Hey Guys I am due to start studying my CCNA in September at Uni I want to also get a microsoft exam under my belt before I start I am looking at the self study route for Microsoft as I recently was quoted a price for the MCSA of nearly 4k

The exam I am looking at to get before the CCNA is 70-270 I have worked as 1st line support techy and a I.T techinician and have been in the I.T sector for coming up 4 years now, I feel at ease using Xp and realistically if I set my mind to it could hammer through this exam if I put the effort in.
My question is how long would it take me to get the 70-270 secondly is it a good idea to get this before I am due to start my CCNA i just want to build up a diverse range of certs to make my cv stand out the eventual aim after the CCNA would be to become MCSA qualified and get the 3 remaining Microsoft certs.
Am I being a idiot and should just stick to the CCNA for now? lol
