8. Network Automation:

   • Basic understanding of network automation concepts, scripting languages (e.g., Python), and automation tools.

9. Troubleshooting Skills:

   • Strong troubleshooting skills to diagnose and resolve complex network issues efficiently.

10. Network Management:

    • Knowledge of network management tools and protocols for monitoring and managing network devices.

11. Quality of Service (QoS):

    • Understanding QoS mechanisms for prioritizing and managing network traffic.

12. Multicast Routing:

    • Familiarity with multicast routing protocols and configurations.

13. Documentation Skills:

    • The ability to create and understand network documentation, including network diagrams and configurations.

14. Virtualization Technologies:

    • Knowledge of virtualization technologies, such as VMware or Hyper-V, is beneficial, especially for tracks like CCIE Data Center.
