300-430 Question 141
Select 2A network administrator is tasked with determining the location of a rogue access point within a corporate network. The wireless infrastructure comprises Cisco Catalyst 9800 Series Wireless Controllers and Cisco DNA Center. Which of the following methods should the administrator use to detect and locate the rogue access point?
- A
Use Cisco DNA Center's Rogue Management feature to visualize the rogue AP's location on a heatmap.
- B
Perform a manual site survey with a spectrum analyzer to identify the rogue AP's signal strength.
- C
Enable Radio Resource Management (RRM) on the wireless controller to automatically block the rogue AP.
- D
Leverage the Client View on Cisco DNA Center to analyze associated rogue clients for triangulation.
- E
Use the Rogue Detection feature on the wireless controller to identify and locate the rogue AP.
Show answer and explanation
Correct answers: A, E
Explanation
Cisco DNA Center's Rogue Management feature and the Rogue Detection feature on Cisco wireless controllers are specifically designed to detect and locate rogue APs within a network. These tools leverage the capabilities of the Cisco wireless infrastructure, such as triangulation, to provide accurate and efficient rogue AP detection. Manual methods or features not designed for rogue AP detection, such as RRM or Client View, are less effective or irrelevant for this purpose.
- A. Correct.
Cisco DNA Center's Rogue Management feature provides visualization tools, including heatmaps, to detect and locate rogue APs effectively.
- B. Incorrect.
A manual site survey can identify rogue AP signals, but it is time-consuming and lacks the precision provided by automated tools like Cisco DNA Center or wireless controllers.
- C. Incorrect.
RRM is designed for channel and power optimization in managed networks, not for rogue AP detection or blocking.
- D. Incorrect.
The Client View in Cisco DNA Center is used to analyze client behavior and connectivity but is not designed for rogue AP detection or triangulation.
- E. Correct.
The wireless controller's Rogue Detection feature uses techniques like triangulation from multiple APs to pinpoint the rogue AP's location.
