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.

C.

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”:

A & D
A : According to the link below, you enter the GUID without any dashes
D : You use the MAC preceded by twenty 0’s

However according to TechNet (https://technet.microsoft.com/en-us/library/cc754469.aspx)
5.In the text box, type the 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}.
Right, but the curly brackets are required if you use the dashes, and that’s not one of the options.
OK, has someone tried doing it with no curly brackets and no dashes?
Ok, there are 4 possible ways to enter the GUID, so here’s what happens when you try each in the WDS console
No curly brackets & no dashes – accepts it, but if you check after the prestaged device is created the Device ID has been corrupted
No curly brackets & dashes – works
Curly brackets & no dashes – can’t click next on wizard as it doesn’t recognise it as a valid device ID
Curly brackets & dashes – works
So, you need use the dashes, either with or without the curly brackets, so B is the correct answer.
The results are a bit different if the computer is pre-staged through ADUC, but answer A will still not work properly. Check the link from PerkyJerky and you can see that the GUID in the 7th image does not match the one he entered.
VM diplays GUID string format. so, B is good option.
The answers are B and D.

Correct format :
Mac address => 0000000000000000000000155D000F13 / 00155D000F13 / 00-15-5D-00-0F-13
GUID => 979708BF-C04B-4525-9FE0-C4150BB6C618 / {979708BF-C04B-4525-9FE0-C4150BB6C618}
