At which layer of the open systems interconnection (OSI) model does network access control (NAC) typically operate? Select the best answer

Network access control (NAC) typically operates at layer 2, the data link layer, of the open systems interconnection (OSI) model. The data link layer is responsible for transferring data between adjacent nodes on a network, such as switches and endpoints. NAC operates at this layer by inspecting and controlling the access of devices to the network based on their MAC addresses, device profiles, security posture, and compliance status.
