You are the administrator of your company's network. Your network has five Windows 2000 server computers and 75 Windows 2000 Professional computers. The Windows 2000 Professional computers were installed by using a RIS image on one of the Windows 2000 Server computers. You need to upgrade several applications on the Windows 2000 Professional computers. The applications do not have built-in support for scripted installations.
You want to accomplish the following goals:
1. An unattended installation of the upgraded applications will be performed on the Windows 2000 Professional computers.
2. Existing user environments will be maintained on the Windows 2000 Professional computers.
3. The network name of each Windows 2000 Professional computer will be changed to match its asset tag.
4. The RIS image and the upgraded applications will be enabled as they are added to the network.
You take the following actions:
1. Install the RIS image on a Windows 2000 Professional computer named Computer1.
2. Install the upgraded applications on Computers1.
3. Change the network name of Computer1 to %DMI-SERIAL_NUM%.
4. Run RIPrep.exe on Computer1 to load the RIS image on to the RIS server.
5. Start all of the Windows 2000 Professional computers, and then load the RIS image from the RIS server.
Which result or results do these actions produce？ (Choose all that apply.)

Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be(56) by humans. "It is a burst of white noise that people say sounds like static (静电噪音) on the radio," she says. "its life-saving potential is(57)."

Withington studies how the brain(61) sounds at the university. She says that the(62) of a wide band of frequencies can be pinpointed (精确地确定) more easily than the source of a narrow band. Alarms(63) on the same concept have already been installed on emergency vehicles.
The alarms will also include rising or falling frequencies to(64) whether people should go up or down stairs. They were(65) with the aid of a large grant from British Nuclear Fuels.
