Beginners can use Cisco Packet Tracer, GNS3, and EVE-NG to practice CCNA concepts in virtual environments. These tools help learners create network topologies, configure routers and switches, and understand how devices communicate. FITA Academy emphasizes practical networking knowledge, making hands-on simulation useful for understanding concepts beyond theory. Packet Tracer is particularly suitable for beginners, while GNS3 and EVE-NG can support more advanced networking practice.
