350-401 Question 56
Select 2An organization is planning to integrate their traditional campus network with Cisco SD-Access. The traditional network uses VLANs for segmentation, while the SD-Access fabric uses Virtual Networks (VNs) for segmentation. What is a necessary step to ensure proper communication between the two environments?
- A
Configure a Layer 3 handoff between the SD-Access border node and the traditional network.
- B
Implement VXLAN encapsulation on the traditional campus network to match the SD-Access fabric.
- C
Map VLANs from the traditional network to Virtual Networks (VNs) in the SD-Access fabric.
- D
Deploy a policy-based control plane to enforce segmentation across both environments.
- E
Ensure that the SD-Access control plane node has direct Layer 2 adjacency with the traditional network.
Show answer and explanation
Correct answers: A, C
Explanation
To integrate a traditional campus network with an SD-Access fabric, a Layer 3 handoff is necessary to route traffic between the two environments. Additionally, VLANs in the traditional network need to be mapped to Virtual Networks (VNs) in the SD-Access fabric to maintain segmentation consistency and ensure end-to-end communication.
- A. Correct.
Correct. A Layer 3 handoff is required to allow routing between the SD-Access fabric and the traditional campus network. This is typically configured on the SD-Access border node.
- B. Incorrect.
Incorrect. VXLAN encapsulation is native to the SD-Access fabric and is not required on the traditional network. The traditional network operates using standard VLANs.
- C. Correct.
Correct. VLANs in the traditional network must be mapped to the appropriate Virtual Networks (VNs) in the SD-Access fabric to maintain segmentation and ensure proper traffic flow.
- D. Incorrect.
Incorrect. While policy-based control can be implemented within the SD-Access fabric, it does not directly enable communication between the SD-Access and traditional network environments.
- E. Incorrect.
Incorrect. Layer 2 adjacency between the SD-Access control plane node and the traditional network is not required. Communication is typically facilitated via Layer 3 handoff at the border node.
