Zorluk: OrtaNetwork Components Roles and Functions

An enterprise organization is expanding its campus wireless infrastructure by deploying lightweight access points (LAPs) across several buildings. To simplify administration, a network engineer installs a central device to handle radio frequency (RF) management, client authentication policies, and control-plane processing for all LAPs. Which network component performs these centralized control functions?

  1. Wireless LAN Controller (WLC)Cevap
  2. B
    Layer 2 Switch
  3. C
    Type 2 Hypervisor
  4. D
    Link Layer Discovery Protocol (LLDP) Agent

Cevap

The Wireless LAN Controller (WLC) is the network component responsible for centralized control-plane management, security policy enforcement, and RF coordination in a lightweight wireless architecture.
In a centralized Cisco wireless network using Split-MAC architecture, the Wireless LAN Controller (WLC) is dedicated to handling heavy control-plane operations, including RF channel and power management, client authentication, roaming assistance, and LAP configuration management.

Adım Adım Çözüm

1
Analyze the operational requirements described in the scenario.
The target component must centralize RF management, client authentication, and control-plane processing for lightweight access points.
Split-MAC architecture divides wireless responsibilities between access points and a central control entity.
2
Evaluate candidate network components against these requirements.
The Wireless LAN Controller (WLC) specifically terminates CAPWAP control tunnels from LAPs to deliver centralized management, channel assignment, power tuning, and security enforcement.
LAPs rely on the WLC for control-plane logic, whereas Layer 2 switches focus on frame switching, hypervisors manage virtual machines, and discovery protocols handle neighbor advertising.
