350-401 Question 53
Single answerAn enterprise network consists of a traditional campus network that needs to interoperate with a newly deployed Cisco SD-Access fabric. The goal is to allow seamless communication between traditional VLANs on the campus network and the SD-Access fabric while maintaining policy enforcement. Which method should be implemented to achieve this integration?
- A
Use an SD-Access Border Node to connect the traditional network to the fabric.
- B
Enable Fabric Edge nodes to directly communicate with VLANs in the traditional network.
- C
Deploy a Layer 2 trunk between the traditional network and the SD-Access fabric.
- D
Configure a Fusion Router for communication between the traditional network and the SD-Access fabric.
Show answer and explanation
Correct answer: A
Explanation
To enable interoperation between a traditional campus network and an SD-Access fabric, an SD-Access Border Node must be implemented. The Border Node acts as the gateway between the SD-Access fabric and external networks, allowing seamless communication and policy enforcement. Other options, such as Fabric Edge nodes or Layer 2 trunks, do not provide the appropriate functionality or scalability for this scenario.
- A. Correct.
Correct: An SD-Access Border Node is responsible for connecting the SD-Access fabric to external networks, such as a traditional campus network, while ensuring policy enforcement and seamless communication.
- B. Incorrect.
Incorrect: Fabric Edge nodes are used to connect endpoints to the SD-Access fabric, but they are not designed to directly interoperate with traditional VLANs from a legacy network.
- C. Incorrect.
Incorrect: A Layer 2 trunk does not provide the necessary policy enforcement or scalability required for integration between SD-Access and a traditional campus network.
- D. Incorrect.
Incorrect: A Fusion Router is used for inter-fabric communication or integration, but it is not the primary method to connect a traditional network to an SD-Access fabric.
