Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureHard
A network architect is designing a wireless network for a large university campus with thousands of users. The design requires centralized management, seamless roaming across a vast area, and robust security features at scale. Which wireless network architecture is best suited for this scenario?
- AController-based architecture
- BCloud-managed AP architecture
- CMesh network architecture
- DAutonomous AP architecture
Show answer & explanationAnswer & explanation
Correct answer: A. Controller-based architecture
A controller-based wireless architecture is ideal for large-scale deployments like a university campus. It provides centralized management of thousands of access points, enables seamless Layer 2 and Layer 3 roaming, and offers robust security features that can be consistently applied across the entire network.
Why the other options are wrong
- B. While cloud-managed APs offer centralized management, the question implies a traditional on-premise controller for 'robust security features at scale' and 'seamless roaming' which is a hallmark of WLCs. Cloud-managed solutions typically simplify deployment but might not offer the same deep integration and control as an on-premise WLC for complex enterprise needs (though modern cloud solutions are closing this gap, controller-based is the most classic and direct fit for ENCOR context).
- C. Mesh networks are typically used for extending coverage where cabling is difficult, not primarily for centralized management and seamless roaming across a campus.
- D. Autonomous APs are managed individually and do not scale well for thousands of users or provide seamless roaming.
Controller-based Wireless Architecture
A wireless network design where Access Points (APs) are centrally managed by a Wireless LAN Controller (WLC), enabling centralized control, seamless roaming, and advanced security features.
- Centralized management of APs.
- Facilitates seamless Layer 2 and Layer 3 roaming.
- Scalable for large deployments.
- Enhanced security and policy enforcement.
