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.

Option B seems the most straightforward approach. Using the Azure Cosmos DB trigger to handle the conflicts feed is the logical choice here.

I'm not sure, but I think A could also work since it pulls items from the conflicts feed.

I agree with Apolonia, because the function needs to receive items pushed from the change feed.
