Interconnecting Cisco Networking Devices: Accelerated (CCNAX) v3.0

What you’ll learn in this course

The Interconnecting Cisco Networking Devices: Accelerated (CCNAX) v3.0 course teaches you how to install, operate, configure, and verify a basic Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) network, including configuring a LAN switch, configuring an IP router, connecting to a WAN, and identifying basic security threats. You will also learn how to perform basic troubleshooting steps in enterprise branch office networks, as well as prepare for Cisco® Cisco Certified Network Associate (CCNA) certification.

The course covers the elements of Quality of Service (QoS) and their applicability, explores how virtualized and cloud services interact and impact enterprise networks, and provides an overview of network programmability with the related controller types and tools that are available to support Software-Defined Networking (SDN) architectures. You’ll also gain an understanding of the interactions and network functions of firewalls, wireless controllers, and access points, along with additional focus on IPv6 and basic network security.

This course consists of two courses merged into a single course: Interconnecting Cisco Networking Devices, Part 1 (ICND1) and Interconnecting Cisco Networking Devices, Part 2 (ICND2).

Course duration

  • Instructor-led training: 5 days with hands-on lab practice
