NEW QUESTION # 37
You have a Microsoft SQL Server 2025 instance that contains a database named SalesDB SalesDB supports a Retrieval Augmented Generation (RAG) pattern for internal support tickets. The SQL Server instance runs without any outbound network connectivity.
You plan to generate embeddings inside the SQL Server instance and store them in a table for vector similarity queries.
You need to ensure that only a database user account named AlApplicationUser can run embedding generation by using the model.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Answer: B,E
Explanation:
Because the SQL Server 2025 instance has no outbound network connectivity , the embedding model cannot rely on a remote REST endpoint such as Azure AI Foundry or Azure OpenAI. Microsoft's CREATE EXTERNAL MODEL documentation includes a local deployment pattern using ONNX Runtime running locally with local runtime/model paths . That is the right design when embeddings must be generated inside the SQL Server instance without external network access. Microsoft explicitly documents a local ONNX Runtime example for SQL Server 2025 and notes the required local runtime setup and model path configuration.
The permission requirement is handled by granting the application user access to use the external embeddings model. Microsoft's AI_GENERATE_EMBEDDINGS documentation states that, as a prerequisite, you must create an external model of type EMBEDDINGS that is accessible via the correct grants, roles, and/or permissions . Among the choices, the exam-appropriate action is to grant execute permission on the external model project to AlApplicationUser so only that database user can run embedding generation through the model.
NEW QUESTION # 38
You have an Azure SQL database that contains a table named dbo.SupportTickets. dbo.SupportTickets contains a JSON column named Payload and a datetime column CreatedAt.
You need to generate a report for the last seven days that meets the following requirements:
* Returns exactly one row per customer per day
* For each customer and day, returns the earliest ticket
* Includes the customer ID stored in Payload
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:
Explanation:
Explanation:
* CustomerId extraction # JSON_VALUE
* Ranking function # ROW_NUMBER
* Final filter # 1
The first selection is JSON_VALUE because CustomerId is stored as a scalar property in the JSON payload at
$.customer.id . Microsoft documents that JSON_VALUE extracts a scalar value from JSON text, whereas OPENJSON is used to shred JSON into relational rows/columns.
The second selection is ROW_NUMBER . The query partitions the data by:
CAST(t.CreatedAt AS date),
JSON_VALUE(t.Payload, ' $.customer.id ' )
and orders each partition by:
t.CreatedAt ASC
Microsoft documents that ROW_NUMBER() assigns sequential numbers starting at 1 within each partition .
Therefore, the earliest ticket for each customer on each day receives rn = 1 .
The third selection is therefore 1 , because filtering with:
WHERE rn = 1
returns exactly one row per customer per calendar day-the earliest ticket in that partition.
So the completed logic is:
WITH TicketRanks AS
(
SELECT
t.TicketId,
CAST(t.CreatedAt AS date) AS TicketDate,
JSON_VALUE(t.Payload, ' $.customer.id ' ) AS CustomerId,
t.CreatedAt,
ROW_NUMBER() OVER
(
PARTITION BY
CAST(t.CreatedAt AS date),
JSON_VALUE(t.Payload, ' $.customer.id ' )
ORDER BY t.CreatedAt ASC
) AS rn
FROM dbo.SupportTickets AS t
WHERE t.CreatedAt > = DATEADD(day, -7, SYSUTCDATETIME())
)
SELECT
TicketDate,
CustomerId,
TicketId,
CreatedAt
FROM TicketRanks
WHERE rn = 1
ORDER BY TicketDate, CustomerId;
Final hotspot selections:
* First dropdown: JSON_VALUE
* Second dropdown: ROW_NUMBER
* Third dropdown: 1
NEW QUESTION # 39
Which data type is used to store vector embeddings in SQL?
Answer: C
Explanation:
Embeddings are stored as arrays or binary/vector types depending on SQL engine support.
NEW QUESTION # 40
Case Study 1 - Contoso
Existing Environment
Azure 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 FeedbackJsoncolumn has a full-text index and stores JSON documents in the following format.
The support staff at Contoso never has the UNMASKpermission.
Problem Statements
Contoso is deploying a new Azure SQL database that will become the authoritative data store for the following:
* AI 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.
You review the execution plan and discover that the plan shows a clustered index scan.
VehicleIncidentReportsoften contains details about the weather, traffic conditions, and location. Analysts report that it is difficult to find similar incidents based on these details.
Requirements
Planned Changes
Contoso wants to modernize Fleet Intelligence Platform to support AI-powered semantic search over incident reports.
Security Requirements
Contoso identifies the following security requirements:
* Restrict the support staff from viewing Personally Identifiable Information (PII) data, which is full email addresses and phone numbers.
* Enforce row-level filtering so that analysts see only incidents for the fleets to which they are assigned. The analysts can be assigned to multiple fleets.
Database Performance and 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 accuracyJSON 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 MaintenanceEventstable updates the corresponding value in the LastModifiedUtccolumn to the time of the change.
* Avoid recursive updates.
AI Search, Embeddings, and Vector Indexing
Contoso plans to implement semantic search over incident data to meet the following requirements:
* Embeddings must be stored in dedicated Azure SQL Database tables.
* Embeddings must be generated from rich natural language fields.
* Chunking must preserve semantic coherence.
* Hybrid search must combine the following:
- Vector similarity
- Keyword filtering or boosting
Development Requirements
The development team 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 FeedbackJsoncolumn of the CustomerFeedbacktable:
* 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.
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.
Answer: B,D
Explanation:
Scenario: Sometimes the ingestion pipeline fails due to malformed JSON and duplicate payloads.
Adding a CHECK constraint with ISJSON and creating a unique index on a computed hash of the payload are effective measures in Azure SQL Database to handle malformed JSON and duplicate payloads.
[E]
JSON Validation with a CHECK Constraint
You can use a CHECK constraint in conjunction with the built-in ISJSON function to ensure that only valid JSON text is stored in a VARCHAR or NVARCHAR column. The constraint automatically rejects any insert or update operation that contains malformed JSON data, preventing pipeline failures due to invalid formatting at the database level.
[D]
Deduplication with a Unique Index on a Hashed Payload
To prevent duplicate payloads, you can create a unique index on a computed column that stores a hash of the entire JSON payload or relevant business keys within the JSON.

NEW QUESTION # 41
You have a SQL database in Microsoft Fabric that uses the default settings for a newly created database and contains a table named Sales.Orders.
You have an application that uses two stored procedures to access Sales.Orders.
While monitoring database activity, you discover the following:
While monitoring database activity, you discover the following:
* sys.dm_exec_requests shows multiple sessions in a suspended state with wait_type = LCK_M_X. All the sessions show the same wait_resource, which maps to Sales.Orders, and the same nonzero blocking_session_id.
* sys.dm_exec_input_buffer(blocking_session_id, NULL) returns a last submitted command of BEGIN TRANSACTION UPDATE Sales.Orders.
* sys.dm_exec_sessions for the blocking session shows status = sleeping and open_transaction_count = 1.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
* The blocking is caused by an uncommitted explicit transaction in the blocking session that is holding locks. # Yes
* While an UPDATE operation on Sales.Orders is occurring, SELECT statements will be blocked. # No
* Joining sys.dm_tran_locks to sys.dm_exec_requests will show which session holds locks involved in the blocking chain. # Yes Comprehensive and Detailed Explanation with all Developing AI-Enabled Database Solutions documents : = The first statement is Yes . The evidence is conclusive: the blocking session is sleeping , has open_transaction_count = 1 , and its last submitted command was BEGIN TRANSACTION UPDATE Sales.
Orders . Microsoft specifically identifies a sleeping session with an open transaction as a classic blocking condition: modifications retain their exclusive locks until the transaction is committed or rolled back . The LCK_M_X waits and identical nonzero blocking_session_id values confirm that other requests are waiting for incompatible exclusive locks.
The second statement is No because READ_COMMITTED_SNAPSHOT is ON by default for SQL database in Microsoft Fabric . Under the default READ COMMITTED isolation level, reads therefore use row versioning rather than shared locks. Consequently, a normal SELECT can read the appropriate committed row version while an UPDATE holds locks, so the writer does not ordinarily block the reader. Microsoft explicitly documents RCSI as ON by default in SQL database in Microsoft Fabric .
The third statement is Yes in the context of blocking diagnostics. sys.dm_tran_locks exposes lock ownership through fields such as request_session_id , request_mode , and request_status , while sys.dm_exec_requests exposes active request and blocking_session_id information. Correlating these DMVs allows you to associate locks with sessions participating in a blocking chain. Microsoft specifically recommends sys.dm_tran_locks for determining which locks are currently held and sys.dm_exec_requests for identifying blocked and blocking sessions.
