Add a VMware Exam Blueprint Guide recommended readings to iTunes using PowerShell

Although I have been working as a VMware vSphere systems admin for more than two years now, I still don’t hold any VMware certification. The main reason for this was, that I didn’t take any VMware training course. And you won’t be VMware certified, if you haven’t at least followed one VMware training. In june I took the “VMware vSphere: Troubleshooting” class. So the reason for not doing a VMware exam was gone. And now I need to get prepared for the VMware VCP4 exam.

As you might now, if you want to prepare yourself for a VMware exam, you need to start with downloading the Exam Blueprint Guide. This guide describes what you should know to pass the exam. In this guide there are references to VMware documentation you should read before taking the exam. And I would love to read all these documents on my iPad. Being a PowerShell scripter I didn’t want to download all these documents and add them to my iTunes library manually. So I wrote a Powershell function to do that for me.

To download a VMware Exam Blueprint Guide you should go to the VMware Certification website:
http://mylearn.vmware.com/portals/certification/. There you should login using a VMware myLearn Login account. So VMware will know who downloads the Blueprint Guides. After you have downloaded the Blueprint Guide, you can use the PowerShell function Add-BlueprintToiTunes from Listing 1, to download all the recommended readings. For those people that don’t use iTunes the function has a DownloadOnly parameter. If you specify this parameter the function will only download the documents and not try to add them to iTunes. If you are using iTunes and want to add the documents to an iTunes library, you can specify the iTunes library name where the documents should go to. This will probably be the library called Books. Or the translation of the English word books in your own language. Being Dutch the library is called “Boeken” for me.

I have tried the Add-BlueprintToiTunes function with all the VMware Exam Blueprint Guides I could download. Unfortunately there were only three guides that the function worked with: VCP4, VCAPDCA and VCAPDCD. These were the only Blueprint Guides that contain clickable links to the documentation. I hope the VCP5 Blueprint Guide will contain these clickable links as well after vSphere 5 is released.

All the relevant documentation, including examples, of the Add-BlueprintToiTunes function is in the comment-based help inside the function.

After you have run the function and added all the documents to your iTunes library, all you have to do is synchronize your iPad and start reading the documents.

Update:
Today I tried this function with the VCP5 Blueprint Guide. Unfortunately this pdf has a different format and the function does not work with the VCP5 Blueprint Guide.

      Date:    31-Jul-2011
      Version: 1.0
	
      I have tested this function with all the VMware Exam Blueprint Guides.
      The only ones that contain links to online documentation and work with this function are:
      VCP4, VCAPDCA and VCAPDCD.
      Probably VCP5 will work when VMware vSphere version 5 is released.
	  
      Unfortunately iTunes does not copy the title and header tags that are in the books.
      I couldn't find a way to change these tags in iTunes from this script.
