300-425 Question 155
Select 3An organization wants to implement a solution using Cisco's Presence services to track foot traffic and understand customer behavior in a retail store. Which of the following components are required to enable and deliver Presence services effectively within the Cisco Enterprise Wireless Network?
- A
Cisco Wireless LAN Controller (WLC) with Mobility Services Engine (MSE) integration
- B
Access points with location tracking capabilities
- C
Cisco Prime Infrastructure for analytics and reporting
- D
Client devices with pre-installed Cisco location tracking software
- E
A centralized DHCP server to allocate IP addresses to tracked devices
Show answer and explanation
Correct answers: A, B, C
Explanation
Cisco Presence services leverage wireless infrastructure to track and analyze the behavior of devices within a network. To achieve this, the Wireless LAN Controller (WLC) must integrate with the Mobility Services Engine (MSE) to process location data. Access points with location tracking capabilities are necessary for detecting devices, while Cisco Prime Infrastructure handles reporting and visualization of Presence data. Client devices do not require special software, as Presence services rely on passive signal detection, and DHCP is not directly relevant to this functionality.
- A. Correct.
The Cisco WLC is a core component for managing wireless networks, and integration with the Mobility Services Engine (MSE) is essential for Presence services to process and provide actionable location-based data.
- B. Correct.
Access points with location tracking capabilities are fundamental to detect and calculate the presence of devices based on signal strength and triangulation methods.
- C. Correct.
Cisco Prime Infrastructure can be used to manage and visualize Presence data, providing insights such as foot traffic, dwell time, and heatmaps.
- D. Incorrect.
Client devices do not require any pre-installed Cisco location tracking software for Presence services to work, as these services rely on wireless signals (e.g., Wi-Fi probe requests) emitted by standard client devices.
- E. Incorrect.
While a DHCP server is important for assigning IP addresses in a network, it is not a requirement for the specific operation of Presence services, as these services focus on tracking devices passively based on wireless signals.
