220-1102 Question 357
Single answerActivate/deactivateA technician is preparing a company-issued Windows 11 laptop for a traveling employee. The employee will be on a long flight and needs to conserve battery power while preventing accidental wireless connections during travel. The technician wants to quickly disable all radio transmitters without shutting down the laptop or removing any network adapters. Which action should the technician take?
- A
Enable Airplane mode in Windows Quick Settings
- B
Disable the Ethernet adapter in Network Connections
- C
Turn off Microsoft Defender Firewall for all network profiles
- D
Uninstall the Wi-Fi adapter from Device Manager
Show answer and explanation
Correct answer: A
Explanation
The best answer is to enable Airplane mode. In Windows 10 and Windows 11, Airplane mode is designed to deactivate wireless communications quickly, typically including Wi-Fi and Bluetooth, which is appropriate for travel and battery conservation. This is a temporary operational change rather than a permanent hardware or driver modification. From an A+ Core 2 perspective, this tests the ability to apply the correct OS feature for activating/deactivating device functionality in a real support scenario. Microsoft documentation for Windows Quick Settings and Airplane mode describes this feature as the supported method for turning wireless communications on or off quickly.
- A. Correct.
Correct. Enabling Airplane mode in Windows is the standard way to deactivate wireless radios such as Wi-Fi and Bluetooth at once while leaving the system powered on. This matches the goal of quickly disabling wireless communication for travel without removing hardware or making permanent configuration changes.
- B. Incorrect.
Incorrect. Disabling the Ethernet adapter affects only wired networking and does not address wireless radios. In this scenario, the concern is preventing wireless connections and reducing battery usage from radio transmitters during travel.
- C. Incorrect.
Incorrect. Microsoft Defender Firewall controls traffic filtering, not the activation state of wireless hardware. Turning it off would reduce security and would not disable Wi-Fi or Bluetooth radios.
- D. Incorrect.
Incorrect. Uninstalling the Wi-Fi adapter is unnecessary and disruptive. It removes the device driver configuration rather than simply deactivating the radio for temporary travel needs. This would create extra work and could require rescanning hardware or reinstalling drivers.
