Intro
Our journey toward the CCNA starts from this introduction. Here, we will see what jobs await us in the Networking fields and why the CCNA Certification can help us get there. We will also have a high-level overview of what networking is, and why it is really needed. Check these articles to see if networking is really your thing!

- The ICT top players: vendor, provider and system integrator
- Be recognized: vendors certification programs
TCP/IP
CCNA starts with a solid understanding of networking concepts. With the articles in this section, you are going to understand how network works, following two famous way of representing them: OSI model and TCP/IP model.
- The OSI model: complex networks made simple
- Nothing but the bit: introduction to binary math
- Physical layer: signals, waves and transmission types
- Physical layer: copper media and ethernet cable
- Physical layer: fiber optic media, data as light pulses
- Physical layer: wireless media, Wi-Fi and more
- Interconnecting devices: the network topology
- The Data Link layer of the OSI model
- Network Layer: IPv4 Addressing and IPv4 Protocol
- Network Layer: The ultimate guide to IPv4 subnetting
- Network Layer: IPv6 addressing and IPv6 protocol
- The Transport Layer: TCP and UDP
- Transmission Control Protocol (TCP): The advanced stuff
- Session and Presentation layers in the OSI model
- Application layer and some popular protocols
- Protocols for the network: DNS, DHCP, Dynamic Routing
Configuration Fundamentals
Once you have the knowledge, we can to configure Cisco devices. In this section, we will see how to connect to routers and switches, and how to configure them. We will also introduce the most basic commands of the CCNA Routing & Switching.

Enterprise Services
CCNA is not just about routing and switching. Instead, it requires you to design, implement and scale networks. To create such a functional network, you need to know how to integrate with other systems. In this section, we will see how to configure DHCP, connect to the Internet, design a scalable network and use modern technologies.

Switching
In this section, we will present you the advanced concepts of switching for the CCNA. They include Spanning Tree, with tuning features, VTP, EtherChannels HSRP. With this knowledge, you will develop an high-available LAN.

Routing
The other key part of CCNA is Routing. In this section, we are going to see some in-depth concepts, spanning from OSPF to EIGRP, and with a basic introduction to BGP to connect to an Internet Provider.
- OSPF, All you need to know for the CCNA
- OSPF Configuration and Troubleshooting at CCNA level
- OSPFv6: Configuring OSPF for IPv6 on Cisco routers
- EIGRP, All You need to know for the CCNA
- EIGRP Configuration and Troubleshooting for the CCNA
