CCNA Course outline has been revised since 2019 after a new course update. As in this course Cisco removed a few topics and added the latest concept like Automation, Security, Layer II, Layer III redundancy protocols. Removed RIP, RIP Version2 and EIGRP, as no more the part of ccna course.

Before 2019, there were 12 types of CCNA Certification, like ccna security, ccna routing and switching, ccna wireless, ccna voice, ccna design etc. Now only single ccna 200-301 with course outline as covering the all aspect that has been removed almost. CCNA Security has a lot of concepts added in the course in Module III ENSA.

CCNA Cisco Certified Network Associate has major 3 books as per cisco netacad.

1-      CCNAv7: Introduction to Networks (ITN)

This module covers the Basic configuration of Cisco Router and switches in Chapter No. 2. Also whole books cover OSI Model briefly. Now in this course, Cisco improves the contents and more neatly classifies the IP Address and Layer 3 address in chapters. We can see the Number Systems is the separate chapter whereas the IPv4 and IPv6 are also separate. Secondly Network Layer is a separate chapter. So as I mentioned that the cisco ccna course in this format we have the brief data to read for all cisco ccna students as well as the cisco trainers. We have a separate chapter for each layer of OSI Model, We also can see the comparison with OSI Model and TCP/IP Model.

2-      CCNAv7: Switching, Routing, and Wireless Essentials (SRWE)

In this book, We can see the title as routing, switching, obviously clear cover the Layer II protocols like VLAN(Virtual Local Area Network), InterVLAN Routing using router on a stick, per VLAN per router interface, layer III switch , Ether Channel , First Hop Redundancy Protocol, LAN Security , Layer II Layer Security Concepts, WLAN Concepts and Configuration with WLAN Controllers, and end the book with Static routes and its troubleshooting.

3-      CCNAv7: Enterprise Networking, Security, and Automation (ENSA)

This module covers the OSPF Open Shortest Path First Routing Protocol with theory and configuration. Very important concept of ACL Access Control List with ACL types, Named ACL and Numbered ACL. Configuration Implementation of ACL. This is the basics and start of Cisco Firewall. NAT Network Address Translation is still part of Cisco Certified Network Associate course till today. Configuration of VPNs & IPsec (as IP is not secure and connectionless protocol) are used to secure site-to-site and remote access connectivity. QoS and Network Design, Network Management and Network Troubleshooting. Newly added Network Virtualization is now a part of the new Cisco CCNA Course. Very advanced concept of network automation is enabled through RESTful APIs and configuration management tools.
