第1题：

You configure an HP Jet Direct print device as sown in the Network Diagram exhibit.

You want to create and share a printer at Srv2.sales.justtogs.com that is connected to the TCP/IP port of the print device. However, when you enter the IP address of the device, you receive the dialog box shown in thePrinterPortWizard exhibit.

PrinterPortWizard

What should you do?

A．Select Hewlett Packard JetDirect from the Standard drop-down list.

B．Select the Custom option button, click the Settings command button, and select the LPR protocol.

C．Change the IP address of the print device to 10.5.20.200.

D．Change the subnet mask of the print device to 255.0.0.0.

E．Change the default gateway address on Srv2.sales.justtogs.com to 10.5.20.100.


正确答案：C
解析：Explanation: The IP address of the printer, 10.4.20.100/16, is not on the same subnet as the default gateway, 10.5.20.100/16, or Srv1, 10.5.20.50/16. Changing the IP address to 10.5.20.200 would make communication with the printer possible.

Incorrect answers:
A: It is not necessary to specify the vendor type for the printer. The IP address of the printer is incorrect.

B: The LPR protocol is used in mixed environments, which includes UNIX machines.

D: The 16-bit subnet mask of the print device is correct therefore we do not need to change its subnet mask.
