Which function does a fabric edge node perform in an SD-Access deployment?
- A. Connects endpoints to the fabric and forwards their traffic.
- B. Encapsulates end-user data traffic into LISP.
- C. Connects the SD-Access fabric to another fabric or external Layer 3 networks.
- D. Provides reachability between border nodes in the fabric underlay.
Explanation: There are five basic device roles in the fabric overlay:
+ Control plane node: This node contains the settings, protocols, and mapping tables to provide the endpoint-to-location (EID-to-RLOC) mapping system for the fabric overlay.
+ Fabric border node: This fabric device (for example, core layer device) connects external Layer 3 networks to the SDA fabric.
+ Fabric edge node: This fabric device (for example, access or distribution layer device) connects wired endpoints to the SDA fabric.
+ Fabric WLAN controller (WLC): This fabric device connects APs and wireless endpoints to the SDA fabric.
+ Intermediate nodes: These are intermediate routers or extended switches that do not provide any sort of SD-Access fabric role other than underlay services.
