A customer has 20 stores located throughout a city. Each store has a single Cisco AP managed by a central WLC. The customer wants to gather analytics for users in each store. Which technique supports

Question

Options

• Aangle of arrival
• Bpresence
• Chyperlocation
• Dtrilateration

• B
  93% (28)
• C
  3% (1)
• D
  3% (1)

Explanation

Presence is the correct technique because it uses a single AP to detect Wi-Fi-enabled devices (smartphones, laptops, etc.) within its coverage area, allowing the customer to gather analytics such as foot traffic, dwell time, and visitor patterns - all without requiring multiple APs per location. This aligns perfectly with the scenario of one AP per store managed by a central WLC using Cisco's Connected Mobile Experiences (CMX) or DNA Spaces platform.

Angle of Arrival (A) and Hyperlocation (C) are wrong because they require specialized hardware (like Cisco's Hyperlocation APs with antenna arrays) and multiple APs to calculate precise device positioning - far beyond what a single standard AP can provide. Trilateration (D) is also incorrect because it requires a minimum of three APs to calculate a device's location by measuring signal distances, making it impossible with only one AP per store.

Memory Tip: Think of Presence as the "simplest" analytics tool - it only needs to sense that devices are present nearby, not pinpoint their exact location. Whenever you see "single AP + analytics," think Presence; whenever you see "precise location + multiple APs," think trilateration or hyperlocation.
