参考答案
正确答案：B
解析：Explanation: Performing an unattended installation from a distribution server will work since the upgrade must be done in non-business hours.
An answer file provides the generic answers to setup questions. This is typically a file with a .txt extension (although the extension does not matter).
A uniqueness database file: This file, which has a .udf extension, provides the answers to computer specific questions that will change from machine to machine (for example, the computer name). Thus it identifies names of computers.
Incorrect answers:
A: This /cmdcons switch specifies that files required for command-line repair console be installed when making use of winnt32.exe. This is not what is required; you need to completer upgrades and not repair.
C: The winnt.exe command line is used in DOS-based and 16-bit installations.
D: To use a bootable CD-ROM for a fully automated operating system installation, the answer file must be called Winnt.sif and be located on a floppy disk. This is not how the upgrade is envisaged under the given circumstances.
