70-642

Hi all,

I'm new in this forum... I am studying for a while to my MCITP-SA. I decided to start this adventure and take the 70-642 exam first. Anyone who made this exam can give any tips? Any tipe of material that helped you in this exam? What is the subject (DNS,DHCP, etc) that is approched mostly? (sorry for my bad english)
Thanks in advance
