第3题：
You want to connect your Windows 2000 Professional computer to a new color laser printer. The printer is Plug and Play compliant. The printer is included on the current Hardware Compatibility List (HCL).
You are a member of the Sales organizational unit (OU). You want to share the printer with other users in the Sales Organizational Unit.
You plug the printer into the LPT port on the back of the computer. You then attempt to install the 32-bit application printer software that came with the printer. During the installation you receive an error message as shown in the exhibit.
What should you do before you share the printer to other users in the Sales OU?
A．Change the LPT port settings to enable legacy Plug and Play detection on your computer.
B．Change the LPT port setting to bidirectional in the BIOS on your computer. Then reinstall the printer software.
C．Connect the printer to another computer in the Sales Organizational Unit. Then install the device drivers for the printer.
D．Obtain and install WDM-compliant device drivers and printing software for the printer.
解析：Explanation: An error message with a reference to the print.dll file indicates a problem with the printer driver. The current print driver should be replaced with a WDM-compliant driver. WDM-compliant drivers and WDM-compliant printing software should be used to assure that the printers and the print devices work well in Windows 2000. The Windows Driver Model (WDM) provides a common model for device drivers across Windows 98 and Windows 2000 and would thus work in both Windows 98 and Windows 2000.
Incorrect answers:
A: The computer is a modern color laser printer, which is included in the Hardware Compatibility List (HCL). It is therefore not a legacy device. Therefore enabling legacy plug and play detection of the print port will not solve the problem in this scenario.
B: Bidirectional support enables communication between the physical print device and the Windows 2000 printer. This enables the print device to send status messages like "Low toner". Bidirectional support would not help with driver problems.
C: A printer driver is already installed, but the driver is not compatible with Windows 2000. You therefore need to install a WDM-compliant driver.

第7题：
Refer to the exhibit. A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands.Which two of these changes are necessary for SwitchA to meet the requirements? （）
A.Port security needs to be globally enabled.
B.Port security needs to be enabled on the interface.
C.Port security needs to be configured to shut down the interface in the event of a violation.
D.Port security needs to be configured to allow only one learned MAC address.
E.Port security interface counters need to be cleared before using the show command.
F.The port security configuration needs to be saved to NVRAM before it can become active.

You are the administrator of Ezonexam.com's network.
You want to connect your Windows 2000 Professional computer to a new TCP/IP based laser print device. The print device is Plug and Play compliant and is included on the current Hardware Compatibility List (HCL). When you attempt to create a new TCP/IP printer port you receive the following error message:
"Specified Port cannot be added. The port already exists."
You want to be able to use the new TCP/IP printer.
What should you do?
A．Modify the properties of the existing printer port to use the new print device.
B．Change the LPT port setting to bidirectional in the BIOS on your computer.
C．Change the LPT port setting to enable legacy Plug and Play detection on your computer.
D．Obtain and install the WDM-compliant device drivers and printing software for the printer.
解析：Explanation: The error message states that the new port cannot be added since it already exists. Thus all that is necessary to enable you to make use of the printer is to modify the properties of the existing port.
Incorrect answers:
B: Changing the port setting to bidirectional is not going to enable printing with the new print device.
The problem stems from the new port that cannot be added.
C: Since the print device is plug and play compliant and is included on the HCL, changing the port setting is not going to allow you to use the new TCP/IP printer because the problem stems from a port that cannot be added.
D: For hardware support Windows 2000 Professional includes the Win32 Driver Model (WDM). This provides a common model for device drivers across Windows 98 and Windows 2000. Drivers that are written to the WDM will work in both Windows 98 and Windows 2000. Windows 2000 uses a driver-signing process to make sure drivers have been certified to work correctly with the Windows Driver Model (WDM) in Windows 2000. However, the error message states that it is a port that cannot be added since it already exists. It is thus not a driver problem.
