CCNAv7: Introduction to Networks (ITN) The first course in the CCNA curriculum introduces the architectures, models, protocols,
and networking elements that connect users, devices, applications and data through the Internet and across modern computer
networks - including IP addressing and Ethernet fundamentals. By the end of the course, students can build simple local area networks
(LAN) that integrate IP addressing schemes, foundational network security, and perform basic configurations for routers and switches.
CCNAv7: Switching, Routing, and Wireless Essentials (SRWE) The second course in the CCNA curriculum focuses on switching
technologies and router operations that support small-to-medium business networks and includes wireless local area networks (WLAN)
and security concepts. Students learn key switching and routing concepts. They can perform basic network configuration and
troubleshooting, identify and mitigate LAN security threats, and configure and secure a basic WLAN.
CCNAv7: Enterprise Networking, Security, and Automation (ENSA) The third course in the CCNA curriculum describes the
architectures and considerations related to designing, securing, operating, and troubleshooting enterprise networks. This course
covers wide area network (WAN) technologies and quality of service (QoS) mechanisms used for secure remote access along with the
introduction of software-defined networking, virtualization, and automation concepts that support the digitalization of networks. Students
gain skills to configure and troubleshoot enterprise networks, and learn to identify and protect against cybersecurity threats. They are
introduced to network management tools and learn key concepts of software-defined networking, including controller-based
architectures and how application programming interfaces (APIs) enable network automation.
