350-401 Question 52
Select 3An enterprise network is deploying Cisco SD-Access and is configuring the control and data planes. The network administrator needs to ensure proper communication between fabric edge nodes and ensure that endpoint information is propagated correctly. Which control and data plane elements must be implemented to achieve this?
- A
LISP (Locator/ID Separation Protocol) for endpoint-to-location mapping
- B
VXLAN for data plane encapsulation
- C
OSPF for control plane routing
- D
Control Plane Node to manage endpoint registrations
- E
IPsec tunnel between fabric edge nodes for secure communication
Show answer and explanation
Correct answers: A, B, D
Explanation
Cisco SD-Access relies on specific control and data plane protocols and components to function. LISP is used as the control plane protocol to map endpoints to locations, VXLAN is used for data plane encapsulation, and the Control Plane Node is responsible for managing endpoint information. These elements ensure proper communication and scalability within the SD-Access fabric.
- A. Correct.
Correct. LISP is a key control plane protocol in Cisco SD-Access, used to map endpoints to their locations within the fabric.
- B. Correct.
Correct. VXLAN is the main data plane encapsulation protocol used in Cisco SD-Access to allow scalable Layer 2 and Layer 3 overlays.
- C. Incorrect.
Incorrect. OSPF is not used as the control plane protocol in SD-Access. LISP is used for endpoint-to-location mapping.
- D. Correct.
Correct. The Control Plane Node is essential for managing endpoint registrations and maintaining the mapping database of endpoints to fabric locations.
- E. Incorrect.
Incorrect. IPsec tunnels are not required between fabric edge nodes in SD-Access. VXLAN handles the encapsulation and transport of data within the fabric.
