OSI model, TCP/IP, IP addressing, subnetting, DNS, DHCP — the building blocks every network engineer must know cold.
By the end, you'll be able to
Mini-project
Design an IP addressing scheme for a company with 5 offices, 200 devices each. Include subnetting, VLANs, and a network diagram.
Recommended Resources
Get hands-on with Cisco routers. Learn IOS CLI, static/dynamic routing (OSPF, EIGRP, BGP), and how to troubleshoot routing issues.
By the end, you'll be able to
Mini-project
Build a lab in Packet Tracer: 3 routers, 5 networks, OSPF routing, with deliberate misconfigurations to troubleshoot.
Master layer 2: VLANs, trunking, STP, EtherChannel, and inter-VLAN routing. Switches are the foundation of every office network.
By the end, you'll be able to
Mini-project
Design a campus network: access/distribution/core switches, VLANs for departments, trunk links, and STP.
Secure the network: ACLs, firewalls, VPNs, port security, and 802.1X. Network security is critical — and pays premium salaries.
By the end, you'll be able to
Mini-project
Secure a network: ACLs to restrict traffic, VPN between two offices, port security on switches, and a firewall ruleset.
WiFi is everywhere. Learn wireless standards, controller-based architectures, site surveys, and enterprise WiFi deployment.
By the end, you'll be able to
Mini-project
Design a wireless network for a college campus: AP placement, channel planning, roaming, and guest access.
Networks are moving to the cloud. Learn VPCs, subnets, route tables, security groups, and hybrid connectivity (VPN, Direct Connect).
By the end, you'll be able to
Mini-project
Build a multi-VPC architecture in AWS: production, staging, shared services. Set up VPC peering and a VPN to an on-premises network.
CCNA is the most recognized networking certification in India. It validates your skills and significantly boosts your resume.
By the end, you'll be able to
Mini-project
Take 10 full-length CCNA practice exams. Build 20 labs covering all exam topics. Score 85%+ consistently.
The future of networking is code. Learn Python for network automation, Ansible for configuration management, and APIs for network devices.
By the end, you'll be able to
Mini-project
Write Python scripts to: backup configs from 10 devices, push VLAN changes across switches, and generate network reports.
