Difficulty: EasyCisco Wireless Architectures and AP Modes

A network engineer needs to configure a dedicated Cisco lightweight Access Point (AP) to continuously scan all channels for wireless intrusion detection (WIDS) signatures and rogue access points without servicing client associations. Which operational AP mode should be configured on the access point?

  1. Monitor modeAnswer
  2. B
    Local mode
  3. C
    FlexConnect mode
  4. D
    Sniffer mode

Answer

Monitor mode
Monitor mode configures a Cisco lightweight Access Point as a dedicated security sensor. In this mode, the AP radios refrain from broadcasting SSIDs or serving client associations, and instead continuously cycle through all configured channels to detect rogue access points, intrusion attempts (WIDS), and radio frequency interference.

Step-by-Step Solution

1
Identify the primary operational requirement.
The access point must continuously scan all channels for security threats and rogue devices without serving client connections.
The requirement specifies a dedicated monitoring role.
2
Evaluate Cisco lightweight AP modes against the requirement.
Monitor mode disables client association functions and enables continuous channel scanning for WIDS and rogue detection.
Local and FlexConnect modes service client connections, whereas Sniffer mode focuses on single-channel packet capturing.
