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.
