Free CompTIA CloudNetX CNX-001 Actual Exam Questions - Question 4 Discussion
fans, the stadium owners want to implement a new wireless system. Currently, all tickets are
electronic and managed by the stadium mobile application. The new solution is required to allow
location tracking precision within 5ft (1.5m) of fans to deliver the following services:
Emergency/security assistance
Mobile food order
Event special effects
Raffle winner location displayed on the giant stadium screen
Which of the following technologies enables location tracking?
B imo, BLE is designed for indoor positioning and can easily meet the 5ft accuracy requirement. SSID and IoT are too broad or indirect, and NFC’s range is way too short for this use case.
B/C? BLE definitely fits the precision and range needed here, plus it supports continuous tracking without requiring direct user interaction. NFC’s range is too limited for anything beyond point-of-contact interactions, so it seems unlikely to cover all these use cases. IoT is more of an umbrella term for connected devices, not a specific tracking tech. SSID doesn’t provide location info. So between B and C, BLE makes more sense given the proximity accuracy and practical implementation in stadiums.
This one feels like BLE (B) for sure. NFC (C) is too short-range—basically touch-only—so it can't track location within 5ft across a stadium. SSID (A) just identifies Wi-Fi networks and won’t give precise location info either. IoT (D) is too broad; it’s about connecting devices but not specifically tracking people’s locations accurately. So, B fits best for the pinpoint tracking needed here.
B imo, BLE is designed for indoor positioning and can easily achieve that 5ft accuracy. NFC is way too close-range, and IoT is more about device connectivity, not precise tracking itself.
Maybe B makes the most sense since BLE beacons are commonly used for indoor positioning with good accuracy, unlike NFC which is way too short-range or just generic IoT that doesn’t guarantee precise location.
B/D? BLE handles the close-range part well, but IoT is what ties all devices and data together to actually use that location info across services like orders and security.
This is definitely about short-range wireless signals, so BLE fits perfectly for accurate tracking within a few feet. NFC is too limited in range, and IoT is more about the network of devices, not precise location itself. B
D imo, IoT covers a range of connected devices that can work together for location tracking, especially when combined with sensors and networks, not just BLE alone. It’s broader tech supporting the whole system.
Option B makes the most sense since BLE is designed for precise indoor positioning and can support real-time interactions like mobile orders or emergency alerts. NFC is way too short-range, basically just a few centimeters, so it won’t track fans over the whole stadium. SSID is just the network name and doesn’t give location data, and IoT is a broad term for connected devices, not a specific tracking tech. So BLE fits the bill for accuracy and practical use here.
I’m leaning towards B (BLE) here. Bluetooth Low Energy is known for good indoor positioning accuracy, often within a few meters, which fits the 5ft requirement better than the others. NFC is too short-range, SSID isn’t a tracking tech, and IoT is broad, not a specific location method. Anyone else think the same?
