350-401 Question #624: Real Exam Question with Answer & Explanation

Question

Which function does a fabric wireless LAN controller perform In a Cisco SD-Access deployment?

Options

• Amanages fabric-enabled APs and forwards client registration and roaming information to the
• Bcoordinates configuration of autonomous nonfabric access points within the fabric
• Cperforms the assurance engine role for both wired and wireless clients
• Dis dedicated to onboard clients in fabric-enabled and nonfabric-enabled APs within the fabric

Explanation

Fabric Wireless LAN Controller in Cisco SD-Access

In a Cisco SD-Access deployment, the Fabric WLC acts as a specialized controller that manages fabric-enabled APs and forwards critical client registration and roaming information to the control plane node (LISP Map Server), ensuring wireless clients are properly tracked and their mobility is handled within the fabric overlay - making Option A correct.

Why the distractors are wrong:

• Option B is incorrect because autonomous (nonfabric) APs operate outside the fabric and are not the primary concern of a Fabric WLC; the Fabric WLC specifically handles fabric-mode APs
• Option C is incorrect because the assurance engine role belongs to Cisco DNA Center's Assurance, not the WLC
• Option D is incorrect because the Fabric WLC is not dedicated solely to client onboarding; its primary role is AP management and forwarding registration/roaming data to the control plane

Memory Tip: Think of the Fabric WLC as a "wireless reporter" - it reports wireless client registration and roaming events to the control plane node, bridging the wireless world into the SD-Access fabric. If you remember "manage + report," you'll always land on Option A.
