300-435 Question 176
Select 3An enterprise plans to deploy Cisco Software-Defined Access (SDA) to simplify network management and enhance security. The network administrator needs to configure the Fabric Edge nodes to ensure endpoint communication and policy enforcement. Which of the following are key responsibilities of the Fabric Edge nodes in the SDA architecture?
- A
Register endpoints to the control plane node
- B
Enforce security policies for endpoints
- C
Act as the central repository for endpoint-to-IP mapping
- D
Forward data traffic based on VXLAN encapsulation
- E
Provide external connectivity to non-SDA networks
Show answer and explanation
Correct answers: A, B, D
Explanation
Fabric Edge nodes play a critical role in SDA by registering endpoints to the control plane, enforcing security policies, and forwarding data traffic using VXLAN encapsulation. These functions enable SDA to simplify network management and enhance security through segmentation and policy-based control. However, external connectivity and central endpoint mapping are responsibilities of other components, like Border nodes and Control Plane nodes respectively.
- A. Correct.
Fabric Edge nodes are responsible for registering endpoints to the control plane node to ensure they can participate in SDA communication.
- B. Correct.
Fabric Edge nodes enforce security policies for endpoints as part of SDA's segmentation and policy framework.
- C. Incorrect.
The control plane node, not the Fabric Edge, acts as the central repository for endpoint-to-IP mapping in SDA.
- D. Correct.
Fabric Edge nodes forward data traffic based on VXLAN encapsulation, which is the core data-plane technology used in SDA.
- E. Incorrect.
Border nodes, not Fabric Edge nodes, are responsible for providing external connectivity to non-SDA networks.
