Question from 70-291

Tech-Archive recommends: Speed Up your PC by fixing your registry

ok let me see what choice would you guys pick here
here is question
You are the network administrator for xxxxxxx.com. The network consists of a
single Active Directory domain named xxxxxxx.com. All servers run Windows
Server 2003. All client computers run Windows 2000 Pro with SP4 or Windows XP
Pro.

You install Software Update Services (SUS) on a computer named X1. You
create a GPO that configures all client computers to receive their software
update from X1.

One week later, you run MBSA on all client computers to find out whether all
updates are being applied. You discover that all of the Win 2000 Pro client
computer receive updates, but the Win XP Pro client computers do not receive
updates.
You verify that the GPO setting was applied on all Win XP Pro computers.
You need to ensure that the Win XP Pro client computers receive their
updates from X1.
What should you do ?

A) make all users of the Win XP Pro client computers members of the
Administrators local group
B) On all Win XP Pro client computers, install SP1
C) On all win XP Pro client computers, restart Automatic Updates
D) On all Win XP Pro client computers, delete the NOAUTOUPDATE Value under
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU.

my pick is B, but the study guide that i'm using their pick is A
i pick B because scenario says that win 2000 pro clients have SP4 installed
and XP clients doesn't says anything about service packs
thanks
