Enterprise Networking, Security, and Automation is the 3rd of 3 courses in the Cisco Certified Network Associate (CCNA) curriculum. The course describes the architectures and considerations related to designing, securing, operating and troubleshooting enterprise networks. The 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.
Configure and troubleshoot Single-area Open Shortest Path First (OSPFv2) to operate in both point-to-point and multi access networks. Explain how vulnerabilities, threats and exploits can be mitigated to enhance network security. Implement Internet Protocol (IPv4) Access Control Lists (ACLs) to filter traffic and secure administrative access. Configure Network Address Translation (NAT) services on the edge router to provide IPv4 address scalability. Explain how WAN access technologies can be used to satisfy business requirements. Explain how Virtual Private Networks (VPNs) secure site-to-site and remote access connectivity. Explain how networking devices implement QoS. Implement protocols to manage the network. Explain the characteristics of scalable network architectures. Troubleshoot enterprise networks. Explain the purpose and characteristics of network virtualization. Explain how network automation is enabled through Representational State Transfer (RESTful) APIs and configuration management tools.
