Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Palm detection is disabled or not functioning properly in the touchpad settings.. Palm detection is designed to prevent accidental cursor movement when the user's palms rest on the touchpad during typing. When this feature is disabled or not working, the touchpad interprets palm contact as valid input, causing erratic cursor jumps. Adjusting or enabling palm detection in the touchpad settings directly addresses the reported behavior.

Answer

The touchpad is configured for a left-handed user.

Answer

The touchpad sensitivity is set too high, causing accidental input from palm contact.

Answer

The touchpad driver needs to be rolled back to a previous version.

Question 2

A field technician is configuring a ruggedized Windows tablet for a client. The client requires that the tablet automatically connect to a specific Bluetooth headset whenever it is turned on and in range, without user intervention. Which of the following should the technician do to meet this requirement?

Accepted Answer

Pair the headset and enable the option to automatically connect when in range.. To automatically connect a Bluetooth headset when in range, the device must first be paired, and then the auto-connect option must be enabled in the Bluetooth settings. This ensures the tablet initiates the connection without user interaction. Other settings, such as default audio device or tethering, do not trigger automatic connections and are therefore incorrect.

Answer

Configure the headset to be discoverable at all times.

Answer

Enable Bluetooth tethering on the tablet.

Answer

Set the headset as the default audio device in the sound settings.

Question 3

A user with an Android smartphone reports that the device's battery drains unusually fast, even when the screen is off. The technician suspects that one or more apps are keeping the device awake. Which of the following actions should the technician take to identify the cause? (Choose two.)

Accepted Answer

Review the list of apps with permission to run in the background.. To identify an app causing battery drain, the technician should examine battery usage statistics and review background app permissions. These built-in Android features provide data on which apps are consuming power and allow the technician to restrict background activity. Task killers, disabling radios, or factory resets are not diagnostic and may not address the root cause.

Answer

Use a third-party task killer to automatically kill background apps.

Answer

Perform a factory reset of the device.

Answer

Disable Bluetooth and GPS to save battery.

Question 4

A user wants to use their smartphone to make contactless payments at retail stores. The phone supports NFC. Which of the following must be configured on the phone to enable this functionality?

Accepted Answer

A mobile payment service with a linked credit card.. NFC contactless payments require a mobile payment service, such as Google Wallet or Apple Pay, with a linked payment card. The service handles tokenization and communicates with the terminal via NFC. Bluetooth pairing, USB OTG, or QR scanner apps are not involved in this process. Thus, configuring a payment service is the essential step.

Answer

Install a QR code scanner app.

Answer

Bluetooth pairing with the payment terminal.

Answer

Enable USB OTG on the phone.
