Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB Sample Questions (Q200-Q205):

NEW QUESTION # 200
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?

A. a function that receives items pushed from the conflicts feed and is triggered by an Azure Cosmos DB trigger
B. a function that receives items pushed from the change feed and is triggered by an Azure Cosmos DB trigger
C. a function that pulls items from the conflicts feed and is triggered by a timer trigger
D. a function that pulls items from the change feed and is triggered by a timer trigger

Answer: A

Explanation:
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.

Box 2: No
"path": "/firstName/?" is in excludePaths.
