About the Course

The Network Administration course is designed for those who want to learn network technologies from scratch and work in a real business environment.

The course program covers topics from zero to expert level in the field of networking:

Network Fundamentals: OSI and TCP/IP models, cabling, IP addressing and IOS operating system.

Switching and Subnetting: Setting up VLANs, STP protocol and dividing networks into subnets (Subnetting/VLSM).

Routing: Static and dynamic routing protocols (OSPF, EIGRP, BGP), IPv6 configuration.

Security and Automation: Firewall basics, ACL, VPN technologies and network programming (SDN, REST APIs).

Multi-vendor Bonus: Students learn to work not only with Cisco, but also with MikroTik, HPE (Aruba) and Planet equipment.

🚀 What Will Students Get?

Students who successfully complete the course will have the following skills:

Professional Configuration: Install and manage routers and switches from various vendors (Cisco, MikroTik, HPE) from scratch.

Network Design: Understand hierarchical network design and design enterprise network infrastructure.

Troubleshooting: Diagnose and resolve network problems.

Security Skills: Apply necessary security rules (Port Security, ACL) to prevent external intrusions into the network.

Certification Preparation: Gather the necessary base for entry into international Cisco certification exams (e.g. CCNA).
