Working toward a network administrator role does not require buying an expensive course first. The honest path is to build solid networking fundamentals, then add vendor depth, using genuinely free videos, simulators, and official objectives. The only hard cost is the exam fee if and when you choose to certify. Certifications are optional milestones that mark progress, not requirements to get hired. This study plan leads with free learning, frames time as a range based on your background and weekly hours, and keeps every claim grounded in occupation context rather than promises about hiring or outcomes.
Key takeaways
- Learn in order: vendor-neutral networking fundamentals first (Network+), then vendor depth with Cisco CCNA.
- Free resources like Professor Messer, free network simulators and emulators, freeCodeCamp, and Cisco's free learning materials cover most studying.
- Your only hard cost is the exam fee; an exam-only floor is about $300 for the CCNA, with Network+ around $399.
- Network+ and CCNA are optional milestones, never a requirement to start working in networking.
- Time to readiness is a range that depends on your starting point and weekly study hours, not a fixed timeline.
What to learn, in order
Start with vendor-neutral networking fundamentals: addressing and subnetting, the OSI model, switching and routing concepts, DNS, and common protocols. Critical thinking, reading comprehension, listening, and monitoring are core skills for the network administrator role, so practice diagnosing problems methodically and documenting what you observe. Layer in everyday admin tasks: troubleshooting connectivity, basic monitoring, and backups. A practical sequence is networking fundamentals (CompTIA Network+ objectives) first, then Cisco CCNA for hands-on vendor depth in configuration and routing. The published exam objectives for each are free and make an excellent structured syllabus you can work through at your own pace before deciding to certify.
How much does it cost to study for network administration?
Networking is well served by free learning. Professor Messer offers a complete free Network+ video course; free network simulators and emulators let you build and configure real topologies without buying hardware; freeCodeCamp covers fundamentals; and Cisco publishes free learning materials. The official exam objectives are free and double as a checklist. The only hard cost is the exam fee if you choose to certify. As an exam-only floor, the CCNA exam is roughly $300 and the Network+ exam roughly $399. Paid instructor-led training exists and can run into the thousands, with CCNA training around $4,195, but it is optional, not the plan.
How long it takes (it depends)
There is no honest fixed timeline, because how long it takes depends on your background and weekly study hours. Someone with prior IT or help-desk experience may move through fundamentals faster, while a complete beginner reasonably needs longer, especially for subnetting and routing. More hours per week shorten the calendar; fewer stretch it out. Rather than chasing a deadline, study consistently and build topologies in a free simulator so concepts become second nature. Use the official objectives to gauge readiness, then sit an exam only when you consistently meet them. Certifications are optional checkpoints, never required to begin applying for entry networking roles.
Frequently asked questions
Do I have to pay for a training course to study networking?
No. You can learn the core material for free using Professor Messer's free Network+ videos, free network simulators and emulators for hands-on practice, freeCodeCamp, Cisco's free learning materials, and the official exam objectives as a syllabus. Paid instructor-led training exists and can run into the thousands, with CCNA training around $4,195, but it is optional. The only hard cost in a free-first plan is the exam fee if you choose to certify.
Which certification should I get first?
A common order is vendor-neutral networking fundamentals first (CompTIA Network+), then Cisco CCNA for vendor depth. That said, certifications are optional milestones, not requirements to get hired, so let your goals and current knowledge guide the choice. Study from the free objectives, practice in a simulator, and certify when your knowledge is ready rather than rushing toward a credential.
How long does this study plan take?
It depends on your background and weekly study hours, so we will not invent a fixed timeline. People with prior IT experience often move faster through fundamentals; complete beginners reasonably take longer, particularly on subnetting and routing. More hours per week shorten the calendar; fewer stretch it out. Practice in a simulator, measure yourself against the official objectives, and sit an exam only when you consistently meet them.
Can I really do this for free?
Almost entirely, yes. The learning itself can be free through Professor Messer, free network simulators and emulators, freeCodeCamp, Cisco's free learning materials, and the official objectives. The one unavoidable cost is the exam fee if you decide to certify; as an exam-only floor, the CCNA is roughly $300 and Network+ roughly $399. You can study for free as long as you need and pay only when you choose to test.
