Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2ArchitectureMedium
A network architect is designing a new Wi-Fi 6 (802.11ax) network for a high-density office environment. The design requires optimal performance for a large number of concurrent users, supporting both legacy and new client devices. Which WLAN deployment model provides centralized control, simplified management, and advanced RF optimization capabilities necessary for this scenario?
- AController-based AP deployment
- BAutonomous AP deployment
- CCloud-managed AP deployment
- DMesh AP deployment
Show answer & explanationAnswer & explanation
Correct answer: A. Controller-based AP deployment
A controller-based AP deployment centralizes control and management of multiple access points, enabling advanced features like centralized RF management, QoS enforcement, seamless roaming, and consistent policy application across the WLAN. This is crucial for optimizing performance in a high-density Wi-Fi 6 environment with diverse client types.
Why the other options are wrong
- B. Autonomous APs operate independently, lacking centralized control and advanced features for high-density environments.
- C. Cloud-managed AP deployments offer centralized management through a cloud portal, but the question specifically points to the underlying architecture for 'centralized control' and 'advanced RF optimization' which is characteristic of the controller-based model, whether on-prem or cloud-managed.
- D. Mesh AP deployments are for extending coverage without Ethernet cabling; they don't primarily address centralized control or high-density performance optimization.
Controller-based WLAN
A wireless network architecture where access points (APs) are managed and controlled by a central wireless LAN controller (WLC).
- Centralized management and configuration.
- Advanced RF management and optimization.
- Seamless roaming and QoS enforcement.
Memory trick: Autonomous APs are 'lone wolves', controllers are the 'pack leaders'.
