Clustering

I understand that the 70-290 exam may contain some clustering questions. Having never used or configured clustering and finding no information in the Microsoft Course book can someone point me in the right direction for an overview and give any idea of the level of knowledge I will need?
Cheers,
Steve

I second that.
Do yourself a favor and start working on subnetting now.. Cause it takes some people (like me) forever to learn it. (I feel so retarded...)
Working back on my CCNA and then possibly CCNP.
I'm okay (fingers crossed) on subnetting. I didn't realise there would be any questions in the 70-290 about it though?
Cheers,
Steve
There aren't any questions in 290 about custome subnetting.
