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?

 Exchange cluster models

Active/Passive is the strongly preferred model
  Fewer EVS' than nodes
  Must use if more than two nodes
Active/Active is the strongly discouraged model
  Maximum of two nodes and maximum of two EVS'
  Maximum one RSG per cluster (824126)
  Limits number of concurrent MAPI users per node to 1,900
  Limits average CPU utilization on each node to 40%
  Two instances of store running in one Store.exe process; not enough
contiguous virtual memory to bring &#x0;B;resource online

We have been using Active/Active for 3 years, no problems. We used
Exchange 2000 and upgraded to Exchange 2003. No problems at all.

Greetings, 

I just took the 70-285 exam yesterday.  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?

The correct technical term for haggis stalking is "havering".
