Version: 4.0
New Topic: Topic 1, Contoso Case Study
Existing Environment
Contoso has an Azure subscription in North Europe that contains the corporate infrastructure.
The current infrastructure contains a Microsoft SQL Server 2017 database.
The database contains the following tables.
The FeedbackJson column has a full-text index and stores JSON documents in the following format.
The support staff at Contoso never has the unmask permission.
Requirements
Contoso is deploying a new Azure SQL database that will become the authoritative data store for the following;
Al workloads
Vector search
Modernized API access
Retrieval Augmented Generation (RAG) pipelines
Sometimes the ingestion pipeline fails due to malformed JSON and duplicate payloads.
The engineers at Contoso report that the following dashboard query runs slowly.
SELECT VehicleTd, Lastupdatedutc, EngineStatus, BatteryHealth FROM dbo.VehicleHealthSumary
where fleetld - gFleetld ORDER BV LastUpdatedUtc DESC;
You review the execution plan and discover that the plan shows a clustered index scan.
vehicleincidentReports often contains details about the weather, traffic conditions, and location.
Analysts report that it is difficult to find similar incidents based on these details.
Planned Changes
Contoso wants to modernize Fleet Intelligence Platform to support Al-powered semantic search over incident reports.
Security Requirements
Contoso identifies the following telemetry requirements:
Telemetry data must be stored in a partitioned table.
Telemetry data must provide predictable performance for ingestion and retention operations.
latitude, longitude, and accuracy JSON properties must be filtered by using an index seek.
Contoso identifies the following maintenance data requirements:
Ensure that any changes to a row in the MaintenanceEvents table updates the corresponding
value in the LastModif reduce column to the time of the change.
Avoid recursive updates.
AI Search, Embeddings, and Vector indexing
The development learn at Contoso will use Microsoft Visual Studio Code and GitHub Copilot and will
retrieve live metadata from the databases. Contoso identifies the following requirements for
querying data in the FeedbackJson column of the customer-Feedback table:
Extract the customer feedback text from the JSON document.
Filter rows where the JSON text contains a keyword.
Calculate a fuzzy similarity score between the feedback text and a known issue description.
Order the results by similarity score, with the highest score first.

QUESTION 1
You need to generate embeddings to resolve the issues identified by the analysts.
Which column should you use?

A. vehicleLocation
B. incidentDescrlption
C. incidentType
D. SeverityScore

Answer: B

Explanation:
The correct column to use for generating embeddings is incidentDescrlption because embeddings
are intended to represent the semantic meaning of rich textual content, not simple categorical,
numeric, or location-only values. Microsofts D0 study guide explicitly includes skills such as
identifying which columns to include in embeddings, generating embeddings, and implementing
semantic vector search for scenarios where users need to find similar records based on meaning
rather than exact matches.
In this scenario, analysts report that it is difficult to find similar incidents based on details such as
weather, traffic conditions, and location. Those are descriptive context elements that are typically
captured in a free-text incident description field. An embedding generated from incidentDescrlption
can encode the semantic relationships among these narrative details, making it suitable for similarity
search, semantic search, and RAG retrieval. Microsoft documentation on vectors and embeddings
explains that embeddings are generated from text data and then stored for vector search to find
semantically related items.
The other options are weaker choices:
vehicleLocation is too narrow and usually better handled with geospatial filtering, not embeddings.
incidentType is likely categorical and too low in semantic richness.
SeverityScore is numeric and not appropriate as the primary source for semantic embeddings.
Microsoft also notes that when multiple useful attributes exist, you can either embed each text
column separately or concatenate relevant text fields into one textual representation before
generating the embedding. But among the options given, the best and most exam-aligned answer is
the textual narrative column: incidentDescrlption.

QUESTION 2
You need to recommend a solution for the development team to retrieve the live metadata.
The solution must meet the development requirements.
What should you include in the recommendation?

A. Export the database schema as a .dacpac file and load the schema into a GitHub Copilot context window.
B. Add the schema to a GitHub Copilot instruction file.
C. Use an MCP server
D. Include the database project in the code repository.

Answer: C

Explanation:
The best recommendation is to use an MCP server. In the official D0 study guide, Microsoft
explicitly lists skills such as configuring Model Context Protocol (MCP) tool options in a GitHub
Copilot session and connecting to MCP server endpoints, including Microsoft SQL Server and Fabric
Lakehouse. That makes MCP the exam-aligned mechanism for enabling AI-assisted tools to work
with live database context rather than static snapshots.
This also matches the stated development requirement: the team will use Visual Studio Code and
GitHub Copilot and needs to retrieve live metadata from the databases. Microsofts documentation
for GitHub Copilot with the MSSQL extension explains that Copilot works with an active database
connection, provides schema-aware suggestions, supports chatting with a connected database, and
adapts responses based on the current database context. Microsoft also documents MCP as the
standard way for AI tools to connect to external systems and data sources through discoverable tools
and endpoints.
The other options do not satisfy the oelive metadata requirement as well:
A .dacpac is a point-in-time schema artifact, not live metadata.
A Copilot instruction file provides guidance, not live database discovery.
Including the database project in the repository helps source control and deployment, but it still does
not provide live database metadata by itself.

QUESTION 3
You need to recommend a solution that will resolve the ingestion pipeline failure issues. Which two
actions should you recommend? Each correct answer presents part of the solution. NOTE: Each
correct selection is worth one point.

A. Enable snapshot isolation on the database.
B. Use a trigger to automatically rewrite malformed JSON.
C. Add foreign key constraints on the table.
D. Create a unique index on a hash of the payload.
E. Add a check constraint that validates the JSON structure.

Answer: D, E

Explanation:
The two correct actions are D and E because the ingestion failures are caused by malformed JSON
and duplicate payloads, and these two controls address those two problems directly. Microsofts
JSON documentation states that SQL Server and Azure SQL support validating JSON with ISJSON, and
Microsoft specifically recommends using a CHECK constraint to ensure JSON text stored in a column is properly formatted.
For the duplicate-payload issue, creating a unique index on a hash of the payload is the appropriate
design. Microsoft documents using hashing functions such as HASHBYTES to hash column values, and
SQL Server allows a deterministic computed column to be used as a key column in a UNIQUE
constraint or unique index. That makes a persisted hash-based computed column plus a unique index
a practical and exam-consistent way to reject duplicate payloads efficiently.
The other options do not solve the stated root causes:
Snapshot isolation addresses concurrency behavior, not malformed JSON or duplicate payload detection.
A trigger to rewrite malformed JSON is not the right integrity control and is brittle.
Foreign key constraints enforce referential integrity, not JSON validity or duplicate-payload prevention

QUESTION 4
HOTSPOT
You need to meet the development requirements for the FeedbackJson column
How should you complete the Transact SQL query? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
JSON_VALUE(f.FeedbackJson, '$.text') AS FeedbackText
CONTAINS(FeedbackJson, @Keyword)
SimilarityScore
These three selections are the correct way to complete the query because they align exactly with the
stated requirements for the FeedbackJson column.
First, to extract the customer feedback text from the JSON document, the correct expression is
JSON_VALUE(f.FeedbackJson, '$.text') AS FeedbackText. Microsoft documents that JSON_VALUE is
used to extract a scalar value from JSON, while JSON_QUERY is used for returning an object or array.
Since $.text is the textual feedback string, JSON_VALUE is the correct function.
Second, to filter rows where the JSON text contains a keyword, the best choice is
CONTAINS(FeedbackJson, @Keyword). The scenario explicitly states that FeedbackJson already has a
full-text index, and Microsoft documents that CONTAINS is the full-text predicate used in the WHERE
clause to search full-text indexed character data. That makes it more appropriate than using
EDIT_DISTANCE for keyword filtering.
Third, to order the results by similarity score, highest first, the correct item is SimilarityScore in the
ORDER BY clause, which would be paired with DESC in the query. This matches the requirement to
sort by the computed fuzzy similarity value. The D0 study guide specifically includes writing
queries that use fuzzy string matching functions such as EDIT_DISTANCE, which supports the earlier
computed SimilarityScore expression in the query.

QUESTION 5
DRAG DROP
You need to meet the database performance requirements for maintenance data
How should you complete the Transact-SQL code? To answer, drag the appropriate values to the
correct targets. Each value may be used once, more than once, or not at all. You may need to drag
the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:
ON â†’ m.maintenanceId = i.maintenanceId
WHERE â†’ m.LastModifiedUtc <> i.LastModifiedUtc
The correct drag-and-drop completion is:
ON m.maintenanceId = i.maintenanceId
WHERE m.LastModifiedUtc <> i.LastModifiedUtc
This satisfies the requirement to ensure that when a row in MaintenanceEvents changes, the
corresponding LastModifiedUtc value is updated to the current system time, while also helping avoid
unnecessary repeat updates.
The inserted pseudo-table in a SQL Server AFTER UPDATE trigger contains the rows that were just
updated. To update the matching row in the base table correctly, the trigger must join the target
table row to the corresponding row in inserted by the tables primary key. In this schema,
MaintenanceId is the primary key for MaintenanceEvents, so the correct join is m.maintenanceId =
i.maintenanceId. Joining on VehicleId would be incorrect because multiple maintenance rows could
exist for the same vehicle, which could update unintended rows. Microsofts trigger documentation
explains that inserted and deleted are used to work with the affected rows and that multi-row logic
should be based on proper key matching.
The WHERE m.LastModifiedUtc <> i.LastModifiedUtc predicate is used to prevent the trigger from reupdating
