Thanks for the feedback and I agree that in practice I would prefer to run Exchange 2000 on a active / passive cluster. Now with Exchange 2003 on a three node or larger cluster with one of the servers as a passive node assigned to failover for either active node that may fail, I am sure is an even better solution. However in the case of this test question on the 70-285 exam, which choice would be correct?

One of the test questions asked about hosting mailboxes on either an Active / Active Exchange Cluster or an Active / Passive Exchange Cluster which one be the correct choice? Any one pass this test and know the correct answer? My understanding is that Microsoft no longer recommends using Exchange in an Active / Active Cluster ( At least with version 2000 ) however I have not had an opportunity to try this with Exchange 2003. Any one running an Active / Active Exchange 2003 Cluster and how is working? Does it failover correctly and failback with out any issues?
