How to become a Network Administrator from scratch?

In fact, a network administrator never finishes his or her training. Continuous studies are vital to keeping up to date in an industry that is constantly evolving and changing.

Final words

As you have already understood, there is a lot to learn. Meanwhile, the profession is very stressful – a kind of IT firefighter. You have to be a squirrel in a wheel: react to user complaints, solve a lot of problems, fix the printer, restore files, etc.

The other side is that it’s a good step to dive into the IT industry. There are lots of interesting tasks and people to interact with. It’s a good help for mastering other professions in development or DevOps. It may be worth putting up with the downsides and seeing more of the merits in systems administration for the sake of the experience.
