Microsoft DP-420 Exam - Topic 3 Question 64 Discussion

Actual exam question for Microsoft's DP-420 exam

Question #: 64
Topic #: 3

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have an Azure Cosmos DB Core (SQL) API account named account 1 that uses autoscale throughput.

You need to run an Azure function when the normalized request units per second for a container in account1 exceeds a specific value.

Solution: You configure an application to use the change feed processor to read the change feed and you configure the application to trigger the function.

Does this meet the goal?

AYes

BNo

Show Suggested Answer

Suggested Answer: B

Instead configure an Azure Monitor alert to trigger the function.

You can set up alerts from the Azure Cosmos DB pane or the Azure Monitor service in the Azure portal.

Not sure if this meets the goal, seems a bit off.

Wait, can the change feed really trigger functions?

I feel like this is similar to a question we did in class, but I can't recall if the change feed is the best way to handle this specific scenario.

I’m a bit confused; I thought the change feed was more about tracking changes rather than monitoring throughput.

I remember a practice question where we had to trigger functions based on metrics, and I feel like this might not be the right approach for that.

I think using the change feed processor could work, but I'm not entirely sure if it directly relates to monitoring request units.

Hmm, I'm a little confused by the wording of the question. What exactly does "normalized request units per second" mean? I'll need to double-check the Cosmos DB documentation to make sure I fully understand that concept before I can confidently evaluate the proposed solution.

Okay, this looks like a pretty standard Azure Cosmos DB monitoring and alerting scenario. The change feed processor is definitely the way to go here. I'd just need to make sure I configure the trigger condition correctly to watch for the specific normalized RU/s value.

I'm a bit unsure about this one. Monitoring the change feed and triggering a function sounds like the right idea, but I'm not sure if that's the only way to solve this problem. I'll need to think it through a bit more to make sure I understand all the options.

I think the solution provided in the question looks like a good approach. Using the change feed processor to monitor the container's normalized request units per second and triggering an Azure function when it exceeds a specific value seems like a straightforward way to meet the goal.

Haha, this reminds me of that time I tried to monitor my coffee consumption by setting up a function to alert me every time I brewed a new pot. The change feed is way more useful than that, though!

Definitely a good solution. The change feed is perfect for this use case, and setting up the function to be triggered automatically is a nice touch. I like how it's all automated.

I agree with Emerson. The change feed processor is a powerful tool for detecting changes in Cosmos DB, and using it to trigger a function is a clever solution. It should meet the goal effectively.

I think the solution is good, as it directly addresses the requirement of running the Azure function when the request units per second exceed a specific value.

This solution seems like a solid approach. Using the change feed processor to monitor the container's request units and triggering a function when the threshold is exceeded is a great way to automate the monitoring process.
