Our recommendation
David Bombal's popular networking course, a thorough introduction that also serves as a starting point for the Cisco CCNA. It covers TCP/IP, routing, switching and network security through hands-on labs. It is exam-adjacent prep — the CCNA certification is a separate, paid Cisco exam.
Good for: Beginners who want a thorough networking foundation, including towards the CCNA.
Less suitable if: You already know networking, or you do not want Cisco-focused depth.
Realistic time: About 79 hours; a couple of months part-time.
