Jul 27, 2026
This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Cisco DNA Center (Catalyst Center) acts as a centralized controller, replacing device-by-device CLI management with automation. - Intent-based networking allows you to define business outcomes (the 'what'), which DNA Center then translates into network configurations (the 'how'). - The underlay is the physical network providing basic connectivity, while the overlay is the virtual network (using VXLAN) that enforces policy in SD-Access. - DNA Center Assurance provides analytics and AI-driven insights to proactively monitor network health and accelerate troubleshooting. - Northbound APIs are used for integration, allowing external IT systems to programmatically interact with the network via DNA Center.
