Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2ArchitectureMedium
A network engineer is deploying a new Wi-Fi 6 (802.11ax) network for a high-density office building. The design requires centralized control, seamless roaming for users across floors, and efficient spectrum management. Which WLAN deployment model best fits these requirements?
- AAutonomous Access Point deployment
- BClient-based roaming deployment
- CMesh Access Point deployment
- DController-based Access Point deployment
Show answer & explanationAnswer & explanation
Correct answer: D. Controller-based Access Point deployment
A controller-based AP deployment provides centralized control, enables seamless roaming through coordinated APs, and offers advanced features like RF management and spectrum analysis, which are crucial for high-density Wi-Fi 6 environments.
Why the other options are wrong
- A. Autonomous APs operate independently, lacking centralized control, coordinated roaming, and efficient spectrum management required for a high-density environment.
- B. Client-based roaming relies solely on the client device to decide when and where to roam, which is inefficient and leads to poor performance in high-density, multi-AP environments without controller coordination.
- C. Mesh AP deployments are primarily designed for extending coverage where cabling is difficult, not for high-density office environments requiring centralized control and seamless client roaming.
Controller-based WLAN
A controller-based WLAN (also known as lightweight AP deployment) uses a centralized Wireless LAN Controller (WLC) to manage and coordinate multiple lightweight access points (APs).
- Centralized management and configuration.
- Seamless roaming and coordinated RF management.
- Scalable for large and high-density environments.
