Why each option
In Cisco SD-Access, key device roles include the Control Plane Node, Edge Node, and Border Node, each fulfilling a distinct function within the fabric.
The Control Plane Node in Cisco SD-Access hosts the LISP map-server and map-resolver, managing endpoint identity and location information for fabric-attached devices.
'Access routing device' describes a function that an Edge Node performs but is not a formally defined, specific device role within the Cisco SD-Access fabric architecture.
The Edge Node is a core SD-Access fabric role, typically a switch, responsible for connecting end-user devices and wireless access points to the fabric and implementing host onboarding.
The Border Node is an essential SD-Access fabric role that provides connectivity between the fabric and external networks, serving as the gateway for traffic leaving or entering the fabric.
'Distributed Node' is not a recognized or defined device role within the Cisco SD-Access fabric architecture.
