220-1201 Practice Question: A technician is setting up a new Android tablet…
A technician is setting up a new Android tablet for a point-of-sale system. The tablet must stay on and connected to Wi-Fi at all times, even when the screen is off. Which setting should the technician adjust?
⚠ Common exam trap
Watch out — candidates often confuse 'screen timeout' with 'network connectivity' and select Option B, not realizing that keeping the screen on is unnecessary and wasteful, whereas the correct setting directly controls the Wi-Fi radio's behavior during sleep.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure 'Keep Wi-Fi on during sleep' to 'Always'.
The 'Keep Wi-Fi on during sleep' setting, when configured to 'Always', ensures the Wi-Fi radio remains active even when the screen is off. This is essential for a point-of-sale (POS) tablet that must maintain a constant network connection for transaction processing, regardless of the device's sleep state.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable the 'Adaptive battery' feature.
Why it's wrong here
Disabling the 'Adaptive battery' feature primarily affects how Android restricts background activity for individual applications based on usage patterns. While it can impact an app's ability to use network resources in the background, it does not directly control the fundamental power state of the Wi-Fi radio itself when the device enters a deep sleep mode. Therefore, it would not guarantee continuous Wi-Fi connectivity during sleep.
- ✗
Set the screen timeout to 'Never'.
Why it's wrong here
Setting the screen timeout to 'Never' keeps the device's display continuously active, preventing it from entering a low-power sleep state. While the Wi-Fi radio would remain active as long as the screen is on, this approach is highly inefficient and drains the battery rapidly. The objective is to maintain Wi-Fi connectivity during sleep, not to keep the screen illuminated indefinitely, which is a distinct power management function.
- ✓
Configure 'Keep Wi-Fi on during sleep' to 'Always'.
Why this is correct
This setting directly instructs the Android operating system to keep the Wi-Fi radio powered on and connected to the network even when the device's screen is off and it enters a sleep or idle state. By configuring 'Keep Wi-Fi on during sleep' to 'Always', background applications can continue to receive data, sync information, and deliver notifications without interruption. This is the precise and most power-efficient method to ensure continuous Wi-Fi connectivity during device sleep.
- ✗
Enable 'Developer options' and set 'Stay awake'.
Why it's wrong here
The 'Stay awake' option, found within Developer options, is specifically designed to prevent the device's screen from turning off *only when the device is actively charging*. This feature is primarily useful for debugging applications or for specific use cases where the screen needs to remain on while powered. It has no effect on the Wi-Fi radio's operational status or the device's ability to maintain network connectivity when it is unplugged and enters a sleep mode.
