- A
Disable the 'Adaptive battery' feature.
Why wrong: Incorrect. Adaptive battery limits background activity, but does not control Wi-Fi sleep behavior.
- B
Set the screen timeout to 'Never'.
Why wrong: Incorrect. This keeps the screen on, which drains battery and is not required for Wi-Fi connectivity.
- C
Configure 'Keep Wi-Fi on during sleep' to 'Always'.
Correct. This setting ensures the Wi-Fi radio stays active even when the device enters sleep mode.
- D
Enable 'Developer options' and set 'Stay awake'.
Why wrong: Incorrect. 'Stay awake' keeps the screen on while charging, not Wi-Fi connectivity during sleep.
Question 493 of 1,020
Android Tablet Keep Wi-Fi On During Sleep for POS
This 220-1201 practice question tests your understanding of mobile device application support. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Quick Answer
The correct answer is to configure 'Keep Wi-Fi on during sleep' to 'Always'. This setting ensures the Android tablet maintains its wireless connection to the point-of-sale network even when the screen is off, preventing transaction interruptions or lost data during idle periods. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of advanced Android power management and the specific requirements of a POS system, where constant connectivity is non-negotiable. A common trap is confusing this with screen timeout or Bluetooth settings, which do not control Wi-Fi behavior during sleep. Remember the mnemonic "Always On for Always Selling" to recall that a POS tablet must keep Wi-Fi active at all times.
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'.
Option C is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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
Incorrect. Adaptive battery limits background activity, but does not control Wi-Fi sleep behavior.
- ✗
Set the screen timeout to 'Never'.
Why it's wrong here
Incorrect. This keeps the screen on, which drains battery and is not required for Wi-Fi connectivity.
- ✓
Configure 'Keep Wi-Fi on during sleep' to 'Always'.
Why this is correct
Correct. This setting ensures the Wi-Fi radio stays active even when the device enters sleep mode.

- ✗
Enable 'Developer options' and set 'Stay awake'.
Why it's wrong here
Incorrect. 'Stay awake' keeps the screen on while charging, not Wi-Fi connectivity during sleep.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that 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.
Detailed technical explanation
How to think about this question
Android's Wi-Fi sleep policy is governed by a system-level wakelock mechanism. When 'Keep Wi-Fi on during sleep' is set to 'Always', the Wi-Fi subsystem holds a partial wakelock that prevents the radio from being powered down during suspend. This is distinct from the screen-on wakelock; the Wi-Fi radio can remain active even while the CPU enters a low-power state, allowing the device to receive network packets without keeping the screen lit. In a POS environment, this ensures the tablet can process payment authorizations and inventory updates without user interaction.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
