Cisco CCNA 200-301 Practice Question

Controller-based networking provides centralized management, allowing for automated configuration of network devices from a single controller. This centralization reduces the time and errors associated with configuring devices individually in a traditional network. Automation through the controller streamlines network management tasks such as deploying configurations, policies, and updates across multiple devices simultaneously. The other options are incorrect: requiring manual configuration of each device contradicts the benefit of centralization and automation; using proprietary protocols is not a defining feature of controller-based networks—they often utilize open standards; and while virtualization can be a component of modern networks, controller-based networking does not inherently replace physical devices but improves their management.
