Which node serves as the gateway between the fabric domain and the known network outside of the fabric?
- intermediate node
- fabric border node
- default border node
- border node
Explanation: Fabric border nodes serve as the gateway between the Cisco SD-Access fabric site and the networks external to the fabric. They are responsible for network virtualization interworking, advertisement of EID subnets (typically using BGP), and SGT propagation from the fabric to the rest of the network. These nodes can be configured in different roles: an internal border connects to a well-defined/known set of IP subnets (such as a data center or shared services), while an external border serves as the gateway of last resort for unknown destinations outside the enterprise.
