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. The design requires centralized management of Access Points (APs), seamless roaming for clients across buildings, and consistent application of security policies. Which wireless architecture best meets these requirements?
- AMesh wireless network
- BAd-hoc wireless network
- CController-based architecture
- DAutonomous AP architecture
Show answer & explanationAnswer & explanation
Correct answer: C. Controller-based architecture
A controller-based wireless architecture centralizes the management, configuration, and control functions for multiple Access Points. This design is ideal for large deployments like a university campus, providing seamless roaming, consistent policies, and simplified administration.
Why the other options are wrong
- A. Mesh networks extend coverage wirelessly between APs but don't inherently provide the centralized management and advanced roaming capabilities of a controller-based system.
- B. Ad-hoc networks are peer-to-peer and lack centralized control, security, and scalability for a large campus.
- D. Autonomous APs are individually managed, making them unsuitable for large-scale deployments requiring centralized control and seamless roaming.
Controller-based Wireless Architecture
A wireless network design where a central controller manages and controls multiple lightweight Access Points.
- Centralized management and configuration of all APs.
- Enables seamless client roaming across different APs.
- Simplifies policy enforcement and security across the network.
Memory trick: A controller is the conductor of the wireless orchestra.
