70-158 · Question #55
You are planning to deploy Forefront Identity Manager (FIM) 2010 in your company network. You need to select a FIM topology that meets the following requirements: - Removes single points of failure…
The correct answer is A. Create two service partitions. D. Create four instances of the FIM Service by using two FIM Service Names. To meet both requirements in FIM 2010, you must create two service partitions (separating end-user from admin/sync operations) and four FIM Service instances across two FIM Service Names (eliminating single points of failure via redundancy).

Why each option
To meet both requirements in FIM 2010, you must create two service partitions (separating end-user from admin/sync operations) and four FIM Service instances across two FIM Service Names (eliminating single points of failure via redundancy).
Creating two service partitions allows FIM to separate end-user portal operations from administrative data synchronization operations, directly satisfying the requirement to isolate these workloads from one another.
Four service partitions is unnecessary and exceeds what is required; the two functional workloads (end-user and admin sync) only need two partitions to be properly separated, and adding more partitions introduces unneeded complexity.
Creating only two instances of the FIM Service (one per FIM Service Name) does not remove single points of failure, because each partition would still have only a single instance that, if it fails, makes that partition unavailable.
Creating four instances of the FIM Service using two FIM Service Names provides redundancy for each partition (two instances per partition/service name), thereby eliminating single points of failure - if one instance fails, the other in the same group continues serving requests.
