Going through exam dumps of 70 - 667 and confused with this question,
You configure a SharePoint server 2010 Service Pack 1 (Sp1) farm.
You need to use the search scope across multiple farms.
What should you do?
Claimed Answer is :
Deploy multiple instances of the same service in a farm and assign unique names to the resulting service applications.
Can someone explain the reason of the answer please, As I think we can publish existing search application to farm 2 using Manage Meta Data Service and that..
