350-401 Question 49
Select 2An enterprise is deploying Cisco SD-Access to simplify network management and enhance security. During the design phase, the team needs to understand the roles of the control plane and data plane elements. Which of the following components are part of the control plane in a Cisco SD-Access architecture?
- A
LISP Map-Server/Map-Resolver
- B
Cisco DNA Center
- C
Fabric Edge Node
- D
Fabric Control Node
- E
Fabric Border Node
Show answer and explanation
Correct answers: A, D
Explanation
In Cisco SD-Access, the control plane is responsible for managing endpoint-to-location mappings and facilitating communication between fabric nodes. Key control plane elements include the LISP Map-Server/Map-Resolver, which handles mapping functions, and the Fabric Control Node, which manages host tracking and control plane signaling. Other elements like Fabric Edge and Border Nodes are part of the data plane as they focus on forwarding traffic.
- A. Correct.
LISP (Locator/ID Separation Protocol) Map-Server/Map-Resolver is part of the control plane in Cisco SD-Access. It handles endpoint-to-location mapping and is central to managing the control plane.
- B. Incorrect.
Cisco DNA Center is a management and automation platform for SD-Access but is not a control plane component. It provides policy, analytics, and orchestration functionalities.
- C. Incorrect.
Fabric Edge Node is a data plane component in Cisco SD-Access. It connects endpoints to the SD-Access fabric and forwards traffic.
- D. Correct.
Fabric Control Node is a control plane component that manages host tracking and LISP mappings. It plays a key role in ensuring the control plane operates effectively.
- E. Incorrect.
Fabric Border Node is a data plane component that connects the SD-Access fabric to external networks. It provides functions like traffic forwarding and segmentation enforcement but is not part of the control plane.
