Actual exam question for Microsoft's DP-700 exam

Question #: 2
Topic #: 2

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 a Fabric eventstream that loads data into a table named Bike_Location in a KQL database. The table contains the following columns:

You need to apply transformation and filter logic to prepare the data for consumption. The solution must return data for a neighbourhood named Sands End when No_Bikes is at least 15. The results must be ordered by No_Bikes in ascending order.

Solution: You use the following code segment:

Does this meet the goal?

AYes

Bno

Show Suggested Answer

Suggested Answer: B

This code does not meet the goal because this is an SQL-like query and cannot be executed in KQL, which is required for the database.

Correct code should look like:

Wait, are we sure it orders correctly?

I think it might miss some edge cases though.

The code filters for Sands End and No_Bikes >= 15.

I believe the ordering is correct, but I’m uncertain if the filter for Sands End is applied correctly in the code.

I feel like the transformation part is missing in this solution. It might not meet the goal as expected.

I remember a similar question where we had to order results, but I can't recall if we needed to use "asc" or "desc" for this one.

I think the code should filter for the neighbourhood correctly, but I'm not sure if it handles the No_Bikes condition properly.

This seems straightforward enough. I'll start by reviewing the table structure and column names, then build out the KQL query to meet the requirements. The key will be getting the filtering and ordering right.

Okay, let's break this down step-by-step. First, I need to filter the data to only include rows where the neighborhood is "Sands End" and the No_Bikes value is at least 15. Then I'll order the results by No_Bikes in ascending order. I think I can do this with a combination of the where() and order_by() functions.

Hmm, I'm a bit unsure about the "unique solution" part of the question. Does that mean there's only one correct way to solve this, or could there be multiple valid approaches? I'll need to think through the problem carefully.

This looks like a straightforward data transformation and filtering task. I'll focus on understanding the requirements and then applying the appropriate KQL commands to get the desired output.

Ah, the age-old question of whether to order by ascending or descending. The answer is simple: whichever way makes the data most useful for the end user. Unless they're a bike thief, in which case they'll want the neighbourhoods with the least bikes.

This is a trick question, isn't it? There's gotta be a catch somewhere. Maybe the data is updated in real-time and the results change by the time we run the query.

Wait, why are we ordering by No_Bikes in ascending order? Shouldn't we want the neighbourhoods with the most bikes at the top?

I don't know, the code looks a little too simple. Are we sure it covers all the requirements? What if there are other neighbourhoods with at least 15 bikes?

I agree with Sherita, the code segment orders the results by No_Bikes in ascending order as required.

Sherita

Yes, because the code segment filters data for Sands End with at least 15 bikes.

The code segment looks good to me. It filters the data for the Sands End neighbourhood and orders the results by No_Bikes in ascending order. Seems like it meets the goal.
