You work as a Network Administrator at ABC.com. The network contains a single Active Directory Domain
Services (AD DS) domain named ABC.com.
The network includes servers running various versions of Windows Server 2008. You plan to upgrade all
servers in the network to Windows Server 2012. Some servers run the 32-bit version of Windows Server 2008
Service Pack 2 (SP2) on hardware with x86 CPUs.
Some servers run the 64-bit version of Windows Server 2008 Service Pack 2 (SP2) on hardware with x64
CPUs.
Some servers run Windows Server 2008 R2 on hardware with x64 CPUs. Some servers run Windows Server
2008 R2 Service Pack 1 (SP1) on hardware with x64 CPUs.
Which of the servers can be upgraded directly to Windows Server 2012 without the need to purchase new
hardware or install additional service packs? (Choose all that apply)
A.
The servers running the 32-bit version of Windows Server 2008 Service Pack 2 (SP2) on hardware with x86
CPUs.
B.
The servers running the 64-bit version of Windows Server 2008 Service Pack 2 (SP2) on hardware with x64
CPUs.
C.
The servers running Windows Server 2008R2 on hardware with x64 CPUs.
D.
The servers running Windows Server 2008 R2 SP1 on hardware with x64 CPUs.
B and D
A is wrong as cannot upgrade 32bit to 64bit
C is wrong as reqs SP1
after a little research I agree with you but seemed strange 2008 SP2 is higher than 2008r2
I agree B+D, check the Upgrading to Windows Server 2012
