Exam 70-740 topic 1 question 276 discussion

The question is - you need to compile Config.ps1 so that the script can be applied to Server2 by using PowerShell DSC. - according the links provided https://docs.microsoft.com/en-us/windows/win32/wmisdk/compiling-mof-files%20 once we read through there is a link to a usage in cli for mofcomp.exe https://docs.microsoft.com/en-us/windows/win32/wmisdk/running-the-mof-compiler-on-a-file

It's D - when you run the ps1 file it gets gobbled up and spat out as a MOF... poor thing

Correct answer is D, because we have a .ps1 file ans we need to generate a .mof file to apply it to server 2. So, all we have to do is run config.ps1 to generate the .mof file. mofcomp.exe tool, only works on .mof files. See the highlighted text in the link below: https://docs.microsoft.com/en-us/windows/win32/wmisdk/mofcomp#:~:text=but%20you%20can%20also%20compile%20MOF%20files%20by%20using%20this%20tool.

If you want to pick D (config.ps1).... it should start with (. <space> config.ps1) or ( Dot Space confiig.ps1) but the D option of question does not have any (Dot Space).. So answer should be A (mofcomp.exe) Ref: https://docs.microsoft.com/en-us/powershell/scripting/dsc/configurations/write-compile-apply-configuration?view=powershell-6

If you want to pick D (config.ps1).... it should start with (. <space> config.ps1) or ( Dot Space confiig.ps1) but the D option of question does not have any (Dot Space) Ref: https://docs.microsoft.com/en-us/powershell/scripting/dsc/configurations/write-compile-apply-configuration?view=powershell-6

It's not D because it's missing the dot, space. You can't count the one after the D because all the answer choices have that format

Answer: D mvdb87 is correct, look at this URL https://docs.microsoft.com/en-us/windows/win32/wmisdk/mofcomp it states: The Managed Object Format (MOF) compiler parses a file *CONTAINING MOF statements and adds the classes and class instances defined in the file to the WMI repository..........so you need a mof file already created to use this command.

It's D. The .mof file will be generated after dot sourcing the script, so you'll have to use the config.ps1 first. The Start-DscConfiguration command is used AFTER compiling. Source: https://docs.microsoft.com/en-us/powershell/scripting/dsc/configurations/write-compile-apply-configuration?view=powershell-6 Compile the configuration For a DSC configuration to be applied to a node, it must first be compiled into a MOF file. Running the configuration, like a function, will compile one ".mof" file for every Node defined by the Node block. In order to run the configuration, you need to dot source your "HelloWorld.ps1" script into the current scope. For more information, see about_Scripts. Dot source your "HelloWorld.ps1" script by typing in the path where you stored it, after the . (dot, space). You may then, run your configuration by calling it like a Function.

Hi guys: See below link: https://docs.microsoft.com/en-us/powershell/scripting/dsc/configurations/write-compile-apply-configuration?view=powershell-6 According to what I did in my lab before, just “ . .config.ps1” can generate the mof file we need. Because you define the node in ps1 node block. Thanks.

how about D？

I think is Start-DscConfiguration

I did not find any references to mofcomp.exe for the use in question.
