Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network architect is designing a wireless network for a large university campus with thousands of users and a high density of devices. The design requires centralized management, seamless roaming between access points (APs) across multiple buildings, and dynamic RF management to optimize coverage and capacity. Which wireless architecture is best suited for these requirements?
- AMesh AP architecture
- BController-based AP architecture
- CAutonomous AP architecture
- DCloud-managed AP architecture
Show answer & explanationAnswer & explanation
Correct answer: B. Controller-based AP architecture
A controller-based AP architecture provides centralized management, seamless roaming, and dynamic RF management by offloading intelligence from individual access points to a centralized Wireless LAN Controller (WLC). This is ideal for large, dense deployments like a university campus.
Why the other options are wrong
- A. Mesh APs are used for extending wireless coverage without Ethernet cabling, not primarily for centralized management or high-density roaming.
- C. Autonomous APs are standalone and lack centralized management and seamless roaming capabilities for large deployments.
- D. While offering centralized management, cloud-managed solutions might not always provide the same level of granular, on-premises RF control and integration as a dedicated WLC for very large, complex enterprise environments, though they are becoming more robust.
Controller-based Wireless Architecture
A wireless network design where lightweight access points (LAPs) are managed and controlled by a centralized Wireless LAN Controller (WLC).
- Provides centralized management and configuration.
- Enables seamless Layer 2 and Layer 3 roaming.
- Offers dynamic RF management for optimal coverage and capacity.
Memory trick: Wireless Choices: Independent, Centralized, or Cable-Free.
