350-401 Question 45
Single answerAn organization is deploying Cisco SD-Access to simplify network operations and enhance security. The network engineer explains that the solution uses a Fabric Control Plane to manage endpoint-to-endpoint communication. Which component of the Cisco SD-Access architecture facilitates this function?
- A
LISP (Locator/ID Separation Protocol)
- B
VXLAN (Virtual Extensible LAN)
- C
ISE (Identity Services Engine)
- D
DNA Center
Show answer and explanation
Correct answer: A
Explanation
The Cisco SD-Access solution uses LISP (Locator/ID Separation Protocol) as the Fabric Control Plane technology. LISP maps endpoint identities to their locations in the network, allowing for seamless and efficient communication between endpoints. This is a critical function of the SD-Access architecture, enabling the separation of identity and location for simplified operations and enhanced scalability.
- A. Correct.
LISP (Locator/ID Separation Protocol) is the technology used in the Fabric Control Plane to map endpoint identities to their locations, enabling efficient endpoint-to-endpoint communication in the Cisco SD-Access solution.
- B. Incorrect.
VXLAN (Virtual Extensible LAN) is used in the Cisco SD-Access Data Plane for encapsulating traffic and enabling Layer 2 stretching across the fabric, but it does not manage the Control Plane.
- C. Incorrect.
ISE (Identity Services Engine) is used for user and device authentication and policy enforcement in Cisco SD-Access, but it is not responsible for managing the Fabric Control Plane.
- D. Incorrect.
DNA Center is the centralized management tool that automates and orchestrates Cisco SD-Access deployments, but it does not directly manage the Fabric Control Plane.
