Hi, I'm planning to study for MCSE.
For the client section, I wonder if I should choose XP(270) or Vista(620)? I also see Vista in the elective section... Vista is newer, is that means I should do vista only instead of XP cuz I think XP will retire soon right?
Also in another section, I can choose either (297) or (29

. Which one is more useful? or popular in demand?
Of course, even though I'm aiming for MCSE. I want to become MCSA and MCP in the mid-way. So I need to make sure the path will satisfy all MCP, MCSA and MCSE.
Thanks.
