CISCO CERTIFIED NETWORK ADMINISTRATOR

This course introduces the architecture, structure, functions, components, and models of the Internet and other computer networks. It uses the OSI and TCP layered models to examine the nature and roles of protocols and services at the application, network, data link, and physical layers. The principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the curriculum.

As the first CCNA module, a mixture of equipment-based labs and simulations are used to allow participants to analyse real data without affecting production networks. Participants analyse protocol and network operation and build small networks in a simulated environment.

At the end of the course, participants build simple LAN topologies by applying basic principles of cabling; performing basic configurations of network devices, including routers and switches; and implementing IP addressing schemes.

Upon completion of the Network Fundamentals course, participants will be able to perform the following tasks:

  • Describe the importance and operation of data networks and the Internet in supporting communications
  • Recognise the devices and services that are used to support communications across an Internetwork
  • Use layered network protocol models to explain communication in data networks
  • Describe the importance of addressing and naming schemes at various layers of data networks
  • Describe the protocols and services provided by the Application layer in the OSI and TCP/IP models
  • Analyse the operations and features of the protocols and services at the Transport, Network and Data Link layers
  • Describe the fundamental concepts of routing
  • Design, calculate, and apply subnet masks and addresses to fulfill given requirements
  • Explain the role of Physical layer protocols and services in supporting communications across data networks

  • Utilise common network utilities to verify small network operations and analyse data traffic.

ROUTING PROTOCOLS AND CONCEPTS

This course describes the architecture, components, and operation of routers, and explains the principles of routing and routing protocols. Participants analyse, configure, verify, and troubleshoot the primary routing protocols RIPv1, RIPv2, EIGRP, and OSPF.

By the end of this course, delegates will be able to recognise and correct common routing issues and problems. Each chapter walks the student through a basic procedural lab, and then presents basic configuration, implementation, and troubleshooting labs.
