What is a network engineer?

 First of all, let's define the terms. A network engineer is a specialist responsible for creating, configuring and maintaining the company's internal computer networks, as well as for interacting the company's IT infrastructure with external networks. "Networkers" must have a serious level of knowledge in the field of design and maintenance of networks, but their work will include elements of server administration and programming.

It is required to understand local networks, equipment and software solutions used in the company to manage the network component of IT systems. All this is provided only by a high level of qualifications of a network specialist: gaps in education and practical experience can be very expensive for a company, and given the depth of integration of business processes in a digital environment, the scale of potential losses is sometimes difficult to imagine, and it is better to avoid them even in theory ...

The value of certification

The development of any career depends on a specific person, in particular on awareness of choice, focus on results and readiness for difficulties. When building a career in the IT field, it is worth highlighting priority areas and tasks. I started my self-education process with a successful career in a completely different field, not related to IT and telecommunications.

The first, intermediate, goal on the career path of a network engineer can be called the certification of one or more vendors of network equipment. If we consider the most popular vendor, then gaining knowledge at the CCNA level (the first level in the Cisco certification system) is an objective entry barrier for working as a network engineer.

This certification does not indicate a specific level of knowledge, but indicates a basic understanding of working with network equipment. For people who are just starting a career with no work experience, having a certificate can be a good help when applying for a job.

Taking a CCNA course on the basis of one of the training centers gives certain knowledge, but from the point of view of the experience gained, the maximum result can be obtained only with the already existing knowledge, by structuring it on the course and receiving answers to already formed questions. A lot depends on the teacher on the course, it is worth looking for a teacher not only with his own high qualifications, but also with good teaching skills.
