Overview
What this course covers.
The CCNA program builds real networking competence from the ground up - not just exam answers. You will work hands-on with routers, switches, and live network topologies to understand how traffic actually moves across a network.
By the end of the course, you will be able to design, configure, and troubleshoot small to medium-sized networks, and you will be fully prepared to sit the official Cisco CCNA certification exam.
This course is built for students, IT support staff, and anyone starting a career in networking or infrastructure.

01 Networking Fundamentals 5 lessons
- Anatomy of a Network How data actually travels: devices, topologies, and the physical/logical layers that make networks work.
- The OSI & TCP/IP Models, Decoded Map real traffic to each layer so troubleshooting stops being guesswork.
- Ethernet, Cabling & Physical Layer Copper vs fiber, duplex mismatches, and diagnosing the problems that live below Layer 3.
- IPv4 Addressing & Subnetting Mastery Subnet on paper and in your head - the exact skill every networking interview tests first.
- IPv6 for the Modern Network Address types, notation, and why every serious network is migrating now.
02 Network Access & Switching 5 lessons
- Switching Internals MAC address tables, frame forwarding, and why broadcast storms happen.
- VLANs & 802.1Q Trunking Segment a flat network into secure, purpose-built zones.
- Inter-VLAN Routing Router-on-a-stick and Layer 3 switching, configured and verified.
- Spanning Tree Protocol Kill Layer 2 loops before they take down a network.
- EtherChannel & Link Redundancy Bundle links for bandwidth and zero-downtime failover.
03 IP Connectivity & Routing 4 lessons
- Routing Table Deep Dive How a router actually decides where a packet goes next.
- Static Routing, Configured Right Build predictable paths and troubleshoot when they break.
- OSPF Single-Area in Practice Stand up dynamic routing that scales beyond static tables.
- First-Hop Redundancy with HSRP Keep the gateway alive even when a router isn't.
04 IP Services 4 lessons
- DHCP & DNS, End to End Automatic addressing and name resolution - the services every network silently depends on.
- NAT in the Real World Translate private networks to the internet without breaking anything.
- NTP & Syslog for Real Troubleshooting Time-sync devices and read logs like an engineer, not a guesser.
- QoS Fundamentals Prioritize traffic before congestion becomes an outage.
05 Security Fundamentals 4 lessons
- Network Threats & Defense-in-Depth What attackers target first, and how layered defense stops them.
- Access Control Lists, Written Correctly Standard vs extended ACLs, and the mistakes that lock out the wrong traffic.
- Port Security & Device Hardening Lock down switch ports and close the doors attackers walk through.
- VPN & Wireless Security Essentials Site-to-site VPN concepts and WPA-secured wireless, explained practically.
06 Automation & Exam Readiness 3 lessons
- Intro to Network Automation SDN, APIs, and why manual CLI work is being replaced.
- Full Packet Tracer Lab Review Every topic so far, tied together in one hands-on simulation.
- CCNA Exam Blueprint & Strategy Exam format, timing, and how to approach the questions that trip people up.
