350-401 Exam - Question 797


Which two functions is an edge node responsible for? (Choose two.)

Show Answer
Correct Answer: AB

An edge node in a network is responsible for authenticating endpoints, ensuring that only authorized devices are allowed on the network, and providing the default entry point for fabric traffic. The edge node performs encapsulation and de-encapsulation of data traffic to and from connected endpoints, making it the main gateway for traffic entering the fabric.

A 100% is correct , per book . C is also seems right . Edge node is an xTR that provides, provides onboarding and mobility services for wired users and devices (including fabric-enabled WLCs and APs) connected to the fabric.

I prefer C over B because of this: VXLAN encapsulation/de-encapsulation Packets and frames received from endpoint... are encapsulated in fabric VXLAN and forwarded across the overlay. When fabric encapsulated traffic is received for the endpoint... it is de-encapsulated and sent to that endpoint. https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html

Edge Node provides first-hop services for Users / Devices connected to a Fabric [A] • Responsible for Identifying and Authenticating Endpoints (e.g. Static, 802.1X, Active Directory) [B] • Performs encapsulation / de-encapsulation of data traffic to and from all connected Endpoints https://www.cisco.com/c/dam/m/hr_hr/training-events/2019/cisco-connect/pdf/VH-Cisco-SD-Access-Connecting.pdf

A. is definitely correct but C is explained below. A fabric edge performs the encap and decap of host traffic to and from its connected endpoints. CCNP ENCOR Cert guide - p.623

i would choose A & B. For me C could not be because not provide exit points, the exits points are edge border nodes

Answer is wrong. Should be C and E

A. fabric edge first identifies and authenticates wired endpoints (through 802.1x), in order to place them in a host pool (SVI and VRF instance) and scalable group (SGT assignment). It then registers the specific EID host address (that is, MAC, /32 IPv4, or /128 IPv6) with the control plane node. B. It's next-hop VTEP for hosts !=C. The control plane (host database) maps all EID locations to the current fabric edge or border node.

Going with A & B CCNP Book: Fabric Edge Nodes A fabric edge node provides onboarding and mobility services for wired users and devices (including fabric-enabled WLCs and APs) connected to the fabric. It is a LISP tunnel router (xTR) that also provides the anycast gateway, endpoint authentication.. A is clear "A fabric edge first identifies and authenticates wired endpoints (through 802.1x), in order to place them in a host pool (SVI and VRF instance) and scalable group (SGT assignment). Based on below i would say B is also clear: A fabric edge provides a single Layer 3 anycast gateway (that is, the same SVI with the same IP address on all fabric edge nodes) for its connected endpoints and also performs the encapsulation and de-encapsulation of host traffic to and from its connected endpoints.
