The modern workplace relies heavily on certifications and references and sometimes the employers’ tendency to demand piles of diplomas and certificates is taken to the extreme. However, there are some fields of activity where these papers really are necessary and where you cannot be proficient without following a specialized course. One of the most relevant examples is without a doubt networking, routing and switching. If you want to apply for a job in a company’s IT department and work on the above mentioned tasks, an interest in networking and vague experience will take you nowhere. To stay competitive and, of course, to polish your skills, you’ll have to consider CCNA classes. These aren’t only necessary because the certification you get at the end of the course brings more credibility, but also because they teach you essential things about a highly specialized field.
CCNA stands for Cisco Certified Network Associate and it’s a 2nd level certification provided by Cisco to trainees who successfully get a passing score at the Cisco exam. Needless to say, you’ll have to take CCNA classes for several weeks in order to qualify for the examination. The aim of the exam is to determine whether or not the candidate has sufficient knowledge about networking-related topics. This includes fundamental things that every IT professional should know, such as routing and switching or network types. In addition, since this is a second-level certification, the candidate also needs to be familiar with more advanced notions and tasks, such as network security implementation, IP traffic management and Frame Relay connections. There are two types of materials needed for CCNA exams: ICND1 and ICND2. You’ll need to know both if you want to get a passing score. When it comes to CCNA classes, it’s important to point out that the topics found in the exam often change, mostly due to the dynamic nature of the IT field.
So, if in most fields you can take an exam years after completing your education, because the subject stays pretty much the same, things work differently in IT. Fields such as networking are constantly evolving, which means that if you followed a course, say, ten years ago, some of the notions you picked up then may have become obsolete or incomplete in the meantime. Out of all work fields, IT requires its professionals to pursue continuous development and stay up to date with the latest technologies. This is why you have to take CCNA classes close to the date of the examination. Depending on the time passed since you got your certificate, some employers may ask their IT staff to take CCNA classes or other Cisco-approved classes to refresh their knowledge. The list of things you need to know about networking is quite extensive and includes many specialized notions, so you should be very serious about your training. The certificate is of course important, but, first and foremost, you have to go to the classes are essential because their help expand your professional horizon and develop your skills.
