Actual exam question for Microsoft's DP-420 exam
Question #: 46
Topic #: 9
[All DP-420 Questions]

You have an Azure Cosmos DB Core (SQL) API account that is used by 10 web apps.

You need to analyze the data stored in the account by using Apache Spark to create machine learning models. The solution must NOT affect the performance of the web apps.

Which two actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Wait, can we really use OPENROWSET with CosmosDB? Sounds risky!

I think B is unnecessary, private endpoints aren't needed here.

I’m a bit confused about the difference between OLAP and OLTP in this context. I think option E might be wrong since we need to avoid impacting performance.

I practiced a similar question where we had to connect Spark to Cosmos DB, and I feel like using cosmos.olap in an Apache Spark pool could be the right approach, which points to option A.

I'm not entirely sure, but I think creating a private endpoint could help with security and performance, so option B might be correct too.

I remember something about using Azure Synapse Link for real-time analytics, so maybe option D is one of the answers.

Hmm, I'm not sure about this. There are a lot of moving parts here with Cosmos DB, Synapse, and machine learning. I'll need to really focus and make sure I understand the implications of each option before making a decision.

I feel pretty confident about this one. I think the best approach is to use Azure Synapse Link to create an analytical store, which will allow us to analyze the data without impacting the web apps. I'll select options B and D.

Okay, I think I've got a strategy here. The key is to find a way to analyze the data without affecting the web apps. I'm leaning towards options B and D, but I'll need to research them further.

I'm a bit confused by the wording here. Do we need to use both Azure Synapse and Cosmos DB? I'll have to double-check the requirements.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about how each one might impact the web apps' performance.

I've got a strategy - I'll start by eliminating any queries that have obvious syntax errors or use invalid column names. Then I'll focus on the date comparisons and GROUP BY clauses to determine which ones will execute successfully.

I think recall is calculated as true positives divided by the sum of true positives and false negatives, but I'm not entirely sure about the values from the matrix.

Wait, we're not allowed to use the serverless SQL pool? Bummer, I was just about to whip up a sweet little view. Guess I'll have to stick with that Spark pool and cross my fingers.

Haha, no way I'm using 'cosmos.oltp' as the data source. That's like trying to race a Formula 1 car on a dirt track. Gotta use the analytical side, baby!
