Microsoft DP-600 Implementing Analytics Solutions Using Microsoft Fabric Exam Practice Test

In Azure DevOps workspace (project) security settings, role assignments determine access levels for groups:

Viewer (equivalent to the Readers security group): Grants read-only access to work items, code, pipelines, and other artifacts. Ideal for review-only scenarios where users need to view but not edit content.

Contributor (equivalent to the Contributors security group): Allows full edit and contribute privileges, such as updating work items, code reviews, and pipeline runs. Suitable for active participation in reviews that may involve feedback or changes.

Based on the group names implying review-focused access, Viewer fits Group1 for passive observation, while Contributor fits Group2 for interactive review tasks. These align with default Azure DevOps permissions for secure, least-privilege access.

Requirement: “The number of rows added to the Orders table during refreshes must be minimized.”

The Orders table has a sequential OrderID.

To minimize refresh size, you must only import new rows, not the entire table.

This requires retrieving the maximum OrderID currently loaded, then only loading rows with a greater OrderID.

So, the correct solution is to use a pipeline (ADF) with a dataflow to retrieve the maximum OrderID.

Answer: C. an Azure Data Factory pipeline that executes a dataflow to retrieve the maximum value of the OrderID column in the destination lakehouse

Comprehensive Detailed Explanation

From the case study:

Research division data for Productline2 is currently in CSV format in storage2.

Requirement: “All the Research division data in the lakehouses must be presented as managed tables in Lakehouse explorer.”

In Fabric lakehouses, managed tables are stored in Delta format inside the Tables folder.

Step 1: Reading the source

df = spark.read.format("csv") \

options(header="true", inferSchema="true") \

load("abfss://storage1.dfs.core.windows.net/files/productline2")

This correctly ingests the CSV source from ADLS Gen2.

Step 2: Writing to Lakehouse as a managed table

You must write the data in Delta format to ensure it is queryable and managed within the lakehouse.

The correct path is under Tables/, because this is where Fabric automatically manages Lakehouse managed tables.

The target table should be named productline2, so the correct path is:

df.write.mode("overwrite").format("delta").save("Tables/productline2")

Why not other options?

CSV or Parquet formats would not create a managed Lakehouse table; they would just create files.

Writing to productline2 directly (without Tables/) would store unmanaged files in the Lakehouse Files area, not managed tables.

Writing to Tables/research/productline2 adds an unnecessary subdirectory and is not the standard structure for managed tables.

Correct Final Code

df.write.mode("overwrite").format("delta").save("Tables/productline2")

You need to ensure that Contoso can use version control to meet the data analytics requirements and the general requirements.

Requirement: “All the semantic models and reports for the Research division must use version control that supports branching.”

Fabric supports Git integration (Azure Repos or GitHub) for semantic models and reports.

Storing in Data Lake Gen2 or OneDrive does not provide version control with branching.

The correct action is to integrate workspaces with a Git repository.

Answer: D. Modify the settings of the Research division workspaces to use an Azure Repos repository.

You need to recommend which type of Fabric capacity SKU meets the data analytics requirements for the Research division.

Requirement: “The Research division workspaces must use a dedicated, on-demand capacity that has per-minute billing.”

Fabric capacity SKUs:

F (Fabric) = dedicated Fabric capacity, available on pay-as-you-go with per-minute billing.

P (Premium) and EM are Power BI capacities (not Fabric-native).

A refers to Azure Analysis Services capacity.

The only correct option is F SKU.

Comprehensive Detailed Explanation

The question asks: Which syntax should you use in a Fabric notebook to access the Research division data for Productline1?

Key Background from the Case

In Productline1ws, a lakehouse named Lakehouse1 is created.

In Lakehouse1, a shortcut is created to storage1, named ResearchProduct.

Storage1 contains the Research division data for Productline1 in Delta format.

Requirement: All data in lakehouses must be presented as managed tables in Lakehouse explorer.

Analyzing the Syntax Options

Option A:

spark.sql("SELECT * FROM Lakehouse1.ResearchProduct")

This syntax directly queries the ResearchProduct shortcut within Lakehouse1 using Spark SQL.

Since the shortcut points to Delta data, Spark can directly query it.

This is the correct way to retrieve Productline1 data from Lakehouse1.

Option B:

spark.sql("SELECT * FROM Lakehouse1.productline1.ResearchProduct")

This introduces an extra schema-like path (productline1) that is not part of the shortcut name.

Incorrect, because the shortcut was created as ResearchProduct inside Lakehouse1, not under another schema.

Option C:

external_table('Tables/ResearchProduct')

external_table is not the correct way to access a Lakehouse shortcut.

Shortcuts in Lakehouses appear as tables and can be queried using Spark SQL directly.

Option D:

spark.sql("SELECT * FROM Lakehouse1.productline1.ResearchProduct")

Same issue as Option B, includes a schema path that does not exist.

Correct Choice

Since the shortcut to ResearchProduct was created inside Lakehouse1, and Spark SQL can query it directly, the correct syntax is:

spark.sql("SELECT * FROM Lakehouse1.ResearchProduct")

That matches Option A.

Comprehensive Detailed Explanation

The requirement is to logically group the Research division workspaces and support filtering in the OneLake data hub.

Why Domain?

Microsoft Fabric allows you to assign workspace domains (e.g., Finance, HR, Research).

This provides a logical grouping of workspaces within the organization.

Domains are the only supported way to enable filtering in OneLake data hub by department.

Capacity or tenant grouping would not allow filtering by department in OneLake.

Why OneLake data hub?

The OneLake data hub is the centralized interface to browse and discover data assets across the organization.

With workspace domains configured, users can filter directly in the OneLake data hub by domain (e.g., “Research”).

The Fabric Admin portal and Entra admin center are used for administration, not for workspace filtering in data discovery.

Correct Selection for the Hotspot

Grouping method: Domain

Tool: OneLake data hub

References

Final Answer:

Grouping method = Domain

Tool = OneLake data hub

 Calculation groups are a Tabular Object Model (TOM) feature.

 They cannot be authored in Power BI Desktop or the service.

 They are implemented using Tabular Editor.

Scenario:

Semantic model contains a measure: TotalSalesAmount.

This measure returns sales revenue translated into a selected currency.

Requirement: Format the result using the correct currency symbol dynamically.

Analysis:

Dynamic format string in DAX is specifically designed for applying formats (like currency symbols) dynamically based on slicers or calculation context.

WINDOW function → used for windowing calculations, not formatting.

Linguistic schema → used for Q&A natural language, not for formatting.

Field parameter → used to swap fields/measures dynamically, not for formatting.

Correct Answer:

A. A dynamic format string

We need to create a computed column PriceRange based on the UnitPrice column in the dbo.Product table.

Step 1: Requirements

If UnitPrice = 0 → "Not for resale"

If UnitPrice < 50 → "Under $50"

If UnitPrice >= 50 AND UnitPrice < 250 → "Under $250"

Otherwise → "$250+"

This matches a CASE expression in T-SQL.

Step 2: CASE Expression Structure

The syntax is:

CASE

WHEN condition THEN result

WHEN condition THEN result

ELSE result

END

Step 3: Apply to Problem

SELECT

Item,

UnitPrice,

PriceRange = CASE

WHEN UnitPrice = 0 THEN 'Not for resale'

WHEN UnitPrice < 50 THEN 'Under $50'

WHEN UnitPrice >= 50 AND UnitPrice < 250 THEN 'Under $250'

ELSE '$250+'

END

FROM [Warehouse1].[dbo].[Product];

Step 4: Why This is Correct

CASE starts the conditional evaluation.

ELSE handles the default branch ($250+).

END closes the expression.

Meets all requirements exactly.

You should complete the code as follows:

Table

NativeQuery

EnableFolding

In Power Query, using Table before the SQL statement ensures that the result of the SQL query is treated as a table. NativeQuery allows a native database query to be passed through from Power Query to the source database. The EnableFolding option ensures that any subsequent transformations that can be folded will be sent back and executed at the source database (Microsoft SQL Server engine in this case).

When users interact with a report built from a Direct Lake semantic model that uses row-level security (RLS), the DAX queries will operate in DirectQuery mode (A). This is because the model directly queries the underlying data source without importing data into Power BI. References = The Power BI documentation on DirectQuery provides detailed explanations of how RLS and DAX queries function in this mode.

Comprehensive Detailed Explanation

We need to write a query that summarizes order quantities by year and product, and also include the yearly total for all products in each row.

Step 1: What the query needs

Extract the year from SalesOrderDetail.ModifiedDate.

Join with the Product table to get the product name.

Aggregate with SUM(OrderQty).

Return grouped data by year and product, with an additional subtotal row per year (all products combined).

Step 2: Evaluate the SELECT Clause

We must extract the year using:

YEAR(so.ModifiedDate) AS OrderDate

This converts the ModifiedDate column into a year value for grouping.

Step 3: Evaluate the GROUP BY options

CUBE(YEAR, P.Name) → Produces all combinations of year totals, product totals, and grand totals. Too many combinations, not required.

GROUPING SETS → Could achieve the result but requires explicitly listing the sets. Less direct.

ROLLUP(YEAR, P.Name) → Produces grouping by (Year, Product) and then a subtotal per Year. Exactly what is required.

YEAR only → Would group only by year, losing per-product breakdown.

Correct: ROLLUP(YEAR(so.ModifiedDate), P.Name)

Step 4: Completed Query

SELECT

YEAR(so.ModifiedDate) AS OrderDate,

p.Name,

SUM(so.OrderQty) AS OrderQty

FROM dbo.SalesOrderDetail so

INNER JOIN dbo.Product p

ON p.ProductID = so.ProductID

GROUP BY ROLLUP(YEAR(so.ModifiedDate), p.Name);

Why This Works

YEAR(so.ModifiedDate) extracts year for grouping.

ROLLUP(YEAR, P.Name) provides both product-level totals and yearly subtotals.

Ensures the requirement: “include the yearly sum of order quantities for all the products in each row.”

Step 1: Default permissions when sharing a warehouse in Fabric

When you share a Fabric warehouse (DW1) with a user and assign them default permissions, the user:

Gets Build permission by default.

Build permission allows the user to:

Use the default dataset automatically created for the warehouse.

Build reports and dashboards against that dataset.

It does not grant direct query permissions to the underlying tables or files.

Step 2: Analyze the options

A. Build reports by using the default dataset. ✅

Correct. Sharing a warehouse gives Build permission on the warehouse’s default dataset.

User1 can create Power BI reports but cannot directly query the warehouse via SQL.

B. Read the underlying Parquet files from OneLake.

Incorrect. Access to underlying OneLake files requires Direct Lake storage access or shortcut permissions, not provided by default sharing.

C. Connect to DW1 via the TDS endpoint.

Incorrect. The TDS endpoint is supported by semantic models, not warehouses.

D. Read data from the tables in DW1.

Incorrect. Default permissions do not allow table-level SQL access. They allow using the dataset for reporting.

Step 3: Correct Answer

The only capability User1 has by default is:

A. Build reports by using the default dataset.

 The issue is that USERNAME() is returning blank in Fabric because it needs the user principal name (UPN) from Microsoft Entra ID.

 Simply creating a role in the model does not fix the problem of the identity not being surfaced.

 To solve this, you need to ensure that the Entra UPN is synced correctly (via Entra Connect attribute mappings) and use the right function (USERPRINCIPALNAME() in modern models).

 Therefore, just creating a role does not meet the goal.

We need to query a KQL database table named Readings to generate output that includes both the current reading and the previous reading values and datetime for each row.

Step 1: Understanding Requirements

The output table shows:

City, Area, MeterReading, Datetime

PrevMeterReading, PrevDatetime

The prev() function in KQL is used to access the value of a column from the previous row (based on order).

Step 2: Query Construction

We start with filtering:

Readings

| where City == "Copenhagen"

| sort by Datetime

To add columns that calculate the previous reading and previous datetime, we use extend:

| extend PrevMeterReading = prev(MeterReading), PrevDatetime = prev(Datetime)

extend creates new columns.

prev() pulls the previous row’s values.

Finally, we only want specific columns in the output. For this, we use project:

| project City, Area, MeterReading, Datetime, PrevMeterReading, PrevDatetime

Step 3: Completed Query

Readings

| where City == "Copenhagen"

| sort by Datetime

| extend PrevMeterReading = prev(MeterReading), PrevDatetime = prev(Datetime)

| project City, Area, MeterReading, Datetime, PrevMeterReading, PrevDatetime

Why This is Correct

extend adds calculated columns.

prev() gives access to the previous row.

project selects only the required columns.

This matches exactly the table shown in the question.

For the HighestSellingPrice, you should use the GREATEST function to find the highest value from the given price columns. However, T-SQL does not have a GREATEST function as found in some other SQL dialects, so you would typically use a CASE statement or an IIF statement with nested MAX functions. Since neither of those are provided in the options, you should select MAX as a placeholder to indicate the function that would be used to find the highest value if combining multiple MAX functions or a similar logic was available.

For the TradePrice, you should use the COALESCE function, which returns the first non-null value in a list. The COALESCE function is the correct choice as it will return AgentPrice if it's not null; if AgentPrice is null, it will check WholesalePrice, and if that is also null, it will return ListPrice.

The complete code with the correct SQL functions would look like this:

SELECT ProductID,

MAX(ListPrice, WholesalePrice, AgentPrice) AS HighestSellingPrice, -- MAX is used as a placeholder

COALESCE(AgentPrice, WholesalePrice, ListPrice) AS TradePrice

FROM Sales.Products

Select MAX for HighestSellingPrice and COALESCE for TradePrice in the answer area.

For the semantic model design required for the customer satisfaction report, the choices for data source authentication method and mode should be made based on security and performance considerations as per the case study provided.

Authentication method: The data should be accessed securely, and given that row-level security (RLS) is required for users executing T-SQL queries, you should use an authentication method that supports RLS. Service principal authentication is suitable for automated and secure access to the data, especially when the access needs to be controlled programmatically and is not tied to a specific user's credentials.

Mode: The report needs to show data as soon as it is updated in the data store, and it should only contain data from the current and previous year. DirectQuery mode allows for real-time reporting without importing data into the model, thus meeting the need for up-to-date data. It also allows for RLS to be implemented and enforced at the data source level, providing the necessary security measures.

Based on these considerations, the selections should be:

Authentication method: Service principal authentication

Mode: DirectQuery

Comprehensive Detailed Explanation

When assigning permissions to roles in a Fabric workspace for analytics workloads, you must align permissions with the responsibilities and tools typically used by each persona:

1. Data Engineers

Their primary tasks include building and transforming data pipelines, as well as making datasets usable by others.

The appropriate permission is Build Reports on the default dataset, because this allows them to create and manage reports using the curated semantic model while preparing data for analysts and scientists.

2. Data Analysts

Analysts work heavily with Apache Spark for exploratory analysis, cleansing, and shaping data.

The correct permission is Read All Apache Spark, as this grants them the ability to query and analyze Spark-based data directly without elevated permissions that are unnecessary for their role.

3. Data Scientists

Data scientists often use SQL analytics endpoints to run queries, train models, and integrate data into machine learning workflows.

The correct permission is Read All SQL analytics endpoint data, since it enables direct programmatic access to the SQL endpoint, which is needed for advanced modeling and experimentation.

Summary of Selections:

DataEngineers → Build Reports on the default dataset

DataAnalysts → Read All Apache Spark

DataScientists → Read All SQL analytics endpoint data

To meet the technical requirement that data loading activities must ensure the raw and cleansed data is updated completely before populating the dimensional model, you would need a mechanism that allows for ordered execution. A pipeline in Microsoft Fabric with dependencies set between activities can ensure that activities are executed in a specific sequence. Once set up, the pipeline can be scheduled to run at the required intervals (hourly or daily depending on the data source).

A lakehouse (C) should be recommended for the AnalyticsPOC workspace. It combines the capabilities of a data warehouse with the flexibility of a data lake. A lakehouse supports semi-structured and unstructured data and allows for T-SQL and Python read access, fulfilling the technical requirements outlined for Litware. References = For further understanding, Microsoft's documentation on the lakehouse architecture provides insights into how it supports various data types and analytical operations.

The PoC is planned to be completed using a Fabric trial capacity, which implies that users involved in the PoC should be able to try paid features. However, this should be limited to specific security groups involved in the PoC to prevent the entire organization from accessing these features before the trial is proven successful (A). The ability for users to create Fabric items should also be enabled for specific security groups to ensure that only the relevant team members participating in the PoC can create items in the Fabric environment (E).

You should use CREATE VIEW to make the pricing group logic available for T-SQL queries.

The CASE statement should be used to determine the pricing group based on the list price.

The T-SQL statement should create a view that classifies products into pricing groups based on the list price. The CASE statement is the correct conditional logic to assign each product to the appropriate pricing group. This view will standardize the pricing group logic across different databases and semantic models.

For ingesting customer data into the data store in the AnalyticsPOC workspace, a dataflow (D) should be recommended. Dataflows are designed within the Power BI service to ingest, cleanse, transform, and load data into the Power BI environment. They allow for the low-code ingestion and transformation of data as needed by Litware's technical requirements. References = You can learn more about dataflows and their use in Power BI environments in Microsoft's Power BI documentation.

Both a dataflow (A) and a Stored procedure activity in a pipeline (B) are capable of creating and populating a date dimension table. A dataflow can perform the transformation needed to create the date dimension, and it aligns with the preference for using low-code tools for data ingestion when possible. A Stored procedure could be written to generate the necessary date dimension data and executed within a pipeline, which also adheres to the technical requirements for the PoC.

The measure should use the AVERAGE function to calculate the average value.

It should reference the Response Value column from the 'Survey' table.

The 'Number of months' should be used to define the period for the average calculation.

To calculate the average overall satisfaction score using DAX, you would need to use the AVERAGE function on the response values related to satisfaction questions. The DATESINPERIOD function will help in calculating the rolling average over the last 12 months.
