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

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

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

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

A seems interesting, but I wouldn't trust it for conflicts.

Wait, can you really use a timer trigger for this? Sounds off.

I think C could work too, but not as efficient.

I believe option B sounds correct since it mentions being triggered by the conflicts feed, which seems relevant to resolving conflicts directly.

I'm a bit confused about the difference between the change feed and conflicts feed. I feel like I might mix them up in the exam.

I think we practiced a similar question where we had to choose between triggers. If I recall, the conflicts feed is the right one to use here.

I remember something about using the conflicts feed, but I'm not sure if it should be a pull or push method.

Based on the information provided, I believe the correct answer is option B. Receiving items pushed from the conflicts feed and using an Azure Cosmos DB trigger seems like the most direct way to resolve the conflicts.

I'm a bit confused on the difference between the change feed and the conflicts feed. I'll need to review the Azure Cosmos DB documentation to make sure I understand the right approach.

Okay, let's see here. I think the key is to use the conflicts feed to resolve the conflicts, since the runtime exception is preventing the custom merge procedure from working.

Hmm, this seems like a tricky one. I'll need to carefully consider the options and think through the implications of each approach.

Ah, the old 'runtime exception preventing conflict resolution' trick. Classic Azure Cosmos DB. Definitely going with B, the Cosmos DB trigger function.

Haha, I bet the person who wrote this question is a real conflict junkie. But I digress, B is the answer, no doubt about it.

Wait, why would I want to pull items from the change feed? That's not gonna help me resolve the conflicts caused by the runtime exception. Gotta go with B, the Cosmos DB trigger.
