Finally passed the last exam for the Enterprise Messaging Administrator 2010 - I started at "0" back in August (haven't played with Exchange since 5.5) and studied 10-15 hours / week since ..
I am also running now my own Exchange server in our datacenter for all my private emails ... Setup has two server running the CAS and HT role where the two CAS server are in a CASArray and loadbalanced using a HA Pair of Zeus Loadbalancer, two MB server in a DAG and two Edge server with GFI installed. Plus two DCs obviously.
The whole lot is installed on two ESX Server in different datacenter running on Dell Equallogic SANs and is being backed up using Veeam B&R5
I think I can consider myself lucky to have access to so many resources, I am sure I wouldn't be able to pass that exam without it.
I am working in a hosting company and I am the VMWare guy here so I have all necessary resources at my disposal, plus my company bought every book I wanted, bought the Trainsignal and CBT Nuggets DVDs and so on ... They even bought a SAN certificate for me so I can test that properly (funny through how many loops they jump if they want someone to have that exam

)
So yea - that chapter is done .. The bad thing - the directors board now decided to use Open Exchange :-\ ... I love Exchange (second love after VMWare) so I am sure I will keep working on / with it ... (obviously, since now my private email is using it lol).
