300-430 Question 152
Single answerA retail store is implementing Cisco's presence services to analyze customer foot traffic and behavior within their premises. The IT team wants to use the wireless infrastructure to detect customers' devices even if they do not actively connect to the Wi-Fi network. Which feature or technology should be configured to enable this functionality?
- A
RSSI Thresholds
- B
Probe Request Analysis
- C
Fast Transition (802.11r)
- D
MAC Filtering
Show answer and explanation
Correct answer: B
Explanation
Probe Request Analysis is the correct choice because it allows Cisco's presence services to detect and track devices by analyzing probe requests sent by client devices searching for wireless networks. This is crucial for presence analytics as it enables detection of devices without requiring active connections to the Wi-Fi network.
- A. Incorrect.
RSSI Thresholds are used to determine the strength of a wireless signal but are not sufficient for detecting devices that are not actively connected to the Wi-Fi network.
- B. Correct.
Probe Request Analysis is a key feature of Cisco's presence services. It enables the wireless infrastructure to detect devices by analyzing the probe requests sent by clients, even if they are not connected to the network.
- C. Incorrect.
Fast Transition (802.11r) is a feature that facilitates seamless roaming between access points but is unrelated to device detection for presence services.
- D. Incorrect.
MAC Filtering is used for network access control but does not contribute to the detection of devices for presence analytics.
