CCNA: Enterprise Networking, Security, and Automation


Set Your Sights on a Networking Career


Large enterprises depend heavily on the smooth operation of their network infrastructures. This final course in the CCNA series describes the architectures and considerations related to designing, securing, operating, and troubleshooting enterprise networks. It 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.

Course Overview

CCNA 7: Enterprise Networking, Security, and Automation (ENSA) describes the architecture, components, operations, and security to scale for large, complex networks, including wide area network (WAN) technologies. The course emphasizes network security concepts and introduces network virtualization and automation. Students learn how to configure, troubleshoot, and secure enterprise network devices and understand how application programming interfaces (API) and configuration management tools enable network automation.

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

  • Configure single-area OSPFv2 in both point-to-point and multiaccess networks.
  • Explain how to mitigate threats and enhance network security using access control lists and security best practices.
  • Implement standard IPv4 ACLs to filter traffic and secure administrative access.
  • Configure NAT services on the edge router to provide IPv4 address scalability.
  • Explain techniques to provide address scalability and secure remote access for WANs.
  • Explain how to optimize, monitor, and troubleshoot scalable network architectures.
  • Explain how networking devices implement QoS.
  • Implement protocols to manage the network.
  • Explain how technologies such as virtualization, software defined networking, and automation affect evolving networks.
