The third and final course in the CCNA series — master enterprise network design, security, WAN technologies, and network automation to complete your path to CCNA certification.
CCNA: Enterprise Networking, Security, and Automation 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. It also introduces software-defined networking, virtualization, and automation concepts that support the digitalization of networks. Students gain skills to configure and troubleshoot enterprise networks, identify and protect against cybersecurity threats, and learn key concepts of software-defined networking including controller-based architectures and how APIs enable network automation.
