CCNA Routing and Switching Crash course

Ace the Cisco 200-125 certification exam

Astrit Krasniqi

Technology is changing the way we communicate via machines. Skills required for a core network engineer are evolving to prepare for this network transition. The CCNA Routing and Switching certification will not only prepare you with the knowledge of foundational technologies, but ensure you stay relevant with skill sets needed for the adoption of next generation technologies. Cisco Certified Network Associate (CCNA) Routing and Switching is an international certification program for entry-level network engineers. This course will be an interactive session which will cover every topic that’s a part of the CCNA Routing and Switching exam. It will cover Network Fundamentals, LAN Switching, Routing and WAN technologies, Infrastructure Services, Infrastructure Security and Infrastructure Management.

This course will commence with “Introduction to Networks” that will introduce the principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations to provide a foundation for the curriculum. You will be able to understand network technologies, devices accessing local and remote network resources, and router hardware. Further on, we'll explore how to design an IP addressing scheme to provide network connectivity for a small to medium-sized business network.

Moving on, we'll explore Routing and Switching Essentials. You'll learn about architecture, components, and operations of routers and switches in a small network. You will be able to determine traffic forwarding via a router, based on the contents of a routing table, understand switches operations in a small to medium-sized business network, and be able to use monitoring tools and network management protocols to troubleshoot data networks. This training course will walk you through router and switch configuration for basic and advanced functionality. You will also learn the architecture, components, and operations of routers and switches in larger and more complex networks.

You will then be trained on WAN technologies and network services required by converged applications in a complex network. You will understand the selection criteria of network devices and WAN technologies to meet network requirements.

The final concepts in this session will focus on Infrastructure Services, Security and Management. Here, you will learn to configure, verify and troubleshoot NAT, HSRP, GRE tunnels, port security, traffic filtering. You will also understand Local SPAN, Cisco IOS tools to troubleshoot and resolve problems, configuration and verifying device management.

What you'll learn-and how you can apply it

  • Successfully install, operate, and troubleshoot a small to medium-size enterprise branch office network
  • LANs and WANs interconnection to the Internet
  • Accessing a Cisco IOS device for configuration purposes
