What is the purpose of the Cisco DNA Center controller?

Cisco DNA Center is a centralized network controller that provides a single pane of glass for managing, automating, and securing an entire network infrastructure. Its primary purpose is to securely manage and deploy network devices by offering features like automated device provisioning, policy-based automation, and network assurance. It simplifies network operations and enhances security through consistent policy enforcement. Incorrect options: Scanning a network and generating a Layer 2 diagram is a function of network monitoring tools, not the primary purpose of DNA Center. While DNA Center can visualize network topology, it's part of a broader management role. Securing physical access to a data center is a physical security concern, unrelated to DNA Center's software-defined networking role. Providing Layer 3 services to autonomous access points is typically handled by network devices like routers and switches, not directly by a network controller like DNA Center, which focuses on orchestrating these devices.
