Overview of Cisco DNA Center
Cisco DNA Center is a topic that appears on the newly announced CCNA 200-301 exam (to be released Feb. 24, 2020). At the time of this recording, Cisco's DevNet Sandbox makes a couple of Cisco DNA Servers available for you to explore for free (without needing to set up a VPN connection). One server gives you read-write access, while the other gives you read-only access. Below are the links and login credentials:
