If there is one basic measure of competency for network professionals, it is the Cisco Certified Network Associate certification, commonly abbreviated CCNA. Individuals who carry this certification have demonstrated the required competency to serve as network administrators, have shown that they have a solid grasp of how networking works and have put themselves on the road toward getting more advanced degrees.

Cisco Systems constitutes one of the largest manufacturers of network hardware and software. Even where the major software vendor's products are found being used as the server operating system, much of the hardware will be found to be manufactured by Cisco and the networking technologies developed by Cisco are industry-standard. Knowledge of their systems is a starting point for any career in networking, no matter what other certifications may eventually be sought by the network technician.

As comprehensive as the CCNA certification is, there is no advanced knowledge required to obtain it. The CCNA certification is commonly sought by those taking their first steps into the networking world. One need not have years of on-the-job networking experience to understand the materials or even have much prior experience with computers in general. This is a vendor-neutral certification which means that the knowledge obtained applies to the basic function of the technology, not that technology as utilized by one manufacturer's products.

The basics of networking, including Ethernet, access lists, IP, RIP, VLANs, Serial and Frame Relay are all covered by this exam. Anyone who takes these courses will eliminate a great deal of the trial and error generally involved in learning networking on-the-job and can potentially save their company a great deal of money by eliminating the need for most service calls. Though this may be an entry-level certification, the usefulness of the skills obtained to any company or individual are potentially endless.

For employers looking for a way to inexpensively expand the capabilities of their IT department, CCNA training is an excellent way to start. If the training proves beneficial, other certifications such as the Cisco Certified Network Professional and the Cisco Certified Design Professional may be offered to the employee, either of which constitutes a significant increase in skills and knowledge.

Though this is the most basic of Cisco certifications, the exam is not easy. For the vast majority of technicians, training will be required to prepare for the test. This certification's popularity means that training is available from many sources. There are endless options online as well as many physical locations at which this certification is offered. The testing can be done in two parts or in one combined test. The certification is valid for three years. If the certified individual wishes to retain the certification, the tests must be retaken. Oftentimes, owing to changes in technology, training must be sought again, as well.

For individuals who are serious about a career in networking, the vendor-neutral nature of this certification makes it the best starting point for a potentially lucrative career in networking.
