CCNP Infrastructure Practice Question
A network engineer is implementing Cisco SD-Access and needs to configure the fabric to support both wired and wireless clients. Which two components are required to enable wireless integration in a Cisco SD-Access fabric? (Choose two.)
⚠ Common exam trap
The trap here is assuming that any fabric node (like Edge or Border) is sufficient for wireless integration, when in fact specific wireless components (Fabric WLC and fabric-enabled APs) are required.

Correct answer & explanation
✓
Fabric Wireless Controller (WLC)
To integrate wireless clients into a Cisco SD-Access fabric, you need a Fabric Wireless Controller (WLC) to manage the wireless infrastructure and a fabric-enabled Access Point to connect wireless clients to the fabric. The Fabric WLC communicates with the fabric control plane to register client locations, and the APs encapsulate traffic in VXLAN. Other components like Fabric Edge, Border, and Control Plane nodes are part of the fabric but are not specific to enabling wireless integration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Fabric Border Node
Why it's wrong here
Fabric Border Nodes connect the SD-Access fabric to external networks, such as the data center or WAN. They are not specific to wireless integration; they handle traffic exiting the fabric for both wired and wireless clients. While they are essential for external connectivity, they do not enable wireless clients to join the fabric. The wireless-specific components are the Fabric WLC and the fabric-enabled access points.
- ✓
Fabric Wireless Controller (WLC)
Why this is correct
The Fabric Wireless Controller (WLC) is essential for integrating wireless access points into the SD-Access fabric. It manages the wireless infrastructure and communicates with the fabric control plane to register wireless clients and their locations. The Fabric WLC uses VXLAN to tunnel client traffic to the fabric edge nodes. Without it, wireless clients cannot be part of the fabric's unified policy and segmentation. Thus, it is a required component for wireless integration.
- ✓
Fabric-enabled Access Point
Why this is correct
Fabric-enabled Access Points (APs) are required for wireless integration in SD-Access. These APs are configured to operate in fabric mode, where they register with the Fabric WLC and encapsulate client traffic in VXLAN to the fabric edge. They also support the fabric's security and segmentation policies. Without fabric-enabled APs, wireless clients cannot be integrated into the SD-Access fabric. Therefore, they are a necessary component.
- ✗
Fabric Edge Node
Why it's wrong here
Fabric Edge Nodes are required for wired clients and also for wireless clients, but they are not specific to wireless integration. They provide the anycast gateway and enforce policies for both wired and wireless traffic. However, the question asks for components required to enable wireless integration. While Edge Nodes are part of the overall fabric, they are not the distinguishing component for wireless. The specific wireless components are the Fabric WLC and the fabric-enabled APs.
- ✗
Fabric Control Plane Node
Why it's wrong here
The Fabric Control Plane Node is responsible for maintaining the location database of all endpoints, both wired and wireless. It is a critical component of the overall SD-Access architecture, but it is not specific to wireless integration. The control plane node works with the Fabric WLC to track wireless clients, but its primary function is not wireless-specific. The question asks for components required to enable wireless integration, which are the Fabric WLC and fabric-enabled APs.
