Exam MB-400 topic 6 question 6 discussion

This is correct. You can't add a primary and/or secondary entity for the associate message. If you try to do this over the Plugin Registration Tool, you will get something similar to the following message: "Invalid Primary Entity Name for Primary or Secondary Entity. Please re-enter the data".

but is there been said that there is a N:N relationship between contact and country?

For me this is the correct question as we must store it in the contact entity

I feel your answer is correct.....but not sure too.... it says it needs to be stored in "Contacts" entity...but most votes here for "Associate" :/

Yes, and an additional reason is, that the question does not say anything about a country entity. Country could be an option-set used 3 times in the contact entity.

I agree with this also. The information must be stored IN the contact entity. It doesn't say anything about association. It is increasingly apparant that these Microsoft exams are not necessarily testing knowledge of the platform, but more so on spotting small pieces of information in the questions. The requirements should be clear as the exam is not testing how well a person reads requirement, but on their knowledge of the platform.

Actually there is in some way... imagine that the customer is associating countries/regions one after another. each time he associates a region/country, a synchronous plug-in retrieves existing associations count from the appropriate table before the new association is created. if there are already 3 associations given, the synchronous plugin can cancel the operation in realtime e.g. by throwing an exception. think about it.... otherwise a customer would pick 10 countries and only 3 will be associated. how will the customer know which 3 where associated etc. etc. I think synchronous would be a more logical approach... right, guys?
