350-401 Question 54
Select 3An enterprise network is undergoing a migration where its traditional campus network needs to interoperate with Cisco SD-Access. The IT team wants to ensure seamless communication between devices in the legacy network and the SD-Access fabric. Which key considerations should the team focus on to enable interoperability?
- A
Configuring Border Nodes to connect the traditional campus to the SD-Access fabric
- B
Ensuring that the traditional campus network uses VXLAN encapsulation for data traffic
- C
Deploying a Control Plane Node to handle endpoint identification for the SD-Access fabric
- D
Using LISP to map endpoints between the traditional network and SD-Access fabric
- E
Configuring a shared Layer 3 handoff between the traditional campus and SD-Access fabric
Show answer and explanation
Correct answers: A, D, E
Explanation
To enable interoperability between a traditional campus network and an SD-Access fabric, the IT team must configure Border Nodes to bridge the two domains. LISP is used for endpoint mapping, ensuring proper communication, while a shared Layer 3 handoff ensures routing between the two networks. VXLAN encapsulation and Control Plane Nodes are specific to SD-Access operations and do not directly address interoperability with traditional networks.
- A. Correct.
Correct: Border Nodes are necessary to connect the SD-Access fabric to external networks, including traditional campus networks, enabling communication between the two domains.
- B. Incorrect.
Incorrect: Traditional campus networks typically do not use VXLAN encapsulation. VXLAN is a feature of the SD-Access fabric, not the legacy network.
- C. Incorrect.
Incorrect: Control Plane Nodes are part of the SD-Access architecture and are not directly involved in bridging traditional networks with the fabric. The border node handles this function.
- D. Correct.
Correct: LISP (Locator/ID Separation Protocol) is used in SD-Access to map endpoints between the traditional campus and the SD-Access fabric, ensuring seamless communication.
- E. Correct.
Correct: A shared Layer 3 handoff is required to enable routing between the traditional network and the SD-Access fabric, ensuring interoperability across the domains.
