Exam 350-401 topic 1 question 49 discussion

C. The control plane node’s database tracks all endpoints in the fabric site and associates the endpoints to fabric nodes, decoupling the endpoint IP address or MAC address from the location (closest router) in the network.

And this DB is known as Host Tracking Database (HTDB) - holds EID to RLOC bindings

Control plane is like a LISP server, which tracks and mapping endpoint

There is a way of remembering this: MTU is similar to MCU, 9x9 =81

From the OCG: A fabric control plane node is a LISP map server/resolver (MS/MR) with enhanced functions for SD-Access, such as fabric wireless and SGT mapping. It maintains a simple host tracking database to map EIDs to RLOCs.

C is correct The fabric control plane node is responsible for maintaining a comprehensive database of all endpoints and networks within the fabric. This database helps in facilitating endpoint identity and location services, allowing for efficient forwarding and policy enforcement within the SD-Access fabric.

C is correct

C is Correct

Ref: Cisco SD Access - Connecting to the Data Center, Firewall, WAN and More! “… Cisco SD Access Fabric Roles & Terminology … • Control-Plane Nodes – Map System that manages Endpoint to Device relationships …” A. It is responsible for policy application and network segmentation in the fabric. Wrong answer. B. It performs traffic encapsulation and security profiles enforcement in the fabric. Wrong answer. C. It holds a comprehensive database that tracks endpoints and networks in the fabric. Correct answer. D. It provides integration with legacy nonfabric-enabled environments. Wrong answer.

Fabric based on LISP Control Plane.
