A user on a company-managed Android device reports that a required business app is crashing immediately after launch. The app was working yesterday. The device is enrolled in the company's MDM. Which of the following is the most likely cause and the best first step?

Uninstall and reinstall the app from the MDM catalog.

Check if the app was updated overnight and if the update is incompatible with the device's Android version.

Clear the app's cache and data, then relaunch the app.

Factory reset the device to clear any corrupted system files.

An Android user reports that their phone charges very slowly and sometimes stops charging altogether. They are using a third-party charger and cable. The phone's battery health is reported as 'Good.' Which of the following is the most likely cause and the best first step?

The phone's software is corrupted; perform a factory reset.

The third-party charger or cable may not support the phone's fast-charging protocol; try the original charger and cable.

The phone's battery is failing despite showing 'Good' health; replace the battery.

The phone's charging port is damaged; replace the phone.

A user's iPhone cannot connect to a Bluetooth keyboard that was previously paired. The keyboard is on and discoverable. What should you try first?

Forget the keyboard in Bluetooth settings and pair it again.

Check the keyboard's battery level.

A user's Android phone can connect to Wi-Fi networks at home, but cannot connect to the office Wi-Fi. The office Wi-Fi requires a certificate for authentication. What should you check first?

Whether the phone's storage is full.

Whether the phone's Bluetooth is enabled.

Whether the certificate is installed and trusted on the phone.

Whether the phone's screen brightness is too low.

A company issues Android smartphones to employees. The IT department needs to ensure that only approved apps can be installed and that lost devices can be remotely wiped. Which solution should they implement?

Use a VPN on every device to secure internet traffic.

Deploy a Mobile Device Management (MDM) solution and enroll all company devices.

Set up a guest Wi-Fi network for the devices to isolate them from the corporate network.

Configure each device with a strong lock screen PIN and enable Find My Device.
