Correct Answer:

The next troubleshooting step that the technician should attempt is to restart
the smartphone. Restarting the smartphone can help resolve many common issues, such as battery drain, network utilization, app crashes, or performance slowdowns. Restarting the smartphone can do the following:
✑ Clear the memory and cache of the smartphone, which can free up space and speed up the device.
✑ Close any background apps or processes that may be consuming battery or network resources, such as syncing, updating, or streaming.
✑ Reset the network settings and connections of the smartphone, which can improve the signal strength and quality.
✑ Refresh the operating system and the user interface of the smartphone, which can fix any glitches or errors.
To restart the smartphone, the user can follow these steps:
✑ Press and hold the power button of the smartphone until a menu appears on the screen.
✑ Tap the option that says Restart, Reboot, or Power off and on.
✑ Wait for the smartphone to turn off and then turn on again.
✑ Enter the PIN, password, or pattern to unlock the smartphone.
✑ Check the battery level and the network utilization of the smartphone.
If restarting the smartphone does not solve the problem, the technician may need to try other troubleshooting steps, such as updating the mobile OS, disabling Bluetooth, or connecting the smartphone to a Wi-Fi network. However, restarting the smartphone is usually the first and simplest step to try.

A crimper is a tool that is used to attach connectors to network cables, such as RJ-45 or RJ-11. A technician might need a crimper to create a longer cable for the router access point or to replace a damaged connector.
A Wi-Fi analyzer is a software or hardware tool that can scan and measure the wireless signal strength, interference, channel usage, and security of a Wi-Fi network. A technician might need a Wi-Fi analyzer to find the optimal location and configuration for the router access point to improve the signal coverage for the SOHO client.
