The curriculum for CCNA is comprehensive and includes four separate modules. The learning objectives of the CCNA certification exam, which is the first step in a Cisco career certification path, are covered in these modules. The curriculum places emphasis on the use of problem-solving techniques and decision-making to resolve networking issues.

Students train to use different protocols to mount and customise Cisco switches and routers on local and broad-area networks. They also train to provide Level 1 troubleshooting and increase the efficiency and reliability of the network. In addition, instruction is provided to assist the student in taking good care of, managing, and using software and equipment for networking.

In the CCNA certification course, which is taught mainly at secondary and post-secondary levels, the following modules are Networking Fundamentals, Routers and Routing Basics, Switching Basics and Intermediate Routing and WAN Technologies.

The Networking Basics module includes subjects such as Ethernet hardware basics, LAN and WAN cabling, TCP/IP and IP addressing basics, and routing basics. Themes such as the fundamentals of configuring routers, routing protocols, TCP/IP principles, access control lists, and networking troubleshooting skills are discussed in the Routers and Routing Basics module. Information of switching principles and setup and spanning-tree protocol are presented in the Switching Basics and Intermediate Routing module, while the WAN Technologies module discusses many topics, including frame relay.

CCNA coursework helps students study for CCNA certification, and may be chosen for the Introduction to Cisco Networking Technology (INTRO) and Interconnecting Cisco Networking Devices (ICND) tests as a single thorough review or as a two-part path. The former course is a recommended training course for individuals pursuing understanding and awareness of the foundations of networking, including the seven-layer architecture principles, vocabulary, and technology of open networks interconnect (OSI). The latter course, ICND, focuses on the use of Cisco catalyst switches and Cisco routers connecting to local area (LAN) and wide area (WAN) networks usually located on small to medium network sites.

Cisco certification validates the achievement of an individual and thus increases the professional credibility of the individual in the fundamentals of networking. The course is highly regarded in the industry and everyone who intends to make a career in networking should take up the course.
