CCNAv7: 1 - Introduction to Networks (ITN)

CCNAv7: 1 - Introduction to Networks (ITN) covers the architecture, structure, functions and components of the Internet and other computer networks. Students achieve a basic understanding of how networks operate and how to build simple local area networks (LAN), perform basic configurations for routers and switches, and implement Internet Protocol (IP).


By the end of the course, students will be able to:

  • Configure switches and end devices to provide access to local and remote network resources

  • Explain how physical and data link layer protocols support the operation of Ethernet in a switched network

  • Configure routers to enable end-to-end connectivity between remote devices

  • Create IPv4 and IPv6 addressing schemes and verify network connectivity between devices

  • Explain how the upper layers of the OSI model support network applications

  • Configure a small network with security best practices

  • Troubleshoot connectivity in a small network


The course is the 1st of 3 courses in the Cisco CCNAv7 curriculum and includes activities using Packet Tracer, hands-on lab work, and a wide array of assessment types and tools.


There are no formal prerequisites for the new CCNA certification, but you should have an understanding of the exam topics before taking the exam.

CCNA candidates often also have:

  • One or more years of experience implementing and administering Cisco solutions

  • Knowledge of basic IP addressing

  • A good understanding of network fundamentals


Anyone who desires a practical and technical introduction to the field of networking. Job roles include headend technicians, network operations centre (NOC) staff, network engineers, network administrators, and network help-desk staff.
