Problem Solving.


1. Printer Problem You are attempting to print on a wireless printer from your laptop, but each time you click the Print button, you receive an error message that the printer is not connected. What are your next steps?

Check to see if the printer is plugged > Check to see if the printers WIFI is on > Check to see if the driver needs to be updated.

2. Projector Resolution Issue You are preparing for a meeting in your company’s conference room and have connected your laptop to the projector. When the projector displays the information from your laptop screen, the resolution drops significantly and not everything fits on the screen. What steps can you take to correct this problem?

Go to screen resolution on the desk top and change the settings to fit on the screen.

3. Fingerprints Not Recognized To increase security, your company now requires employees to sign in to their computer accounts using a fingerprint reader instead of entering a user name and password. This past weekend, you cut the finger you use to sign in, and your computer now does not recognize your fingerprint. As a result, you are unable to access your computer. What are your next steps?

You always what to add more than one fingerprint to the system. It is always a good thing to add two factor authentication and add a 3rd form in cases like this.

4. Access Denied Your Company uses security badges with embedded RFID tags to authenticate the rooms to which employees have access. This badge also grants employees access to the company’s parking lot. When arriving at work one morning, you wave your badge in front of the RFID reader, but the gate that allows access to the parking lot does not open. In addition, a red light blinks on the RFID reader. What are your next steps?

Contact the administrator of the card and either check the access of the card or get a replacement card.

5. Monitors Reversed You have two monitors on your desk at work: the monitor on the left is your primary monitor and displays the taskbar and the applications you currently are using, and you typically use the monitor on the right to display an email program. When you arrive at work and sign in to your Windows account, you realize that the monitor on the right is now the primary monitor. What might have happened?

The displays were physically swapped which threw off the display settings or the display settings were switched.
