Microsoft Exam DP-420 Topic 2 Question 61 Discussion

Actual exam question for Microsoft's DP-420 exam

Question #: 61
Topic #: 2

You have an Azure Cosmos DB Core (SQL) API account that uses a custom conflict resolution policy. The account has a registered merge procedure that throws a runtime exception.

The runtime exception prevents conflicts from being resolved.

You need to use an Azure function to resolve the conflicts.

What should you use?

Aa function that pulls items from the conflicts feed and is triggered by a timer trigger

Ba function that receives items pushed from the change feed and is triggered by an Azure Cosmos DB trigger

Ca function that pulls items from the change feed and is triggered by a timer trigger

Da function that receives items pushed from the conflicts feed and is triggered by an Azure Cosmos DB trigger

Show Suggested Answer

Suggested Answer: D

The Azure Cosmos DB Trigger uses the Azure Cosmos DB Change Feed to listen for inserts and updates across partitions. The change feed publishes inserts and updates, not deletions.

I don't know about you, but I'm feeling a bit 'conflicted' about this question. Option B is the way to go, though.

This is a classic case of 'the solution is right in front of you.' Option B is the winner, my friends.

I think we should use option B, a function triggered by an Azure Cosmos DB trigger.

Haha, I bet the developer who wrote that runtime exception is regretting it now. Option B is the answer, no doubt about it.

I agree, that developer must be kicking themselves. Option B is definitely the way to go.

I think option D is the way to go. Receiving the items directly from the conflicts feed and resolving them in the function sounds like the best solution.
