220-1101 Question 41
Single answerGlobal positioning system (GPS) servicesA field technician is setting up a company-issued tablet for a delivery driver who uses turn-by-turn navigation. The tablet can access the internet over cellular data, and map searches work, but the navigation app cannot determine the driver's live location when the driver is outside the warehouse. Other drivers using the same app on similar tablets are working normally. The technician confirms location services are turned on for the device. Which of the following should the technician check NEXT to restore real-time positioning?
- A
Whether the tablet's GPS feature is enabled and the app has permission to use precise location
- B
Whether NFC is enabled so the tablet can detect nearby navigation beacons
- C
Whether Bluetooth is paired to the vehicle so the tablet can calculate distance traveled
- D
Whether the screen rotation lock is disabled so the map can refresh orientation data
Show answer and explanation
Correct answer: A
Explanation
This scenario distinguishes between internet-based map functionality and GPS-based live positioning. A device can load maps and search destinations using cellular data or Wi-Fi, yet still fail to provide turn-by-turn navigation if GPS/location services are disabled, limited, or denied to the app. In practical A+ Core 1 troubleshooting, the best next step is to verify that the device's GPS/location function is enabled and that the specific app has permission to use precise location data. This aligns with standard mobile OS troubleshooting practices from vendors such as Apple and Google, both of which separate general connectivity from app-level location permissions. NFC, Bluetooth, and screen rotation are plausible distractors because they are common mobile features, but none of them provide the satellite/location-service function needed for real-time GPS navigation.
- A. Correct.
Correct. Internet connectivity can allow map tiles and address searches to work, but real-time navigation typically depends on the device's location hardware and permissions. On mobile devices, GPS services must be enabled, and the navigation app must be allowed to access precise location data. If either is disabled or restricted, the app may open and search maps but fail to determine the live position reliably.
- B. Incorrect.
Incorrect. NFC is used for very short-range communication such as tap-to-pair, payments, and badge interactions. It is not used for outdoor geolocation or turn-by-turn positioning. A candidate might choose this if they confuse wireless features on mobile devices, but NFC does not replace GPS services.
- C. Incorrect.
Incorrect. Bluetooth can connect the tablet to a car audio system or accessories, but it does not provide satellite-based positioning for navigation. Some accessories can share data over Bluetooth, but standard tablet navigation does not require a Bluetooth vehicle pairing to determine current location.
- D. Incorrect.
Incorrect. Screen rotation affects how content is displayed, not whether the device can obtain geolocation data. Orientation sensors such as the accelerometer and gyroscope may change map view behavior, but they do not provide the latitude/longitude fix required for live navigation.
