heavily covered as well as an overview of IPv6 basics. Switching methodologies covered include VLANS, VTP and a medium d ive into the workings of Spanning Tree Protocol as well as the basics of wireless mediums and network security.

The CCNA can also be taken as one test that encompasses both the ICDN1 and ICND2 exams. Many people have a preference over whether it is best to take the exams individually or as one bulk exam. The pro to taking the tests individually is that it allows the candidate to concentrate their study only on the aspects of either ICND1 or ICND2. The con to taking the tests individually is that you have to take 2 fifty-plus questions exams compared to one fifty plus question exam if you take the CCNA exam as a whole. The candidates' grasp of the material and study habits should indicate which the better path to take towards CCNA certification is.

Win asking what is CCNA and if it is right for you, a candidate will need to consider if they are looking to either start a career in computer networking or if they are looking for advancement within their current job position. As stated earlier, the CCNA is considered the de-facto standard certification for computer network jobs involving routing and switching. It is also one of the most challenging entry level certifications one can achieve from a third party vendor so research carefully if you think the certification will help reach your career goals.

In any case, if a candidate is intent on advancing themselves in the field of computer networking that requires routing and switching (and all networks require one form or the other, or both) the CCNA should be considered a must-have qualification as it is sought after by employers around the world.
