Microsoft DP-420 Exam - Topic 2 Question 61 Discussion

Actual exam question for Microsoft's DP-420 exam
Question #: 61
Topic #: 2
[All DP-420 Questions]

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?

Show Suggested Answer Hide 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.

Hmm, the key here is that the runtime exception is preventing the conflicts from being resolved. I think the Azure function will need to handle that somehow.
