220-1201 Practice Question: A user's smartphone intermittently drops Wi-Fi…
A user's smartphone intermittently drops Wi-Fi connection when the device is moved from one room to another. The home uses a single Wi-Fi router. The technician suspects the issue is related to the device's power management. Which setting should be adjusted to maintain a stable connection?
⚠ Common exam trap
The 220-1201 exam often tests the distinction between power management settings (like Wi-Fi power saving mode) and connectivity settings (like band selection or sleep behavior), trapping candidates who confuse range-related fixes with power-saving adjustments.
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
✓
Disable 'Wi-Fi power saving mode' in the advanced Wi-Fi settings.
Disabling 'Wi-Fi power saving mode' prevents the device from reducing radio power or entering low-power states when moving between rooms, which can cause intermittent signal drops. This setting directly addresses the power management behavior that leads to unstable connections during transitions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable 'Wi-Fi calling' to offload calls to cellular.
Why it's wrong here
Enabling 'Wi-Fi calling' routes voice calls and SMS messages over a Wi-Fi network instead of the cellular network. While this feature can improve call quality in areas with poor cellular reception, it is specifically designed for voice communication. It has no direct impact on the stability or intermittent dropping of the smartphone's general data connection when connected to Wi-Fi.
- ✗
Set the device to 'Keep Wi-Fi on during sleep' to 'Always'.
Why it's wrong here
The 'Keep Wi-Fi on during sleep' setting primarily addresses scenarios where the Wi-Fi connection drops when the device's screen is off and it enters a low-power state. The problem described, intermittent drops, implies the issue occurs during active usage or movement, not specifically when the device is idle or sleeping. Therefore, modifying this setting would not resolve a connectivity problem experienced while the smartphone is actively in use.
- ✓
Disable 'Wi-Fi power saving mode' in the advanced Wi-Fi settings.
Why this is correct
Wi-Fi power saving mode, often found in advanced Wi-Fi settings, reduces the power consumption of the device's Wi-Fi radio to conserve battery. This can lead to the radio operating at a lower signal strength or scanning less frequently, making it more susceptible to intermittent disconnections, especially when the signal is marginal or the device is moving. Disabling this feature ensures the Wi-Fi radio operates at full power, maintaining a more robust and stable connection.
- ✗
Change the Wi-Fi frequency band from 5 GHz to 2.4 GHz.
Why it's wrong here
Changing the Wi-Fi frequency band from 5 GHz to 2.4 GHz primarily affects range and penetration, with 2.4 GHz offering broader coverage but often more interference and lower theoretical speeds. While a band change might be relevant if the issue were consistently poor signal or range, intermittent drops suggest a different underlying problem. This action does not address potential power management or radio stability issues that cause sporadic disconnections rather than consistent signal weakness.
