The best resolution for an organization that implements Network Access Control (NAC) using IEEE 802.1x and discovers the printers do not support the IEEE 802.1x standard is to install an IEEE 802.1x bridge for the printers. IEEE 802.1x is a standard that provides port-based authentication for network devices, such as switches, routers, or wireless access points. IEEE 802.1x allows only authorized devices to access the network, based on their credentials or certificates. However, some devices, such as printers, may not support IEEE
802.1x or have the required credentials or certificates. In this case, an IEEE 802.1x bridge can be used to connect the printers to the network. An IEEE 802.1x bridge is a device that acts as a proxy for the printers and performs the IEEE 802.1x authentication on their behalf. The bridge can also isolate the printers from the rest of the network and apply security policies to them. References: CISSP All-in-One Exam Guide, Chapter 4:
