NEW QUESTION # 47
You have an Azure SQL database named AdventureWorksDB that contains a table named dbo.Employee.
You have a C# Azure Functions app that uses an HTTP-triggered function with an Azure SQL input binding to query dbo.Employee.
You are adding a second function that will react to row changes in dbo.Employee and write structured logs.
You need to configure AdventureWorksDB and the app to meet the following requirements:
* Changes to dbo.Employee must trigger the new function within five seconds.
* Each invocation must processes no more than 100 changes.
Which two database configurations should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Answer: A,C
Explanation:
Azure Functions' Azure SQL trigger requires change tracking to be enabled on the source table. Microsoft's SQL trigger documentation states that setting up change tracking for the Azure SQL trigger requires two steps: enable change tracking on the database and enable change tracking on the table being monitored. Since the question asks specifically which database configurations you should perform, enabling change tracking on dbo.Employee is one of the required database-side steps.
To meet the latency requirement that changes trigger the function within five seconds, the relevant trigger setting is Sql_Trigger_PollingIntervalMs. Microsoft documents this setting as the delay, in milliseconds, between processing each batch of changes, and a value of 5000 means the trigger polls every 5 seconds.
A few clarifications about the other options:
B is not the documented setting name. The documented app setting is Sql_Trigger_BatchSize or host setting MaxBatchSize, not "SetSql Trigger MaxBatchSize". The screenshot wording suggests a distractor.
D is also required in practice for the trigger to work, but the question asks for two answers and includes the polling setting plus the table-level CT setting as the actionable choices presented.
F is wrong because the Azure SQL trigger uses change tracking, not CDC.
NEW QUESTION # 48
You have an Azure SQL database that contains a table named Customer. Customer contains the following columns:
- NationalIDNumber is unique per customer.
- InvestigationNotes contains free-form text.
You have a stored procedure that performs point lookups by NationalIDNumber and returns InvestigationNotes in the query results without filtering on InvestigationNotes.
You need to encrypt both columns by using Always Encrypted and the highest security possible.
Which type of Always Encrypted encryption should you use for each column?
Answer: D
Explanation:
To achieve the highest security for an Azure SQL Database using Always Encrypted, you must use Randomized Encryption for the InvestigationNotes and Deterministic Encryption for the NationalIDNumber.
While "Randomized" is more secure, it does not support point lookups (equality searches).
Therefore, a hybrid approach is required to maintain functionality while maximizing protection.
Recommended Encryption Settings
* NationalIDNumber
Deterministic is required to allow the Stored Procedure to perform point lookups (WHERE NationalIDNumber = @id).
* InvestigationNotes
Use randomized as it provides the highest security. It prevents pattern matching and "leakage" for sensitive text.

NEW QUESTION # 49
You have an Azure SQL database that contains a table named Rooms. Rooms was created by using the following transact-SQL statement.
You discover that some records in the Rooms table contain NULL values for the Owner field. You need to ensure that all future records have a value for the Owner field. What should you add?
Answer: B
Explanation:
The table definition allows Owner to be nullable because it was created as Owner nvarchar(100) without NOT NULL. Since the question asks what to add so that future rows must have a value, a check constraint such as CHECK (Owner IS NOT NULL) is the appropriate choice. Microsoft documents that check constraints validate future INSERT and UPDATE operations against the constraint condition.
The other options do not solve the requirement:
* A foreign key enforces referential integrity, not non-null entry by itself.
* A nonclustered index does not require values to be present.
* A unique constraint prevents duplicate values but still does not serve as the right mechanism here for enforcing presence across future writes. Microsoft's constraint documentation also notes that primary- key columns are implicitly NOT NULL, which helps distinguish nullability enforcement from other constraint types.
NEW QUESTION # 50
You are creating a table that will store customer profiles.
You have the following Transact-SQL code.
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 schema meets the security requirements for PII data. # Yes
Administrators of the Azure SQL server can see all the rows in dbo.CustomerProfiles when they use an application. # No The masking rules will apply even when row-level security (RLS) filters out rows. # No The first statement is Yes because the design combines two relevant SQL security controls for personally identifiable information: Dynamic Data Masking (DDM) on sensitive columns such as FullName, EmailAddress, and PhoneNumber, and Row-Level Security (RLS) to restrict which rows a user can access based on RegionCode. Microsoft documents that DDM limits sensitive data exposure for nonprivileged users, while RLS restricts row access according to the user executing the query. Together, these are valid and appropriate controls for protecting PII in Azure SQL Database.
The second statement is No. Administrative users can view unmasked data because administrative roles effectively have CONTROL, which includes UNMASK. However, that does not mean they automatically see all rows through the application query path defined by the RLS policy. The security policy filters rows based on SUSER_SNAME() and matching RegionCode, so row visibility is governed by the predicate unless the policy is altered or bypassed administratively. DDM and RLS solve different problems: DDM affects how returned values are shown, while RLS affects which rows are returned at all.
The third statement is No because masking only applies to data that is actually returned in the query result set.
Microsoft describes DDM as hiding sensitive data in the result set of a query. If RLS filters a row out, that row is not returned, so there is nothing left for masking to act on. In other words, RLS eliminates inaccessible rows first from the user's perspective, and DDM masks sensitive column values only on rows the user is allowed to see.
NEW QUESTION # 51
You need to use the UsefulPrompts table as defined in the AI requirements.
Which stored procedure should you use?
Answer: A
Explanation:
D). sp_invoke_external_rest_endpoint is the correct answer.
The requirement specifies that the UsefulPrompts table must store prompts that doctors can use to help diagnose patient illnesses by connecting to an Azure OpenAI endpoint.
The system stored procedure sp_invoke_external_rest_endpoint enables Azure SQL Database to invoke external HTTPS REST APIs directly through T-SQL, including Azure OpenAI services.
Technical breakdown:
* External API integration: Sends requests to an Azure OpenAI model endpoint without requiring an additional application layer.
* Prompt processing: Retrieves prompts from UsefulPrompts and constructs JSON request payloads using SQL functions such as JSON_OBJECT.
* Authentication: Supports secure endpoint authentication using database-scoped credentials and Microsoft Entra managed identities.
* Model execution: Sends HTTP POST requests containing prompts to the deployed Azure OpenAI model.
* Response processing: Captures JSON responses, which can be parsed and incorporated into database- driven AI workflows.
Microsoft documentation explicitly supports using this stored procedure to invoke Azure OpenAI REST endpoints.
Why the other options are incorrect:
* A. sp_addendpoint: Not the supported system procedure for invoking Azure OpenAI REST APIs.
* B. xp_cmdshell: Executes operating-system commands and introduces unnecessary security risks.
* C. sp_OACreate: Creates OLE Automation objects rather than providing the supported Azure SQL REST integration mechanism.

Main topic: Implement AI capabilities in database solutions.
Subtopic: Design and implement retrieval-augmented generation (RAG).
Specific examination objective: Create a prompt by using the sp_invoke_external_rest_endpoint stored procedure.
