Network Administrator

As a network administrator you keep the digital backbone of an organization humming. One day you might be configuring VLANs for a new office wing, the next you’re troubleshooting a sudden outage that’s affecting remote workers. You’ll monitor traffic, apply patches, and document changes so that the network stays reliable and secure, all while juggling tickets from help‑desk staff and coordinating with server and security teams.

Employers value a blend of practical know‑how and solid fundamentals. They look for confidence with routing and switching protocols, the ability to script repetitive tasks, and a clear understanding of how operating systems interact with network services. Strong problem‑solving instincts, attention to detail, and good communication are just as critical as technical chops, because you’ll often have to explain issues to non‑technical colleagues and work across departments.

The certification path mirrors those expectations step by step. Starting with Certified IT Support Plus you master end‑user troubleshooting and basic networking concepts. Certified Network Plus deepens your knowledge of routing, switching, and network design. Certified Server Plus adds server‑side expertise, while Certified Security Plus equips you to protect the infrastructure. Finally, Certified Linux Plus rounds out your skill set with Linux networking and administration, giving you the confidence to manage diverse environments.
