After finishing my MCSA exams, I went to learn something was totally new for me, I've heard about ConfigMgr before, but never used it, they used to call it SMS before, but now it's well known as ConfigMgr, and SCCM (
System Center Configuration Manager),
There is officially one exam from Microsoft for SCCM, 70-243,Administering and Deploying System Center 2012 Configuration Manager, exam link: https://www.microsoft.com/learning/en-us/exam-70-243.aspx
I've looked over a week for materials, the MVA course starts in a weird way that I could not understand anything :), it may be intended for experienced ConfigMgr admins, anyways, take a look at this TechNet article, very useful (except the MVA part, at least for me):

I've also found a great and long long discussion on a LinkedIn group about materials for SCCM, as the time of writing this, the discussion has 171 comments, which most of them are useful, here you go:

The very first thing to know is how to install SCCM on your machine, I found this great video, which by coincidence, the guy faced two issues while installing SCCM and had to troubleshoot that in the video, very informative:

Now once you have everything ready, take a look at this blog, I believe this amazing guy spent hundreds of hours creating this blog, with so much information about almost everything in SCCM:

One last website to share, here is some informative pages from Illinois State University, which happens to have a good related pages about installing software and application in SCCM:

Last thing to mention, CBT nuggets are also useful and have a solid information about SCCM, enjoy,
I hope this post will get you on the way to learn SCCM, feel free to contact me if you have any questions,
Thanks,
