You manage a server that runs Windows Server 2012 R2. The server has the Windows Deployment
Services server role installed.
You start a virtual machine named VM1 as shown in the exhibit. (Click the Exhibit button.)
You need to configure a pre-staged device for VM1 in the Windows Deployment Services console.
Which two values should you assign to the device ID? (Each correct answer presents a complete
solution. Choose two.)
A.

B.
979708BF-C04B-4525-9FE0-C4150BB6C618
C.
00155D000F1300000000000000000000
D.

E.
00000000-0000-0000-0000-C4150BB6C618
Explanation:
Use client computer’s media access control (MAC) address preceded with twenty zeros or the
globally unique identifier (GUID) in the format: {XXXXXXXX-XXXX-XXXX-XXX-XXXXXXXXXXXX}.httpHYPERLINK “http://technet.microsoft.com/en-us/library/cc754469.aspx#_blank”:

Answer is correct.
MAC address must be preceded with 20 zeros.
GUID has to be entered with the “dashes”.
If entering a GUID like in answer “A”, the Device ID is changed when you view the properties of the pre-staged computer object. I imagine this is because it hasn’t been entered in the correct format.
As an example – when I entered answer A as the guid – it saved the GUID as {BF089797-4BC0-2545-9FE0-C415OBB6C618}; which you can see is incorrect.
Answer B & D
Pay attention that in the explanation and in ref article the GUID is in brackets {} but in answers we don’t have such options. The right entering GUID without brackets should be also without dashes.
Shelchek is correct and the given answer is wrong.
See http://morgansimonsen.com/2010/06/19/windows-deployment-service-pre-staging-and-guids-2/
I think the clue is that we are dealing with a 32-bit number
for MAC 20 + 12 = 32
00000000000000000000 + 00155D000F13 = 0000000000000000000000155D000F13
and for GUID, will you need 32 digits
the following is 38 char {979708BF-C04B-4525-9FE0-C4150BB6C618}
so, the { & – – – – } gets removed to create a 32 char value
like this
GUID = 979708BFC04B45259FE0C4150BB6C618
A & D are correct

B & D
Guid can have dashes, see below
https://technet.microsoft.com/en-us/library/cc754469(v=ws.11).aspx
Answer D is OK, no problems here.
In the GUID part you have two options for entering in “This is a managed computer” window when pre-staging computer in ADUC. Either in “GUID string” format or in “Binary octet string format”.
This is a Hyper-V VM PXE Boot (from screenshot) which shows you GUID exactly in “GUID String” format.
So in this case you can enter ONLY either “{979708BF-C04B-4525-9FE0-C4150BB6C618}” or “BF0897974BC02545E09F18C6B60B15C4” (converted).
If you enter as said in answer A then you get GUID=BF089797-4BC0-2545-E09F-18C6B60B15C4 (converted back) which is incorrect.
I guess answer B has typo, it should be in {…} format which will be accepted and correct.
B & D are the correct answer based on MS documentation.
In actuality A, B, and D will work.
