What is the purpose of the Cisco DNA Center controller?

to securely manage and deploy network devices. Wireless design and security require separating AP mode, WLAN identity, RF behavior, authentication, and encryption. Cisco CCNA 200-301 v1.1 includes this under Automation and Programmability, where the expected skill is identifying the mechanism that actually satisfies the scenario. The wording usually gives the decisive clue: a protocol number, a route prefix, a control-plane role, a wireless security method, or a management command. The distractors confuse wireless standards, security mechanisms, controller settings, or RF design practices. In a real network, selecting the wrong option would usually produce a failed adjacency, broken client connectivity, insecure management access, or an incorrect forwarding path. The selected answer matches the Cisco behavior and configuration model required by the question, so it is retained as the verified answer for this item.
