CompTIA 220-1101 Questions Answers

The correct answer is A. Install the latest graphics drivers.

The most likely cause of the external monitor not working after an operating system upgrade is that the graphics drivers are incompatible with the new version. Installing the latest graphics drivers from the manufacturer’s website or using Windows Update can resolve this issue. Replacing the monitor, restoring the operating system to the previous version, or reseating the external video adapter are not effective solutions for this problem.

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.

Two-factor authentication (2FA) is a method of verifying a user’s identity by requiring two pieces of evidence: something the user knows (such as a password) and something the user has (such as a device). A mobile authenticator application is a software program that runs on a smartphone or tablet and generates a one-time code or token that the user can enter along with their password to access a system. This adds an extra layer of security to prevent unauthorized access.
