300-430 Question 105
Select 3A large retail store wants to implement a location-based service to track customer movement and optimize store layouts. They plan to use their Cisco wireless infrastructure for location tracking. Which of the following configurations or technologies are necessary to implement accurate location services in this scenario?
- A
Deploy a minimum of three access points per area for triangulation purposes
- B
Enable RSSI threshold settings for client association
- C
Use Cisco CMX or DNA Spaces for location analytics and visualization
- D
Enable Fast Transition (802.11r) for seamless roaming
- E
Calibrate the wireless environment using location-specific site surveys
Show answer and explanation
Correct answers: A, C, E
Explanation
To implement accurate location services, it is essential to have a minimum of three access points in the area for triangulation, use tools like Cisco CMX or DNA Spaces for analytics, and calibrate the environment using site surveys. These steps ensure precise location tracking by leveraging the Cisco wireless infrastructure. Other settings like RSSI thresholds or roaming optimizations do not directly contribute to location accuracy.
- A. Correct.
Correct. Triangulation requires at least three access points to determine the location of a device with accuracy. This is a key principle for location-based services.
- B. Incorrect.
Incorrect. RSSI threshold settings are used to manage client association but do not directly contribute to location tracking or services.
- C. Correct.
Correct. Cisco CMX (Connected Mobile Experiences) or DNA Spaces is necessary for processing and visualizing location data, providing insights and analytics.
- D. Incorrect.
Incorrect. Fast Transition (802.11r) improves roaming performance for mobile clients, but it is not directly related to location tracking or services.
- E. Correct.
Correct. Calibrating the wireless environment with site surveys ensures that location tracking is accurate by accounting for environmental variables such as interference and attenuation.
