Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Set the tablet to use a static IP address.

  Why it's wrong here

  Setting a tablet to use a static IP address ensures it always obtains the same network address, which is beneficial for consistent network identification but entirely unrelated to how the device transitions between different Wi-Fi access points. Wi-Fi roaming, or handoff, is a Layer 2 process involving the reassociation of the client device with a new access point, while IP address assignment occurs at Layer 3. Therefore, configuring a static IP address does not influence the efficiency or frequency of these Layer 2 roaming events.

• ✗

  Disable the tablet's Bluetooth radio.

  Why it's wrong here

  While Bluetooth operates in the 2.4 GHz band and can potentially interfere with Wi-Fi signals, leading to degraded performance or occasional drops, it is not the primary cause of frequent disconnects specifically during movement between coverage areas. Such symptoms typically indicate an issue with the device's ability to efficiently roam or hand off between access points. Disabling Bluetooth might mitigate some interference, but it does not address the core mechanism of client-side roaming decisions.

• ✗

  Configure the tablet to prefer the 2.4 GHz band over 5 GHz.

  Why it's wrong here

  Configuring a tablet to prefer the 2.4 GHz band over 5 GHz might offer better range and penetration through obstacles, potentially reducing the *number* of handoffs required by maintaining a connection to a more distant access point. However, this setting does not *improve* the actual handoff process itself. In fact, in congested 2.4 GHz environments, performance might suffer, and the device could cling to a weak 2.4 GHz signal longer, exacerbating roaming issues rather than resolving them.

• ✓

  Enable the 'Wi-Fi roaming' or 'aggressive handover' setting in the tablet's advanced Wi-Fi options.

  Why this is correct

  Enabling 'Wi-Fi roaming' or 'aggressive handover' in a tablet's advanced Wi-Fi settings directly influences the device's threshold for initiating a reassociation with a different access point. This setting prompts the client to proactively scan for and connect to a stronger AP sooner, even if the current signal is still marginally usable but weakening. By making the device more aggressive in switching, it minimizes the time spent on a weak signal, thereby preventing complete disconnects as the user moves between different access point coverage areas.
