What is the function of AC in wireless network? (Multiple choice)

Question

Options

• ACentralized management of APs
• BImplement roaming function
• CSend a beacon frame
• DWireless Intrusion Detection

• A
  74% (28)
• C
  26% (10)

Explanation

An AC (Access Controller), also called a Wireless LAN Controller, acts as the centralized brain of a managed wireless network. It handles centralized AP management (A) by pushing configurations, firmware, and policies to all APs from one point, and enables seamless roaming (B) by maintaining client session state and coordinating handoffs as devices move between APs. It also provides Wireless Intrusion Detection (D) by aggregating data from all managed APs to detect rogue devices and unauthorized access attempts across the entire network.

Option C is wrong because beacon frames are broadcast by the APs themselves - not the AC. Beacons announce the network's presence and are a radio-layer function handled at the AP edge, not by a centralized controller.

Memory tip: Think of AC as the controller - it Configures, Coordinates roaming, and Catches intruders. The AP is just the antenna doing radio work (like sending beacons); the AC never touches the air directly.
