You work as a desktop support technician at ABC.com. The ABC.com network consists of a
single Active Directory domain named ABC.com.
You are managing a desktop called ABC-WS680. It is running Windows Vista. You are wanting to
change the operating system to Windows 7. You have formatted the hard drive and planning to do
a clean install with automated installation.
How can you proceed with automated installation on ABC-WS680 while booting from Windows 7
DVD?

A.
By creating an answer file named sysprep.xml and copying it to a shared folder on the network.

B.
By creating an answer file named winnt.dif and copying it to an external hard disk.

C.
You should consider creating an answer file named autounattend.sif and copying it to shared
folder on the network.

D.
by creating an answer file named autounattend.xml and copying it to an external hard drive.

Explanation:
When Windows 7 is booted from the DVD, it automatically searches for an answer
file called autounattend.xml. If it finds such a file, it will use that to answer all of the configuration
questions.
