A manufacturing company uses a specialized printer which connects to a Windows computer over a USB connection. Which of the following would be the BEST way to allow all Windows devices in the company to send print jobs to this printer?

• Connect using AirPrint

• Configure Windows Printer Sharing

• Use Print to File and copy the file to the printer

• Copy the print jobs to a USB drive

Answer explanation

The Answer: B. Configure Windows Printer Sharing

Windows Printer Sharing allows the Windows computer to act as a print server. All devices on the network can view the printer and send print jobs to the printer using the Printer Sharing feature.

The incorrect answers:

A. Connect using AirPrint

AirPrint is a technology used by Apple iOS to print to compatible network printers. AirPrint would not be the default method for printing from Windows devices to a Windows-connected printer.

C.   Use Print to File and copy the file to the printer

Using Print to File would create a local print file, but that file would need to be manually copied from the Windows computer to the printer. This process would be time consuming and would interrupt the local Windows user each time a print job was needed.

D.   Copy the print jobs to a USB drive

Similar to the Print to File option, putting the print jobs on a USB drive would require a manual process by the user connected to the printer. This can be easily avoided by enabling Printer Sharing and having the users submit the print jobs themselves.

A company has acquired computers that were previously part of a third-party lease. All of the computers prompt for a password when powering on the system before the operating system will load, but the password was not included with the computers. Which of the following would be the BEST way to resolve this issue?

• Replace the primary storage drive

• Boot from the Windows installation media

• Reset the BIOS using jumpers on the motherboard

• Disconnect the power cable for ten minutes

Answer explanation

The Answer: C. Reset the BIOS using jumpers on the motherboard The BIOS (Basic Input Output System) of a computer can often be assigned configuration or management passwords to prevent any changes to the BIOS settings. The BIOS also supports a boot or user password, and the system will not boot until the correct password is entered. This password can often be reset by shorting a jumper on the motherboard  and restarting.

The incorrect answers:

A.  Replace the primary storage drive

The BIOS password configuration isn't saved on a storage drive, so replacing the drive will not bypass the password.

B.  Boot from the Windows installation media

The boot password applies to all boot media, including any attempts to boot from DVD-ROM or USB drive.

D. Disconnect the power cable for ten minutes

The password and BIOS configuration is saved on the motherboard in non-volatile memory. Disconnecting the power will not reset the password or change the BIOS configuration.

A user has complained that a laptop will not charge the battery past 25% percent, and the laptop only operates for fifteen minutes when on battery power. The battery and the AC adapter have already been replaced. Which of the following components would be the MOST likely cause of this issue?

• Motherboard

• Backlight inverter

• 802.11 adapter

• CPU

Answer explanation

The Answer: A. Motherboard

The motherboard on a laptop usually contains all of the major subsystems, including the CPU (Central Processing Unit), memory, video, and power. If the laptop will not charge a battery or power the system, then the entire motherboard will need to be replaced.

The incorrect answers:

B. Backlight inverter

A backlight inverter is used on CCFL (Cold Cathode Fluorescent Lamp) displays to convert the internal laptop DC (Direct Current) power source to AC (Alternating Current). The backlight inverter is not part of the laptop's battery charging system.

C.   802.11 adapter

An 802.11 wireless adapter is usually connected directly to the motherboard, and is responsible for managing the wireless communication to the 802.11 network. A faulty 802.11 adapter would not commonly prevent the laptop battery from charging.

D.   CPU

The CPU is the primary processor for the laptop. A CPU does not manage the charging process for a laptop battery, and the charging subsystem can operate even when the laptop is completely powered down.

• Bluetooth

• Hotspot

• MAN

• NFC

Answer explanation

The Answer: B. Hotspot

Configuring a mobile phone as a hotspot allows one or more people to use the phone's Internet connection over Wi-Fi. If Internet isn't currently available from another 802.11 wireless network, then using the hotspot feature can provide an option for Internet access.

The incorrect answers:

A. Bluetooth

Bluetooth is a useful personal area network (PAN), but it won't provide any Internet access by itself.

C. MAN

A MAN (Metropolitan Area Network) is a network connecting multiple sites in a single city or metropolitan area. A MAN is usually installed by a network service provider and would not commonly be available to a remote site that's currently under construction.

D. NFC

NFC (Near Field Communication) is a short-range networking method designed to send small amounts of data at a time. It's common to use NFC with a smartphone or smart watch to pay for items in a store, but NFC can't be used to gain Internet access through a smartphone.

Which of the following would be the MOST likely reason the finishing function of a printer would punch two holes in a page instead of three?

• The incorrect paper tray is selected

• The print driver is not configured properly

• The printer is low on toner

• The connection between the computer and the printer is faulty

Answer explanation

The Answer: B. The print driver is not configured properly

Some large printers include finishing features for adding staples or holes to the final document. If the print driver is not set correctly, these options may be placed in the incorrect location or not used at all. The printer driver may need to be reconfigured or updated to support these finishing features.

The incorrect answers:

A. The incorrect paper tray is selected

Many printers include different paper trays and often use different  types of paper in each tray. The paper punch occurs after the output is printed, so the choice of paper tray should not cause any issues with the finishing process.

C.  The printer is low on toner

If the printer toner is low, the printer will usually show a "low toner" error and the output will print normally. Because the toner is low, the output will usually be a bit more faded than normal. A low toner message would not change the printer's hole punching process.

D.  The connection between the computer and the printer is faulty. A faulty connection between the computer and printer will usually result in no output or an interruption to the output process. This will not commonly result in problems with the finishing process.
