Study for the test, not the technology.
I worked for a large computer company, and I had to have certs because the contracts we had, mostly with the government, that specified that the tech would be 'certified'. So I had Cisco, Bay/Nortel, Microsoft, Novell, and even had to have A+.
I also used to hire temps for large network roll-outs. The temp agency sent me a bunch of resumes, and I would pick the ones I thought would be a good fit. One guy had 6 of the 7 MCSE tests under his belt, so I figured he would be a good troubleshooter and to modify some units that had a unique configuration. Long story short, day #1 a PC needed extra RAM installed. He didn't have a clue where to start, and he ended up on the loading dock collapsing cardboard for the rest of the day, and I told the temp agency to send me someone else in his place.
This was on a large install where the equipment was delivered in 4 - 56' semi's and we had 3 weeks to get it all installed and on the network.
