Objective 4.5 Questions

1.	Which of the following type of port is represented in Device Manager by the label Printer Port (LPT1)? A parallel port A serial port A FireWire port A USB port
2.	A customer using Windows XP Home Edition calls and complains that he has connected an external 56-Kbps modem to his computer using a serial cable. However, the download speeds for the modem seem very slow to the user. What should you check first? You should download the latest firmware from the modem manufacturer’s website and update the modem. You should tell the user that external modems are limited by the speed of the serial port, which is far less than 56 Kbps. You should configure a higher speed using the Properties dialog box for the network connection configured for the modem. You should use the modem’s Properties dialog box in Device Manager to change the port speed for the serial port.
3.	One of your users has just purchased a used printer with a parallel port connection and asks you to set it up. You connect the printer to the parallel port and install the software that came with the printer but cannot get Windows to recognize the printer. You check Device Manager, and you do not see a printer port listed in the Ports (COM & LPT) category. What is the likely problem? The parallel port is disabled in the computer’s BIOS. The proper drivers are not installed for the port. The parallel cable you are using is bad. You should run Windows Update to locate more recent software for the printer.
4.	Which of the following lists represents the correct order of each port type’s maximum rated speed from slowest to fastest? Serial, FireWire, USB 1.1, USB 2.0 Serial, USB 1.1, USB 2.0, FireWire USB 1.1, Serial, USB 2.0, FireWire USB 1.1, USB 2.0, Serial, FireWire
5.	A customer calls and tells you that he recently installed a new driver for his scanner. Following the installation, his scanner stopped working. The customer has performed no other actions. What is the best action to take? Use the Driver tab of the scanner’s Properties dialog box in Device Manager to roll back the driver to the previous version. Use the Add Or Remove Programs tool in Control Panel to uninstall the updated driver. Disconnect the scanner and then reconnect it. Disconnect the scanner, uninstall all software related to the scanner, and then reinstall the scanner using the original software.
6.	One of your customers uses a notebook computer at home and occasionally takes it with her when she travels. At home, she has a printer connected to the computer’s parallel port. When she travels, she disconnects the printer. However, when she starts the computer, she gets an error that the printer cannot be found. She wants to be able to disable the printer when she travels and re-enable it when she returns home. What should you tell the customer to do? Enter the setup screen for the computer’s BIOS and disable the parallel port before she leaves home and enable the port when she returns. Use the Properties dialog box for the printer in Device Manager to disable the printer port before she leaves home and to enable the printer port when she returns. Use the Properties dialog box for the printer in Device Manager to disable the printer before she leaves home and to enable the printer when she returns. Use the msconfig.exe utility to disable the printer at Windows startup before she leaves home and to enable the printer when she returns.

Answers

1.	Correct Answers: A Correct Printer Port (LPT1) is a parallel port. Incorrect Printer Port (LPT1) represents a parallel port, not a serial port. Serial ports are represented in Device Manager with the label Communications Port (COMx), where x is the number of the port. Incorrect Printer Port (LPT1) represents a parallel port, not a FireWire port. FireWire ports are represented in Device Manager by the label FireWire Controllers or IEEE 1394 Bus Host Controllers. Incorrect Printer Port (LPT1) represents a parallel port, not a USB port. USB ports are grouped in a common category in Device Manager labeled Universal Serial Bus Controllers.
2.	Correct Answers: D Incorrect External modems are not typically upgradeable in this manner. This method does not solve the problem, anyway. Incorrect This is not true; serial ports are capable of speeds up to 128 Kbps. Incorrect You must use Device Manager to change the port speed. Correct You can use the modem’s Properties dialog box to change the supported speed of the port to match or exceed the speed of the modem.
3.	Correct Answers: A Correct If you do not see a port listed in the Ports (COM & LPT) category the chances are high that the port is disabled in the computer’s BIOS. Incorrect Windows XP includes built-in drivers for serial and parallel ports. Were a port available, it would be configured automatically. Incorrect A bad parallel cable would not cause the printer port to not be listed in Device Manager. Incorrect Windows Update does not provide third-party software other than certain hardware drivers. This method does not solve the problem, anyway.
4.	Correct Answers: B Incorrect This is not the correct order. Correct This is the correct order. Serial ports have a maximum speed of 128 Kbps. USB 1.1 has a maximum speed of 12 Mbps. USB 2.0 has a maximum speed of 480 Mbps. FireWire has a maximum speed of 800 Mbps. Incorrect This is not the correct order. Incorrect This is not the correct order.
5.	Correct Answers: A Correct Windows XP allows you to roll a driver back to a previous version if a new driver causes problems. Incorrect The Add Or Remove Programs tool in Control Panel does not usually display hardware drivers. Incorrect This does not solve a problem caused by a new driver. Incorrect Although this would probably achieve the desired result, it is an overly burdensome solution.
6.	Correct Answers: C Incorrect If the customer disables the port in the BIOS, she will still get an error message when the printer is not found. Incorrect If the customer disables the printer port, she will still get an error message when the printer is not found. Correct You can use Device Manager to enable and disable individual hardware devices. Incorrect You cannot use msconfig.exe to control the starting of hardware devices.
