Developing AI-Enabled Database Solutions DP-800 Practice Test 47

Question 460

A regression is reported after deployment: Blindly committing inside every CATCH block can fail or preserve partial work. The actual requirement is: A stored procedure catches a transaction error and must decide whether the transaction is committable before cleanup. Which corrective implementation addresses the cause?

  1. Use JSON_QUERY with the appropriate path to return the nested JSON fragment
  2. Use supported JSON_OBJECT construction with named properties
  3. Use REGEXP_REPLACE with a reviewed pattern and replacement expression
  4. Inspect XACT_STATE in CATCH and roll back an uncommittable transaction

Explanation

Correct Answer

D:

Inspect XACT_STATE in CATCH and roll back an uncommittable transaction. XACT_STATE distinguishes active committable and uncommittable transaction states. This directly corrects the observed failure, and success can be checked because an induced error leaves no half-committed changes and the original error is surfaced.

Incorrect Answers

A:

JSON_QUERY returns an object or array fragment rather than the scalar extracted by JSON_VALUE. Although relevant to a SQL API must extract a nested JSON array of product attributes from each payload while preserving it as valid JSON, not a quoted scalar string, this action would not correct the recorded production failure: blindly committing inside every CATCH block can fail or preserve partial work. Use the target remedy instead.

B:

Native JSON constructors handle escaping and represent values structurally. Although relevant to a SQL API needs to return one structured JSON object per customer instead of manually building a quoted string, this action would not correct the recorded production failure: blindly committing inside every CATCH block can fail or preserve partial work. Use the target remedy instead.

C:

Regular-expression replacement transforms matched substrings according to the pattern. Although relevant to a contact normalization job must remove punctuation from legacy phone strings using supported regex replacements, this action would not correct the recorded production failure: blindly committing inside every CATCH block can fail or preserve partial work. Use the target remedy instead.

Question 461

Before approving the database change, the architect reviews this case: A developer asks a coding assistant to generate dynamic SQL by interpolating an untrusted customer search string. Which implementation best satisfies this requirement?

  1. Require parameterization and test AI-generated SQL against injection cases
  2. Enable the organization-approved Copilot integration and retain code-review and validation requirements
  3. Place explicit SQL conventions in the supported GitHub Copilot instructions file and review their use
  4. Enable the supported Copilot experience under approved tenant settings and review proposed output before execution

Explanation

Correct Answer

A:

Generated code must meet the same injection and authorization standards as hand-written code. For this stated production need, the recommended implementation is: Require parameterization and test AI-generated SQL against injection cases. Evidence to look for: a quote-containing input stays data and cannot append additional sql commands.

Incorrect Answers

B:

AI code completion helps draft SQL but does not replace authentication, permissions or testing. That method solves a different requirement: a SQL team wants contextual AI code suggestions inside its approved repository workflow while retaining human review of generated queries. The current case instead requires require parameterization and test AI-generated SQL against injection cases.

C:

Repository instruction files supply durable guidance to code assistance sessions. That method solves a different requirement: a repository has conventions requiring parameterized queries, predictable object naming and no embedded secrets in generated SQL. The current case instead requires require parameterization and test AI-generated SQL against injection cases.

D:

Tenant governance and human validation limit risky generated actions. That method solves a different requirement: an organization enables code assistance in Fabric notebooks and wants generated database statements to remain under least privilege. The current case instead requires require parameterization and test AI-generated SQL against injection cases.

Question 462

The security and data engineering reviewers accept this action: Require parameterization and test AI-generated SQL against injection cases. Given that a developer asks a coding assistant to generate dynamic SQL by interpolating an untrusted customer search string. Which technical principle most directly explains why it works?

  1. Tool selection and invocation policy control actions the assistant may request
  2. Generated code must meet the same injection and authorization standards as hand-written code
  3. MCP server registration does not replace data plane permissions and source governance
  4. Auditing tool calls provides traceability beyond the natural-language prompt

Explanation

Correct Answer

B:

Generated code must meet the same injection and authorization standards as hand-written code. This explains why the selected approach meets the requirement rather than merely changing a nearby service. A confirming observation is: a quote-containing input stays data and cannot append additional sql commands.

Incorrect Answers

A:

Tool selection and invocation policy control actions the assistant may request. That principle is applicable when a developer uses an AI-assisted SQL chat and needs to prevent the model from executing schema-changing operations without consent. It does not explain the selected change in the current case, which depends on generated code must meet the same injection and authorization standards as hand-written code.

C:

MCP server registration does not replace data plane permissions and source governance. That principle is applicable when a Fabric lakehouse MCP server offers data tools but a coding assistant must not query sensitive data outside the approved workspace. It does not explain the selected change in the current case, which depends on generated code must meet the same injection and authorization standards as hand-written code.

D:

Auditing tool calls provides traceability beyond the natural-language prompt. That principle is applicable when a team must audit which SQL schemas were exposed through an MCP endpoint to an AI developer tool. It does not explain the selected change in the current case, which depends on generated code must meet the same injection and authorization standards as hand-written code.

Question 463

An incident post-change check is required for this fix: Require parameterization and test AI-generated SQL against injection cases. The check must catch this potential failure: AI-generated code is not inherently safe from SQL injection. Which observed outcome demonstrates the desired behavior?

  1. Schema discovery succeeds but a DML tool call is denied
  2. A read-only schema query works while an unauthorized write tool is denied
  3. A quote-containing input stays data and cannot append additional SQL commands
  4. New assistant sessions produce suggestions matching the documented project rules

Explanation

Correct Answer

C:

A quote-containing input stays data and cannot append additional SQL commands. This is the direct acceptance criterion because generated code must meet the same injection and authorization standards as hand-written code. The validation should also distinguish the failure condition: aI-generated code is not inherently safe from SQL injection.

Incorrect Answers

A:

Schema discovery succeeds but a DML tool call is denied. That observation would validate a different requirement: an MCP tool can read production schema and execute writes, but the SQL developer only needs read-only planning support. Here the required evidence is a quote-containing input stays data and cannot append additional SQL commands.

B:

A read-only schema query works while an unauthorized write tool is denied. That observation would validate a different requirement: a Copilot session must inspect schema metadata from a permitted SQL Server MCP endpoint with least privilege. Here the required evidence is a quote-containing input stays data and cannot append additional SQL commands.

D:

New assistant sessions produce suggestions matching the documented project rules. That observation would validate a different requirement: copilot repeatedly suggests unapproved naming and schema conventions after developers open new chat sessions. Here the required evidence is a quote-containing input stays data and cannot append additional SQL commands.

Question 464

The operational test fails because: AI-generated code is not inherently safe from SQL injection. The actual requirement is: A developer asks a coding assistant to generate dynamic SQL by interpolating an untrusted customer search string. Which corrective implementation addresses the cause?

  1. Configure an approved MCP connection with scoped database credentials and permitted tool calls
  2. Enable the supported Copilot experience under approved tenant settings and review proposed output before execution
  3. Register only the approved server endpoint with workspace-scoped authorization and minimal accessible tools
  4. Require parameterization and test AI-generated SQL against injection cases

Explanation

Correct Answer

D:

Require parameterization and test AI-generated SQL against injection cases. Generated code must meet the same injection and authorization standards as hand-written code. This directly corrects the observed failure, and success can be checked because a quote-containing input stays data and cannot append additional SQL commands.

Incorrect Answers

A:

An MCP server offers structured tools, while the connection policy determines what the assistant can access. Although relevant to a Copilot session must inspect schema metadata from a permitted SQL Server MCP endpoint with least privilege, this action would not correct the recorded production failure: aI-generated code is not inherently safe from SQL injection. Use the target remedy instead.

B:

Tenant governance and human validation limit risky generated actions. Although relevant to an organization enables code assistance in Fabric notebooks and wants generated database statements to remain under least privilege, this action would not correct the recorded production failure: aI-generated code is not inherently safe from SQL injection. Use the target remedy instead.

C:

MCP server registration does not replace data plane permissions and source governance. Although relevant to a Fabric lakehouse MCP server offers data tools but a coding assistant must not query sensitive data outside the approved workspace, this action would not correct the recorded production failure: aI-generated code is not inherently safe from SQL injection. Use the target remedy instead.

Question 465

A cross-functional engineering review records the following need: An organization enables code assistance in Fabric notebooks and wants generated database statements to remain under least privilege. Which implementation best satisfies this requirement?

  1. Enable the supported Copilot experience under approved tenant settings and review proposed output before execution
  2. Require parameterization and test AI-generated SQL against injection cases
  3. Remove secrets and sensitive customer data and use only an organization-approved AI assistance boundary
  4. Register only the approved server endpoint with workspace-scoped authorization and minimal accessible tools

Explanation

Correct Answer

A:

Tenant governance and human validation limit risky generated actions. For this stated production need, the recommended implementation is: Enable the supported Copilot experience under approved tenant settings and review proposed output before execution. Evidence to look for: assistive suggestions are available only to authorized users and deployment is reviewed.

Incorrect Answers

B:

Generated code must meet the same injection and authorization standards as hand-written code. That method solves a different requirement: a developer asks a coding assistant to generate dynamic SQL by interpolating an untrusted customer search string. The current case instead requires enable the supported Copilot experience under approved tenant settings and review proposed output before execution.

C:

AI-assisted tools may transmit inputs outside the data security perimeter, so input governance matters. That method solves a different requirement: a developer plans to paste production connection strings and customer rows into an external generative coding assistant to debug SQL. The current case instead requires enable the supported Copilot experience under approved tenant settings and review proposed output before execution.

D:

MCP server registration does not replace data plane permissions and source governance. That method solves a different requirement: a Fabric lakehouse MCP server offers data tools but a coding assistant must not query sensitive data outside the approved workspace. The current case instead requires enable the supported Copilot experience under approved tenant settings and review proposed output before execution.

Question 466

The database team applies the following decision: Enable the supported Copilot experience under approved tenant settings and review proposed output before execution. Given that an organization enables code assistance in Fabric notebooks and wants generated database statements to remain under least privilege. Which technical principle most directly explains why it works?

  1. An MCP server offers structured tools, while the connection policy determines what the assistant can access
  2. Tenant governance and human validation limit risky generated actions
  3. Checked-in instructions can provide shared persistent context beyond one chat session
  4. Tool visibility and database identities form separate layers of least-privilege control

Explanation

Correct Answer

B:

Tenant governance and human validation limit risky generated actions. This explains why the selected approach meets the requirement rather than merely changing a nearby service. A confirming observation is: assistive suggestions are available only to authorized users and deployment is reviewed.

Incorrect Answers

A:

An MCP server offers structured tools, while the connection policy determines what the assistant can access. That principle is applicable when a Copilot session must inspect schema metadata from a permitted SQL Server MCP endpoint with least privilege. It does not explain the selected change in the current case, which depends on tenant governance and human validation limit risky generated actions.

C:

Checked-in instructions can provide shared persistent context beyond one chat session. That principle is applicable when copilot repeatedly suggests unapproved naming and schema conventions after developers open new chat sessions. It does not explain the selected change in the current case, which depends on tenant governance and human validation limit risky generated actions.

D:

Tool visibility and database identities form separate layers of least-privilege control. That principle is applicable when an MCP tool can read production schema and execute writes, but the SQL developer only needs read-only planning support. It does not explain the selected change in the current case, which depends on tenant governance and human validation limit risky generated actions.

Question 467

The deployment validation team is assessing this proposal: Enable the supported Copilot experience under approved tenant settings and review proposed output before execution. The check must catch this potential failure: Enabling AI assistance is not permission to execute every generated SQL statement. Which observed outcome demonstrates the desired behavior?

  1. The assistant can explain a migration but cannot execute DDL without approval
  2. Security logs identify the principal and metadata-read operation
  3. Assistive suggestions are available only to authorized users and deployment is reviewed
  4. Suggestions align with naming and parameterization conventions during a test prompt

Explanation

Correct Answer

C:

Assistive suggestions are available only to authorized users and deployment is reviewed. This is the direct acceptance criterion because tenant governance and human validation limit risky generated actions. The validation should also distinguish the failure condition: enabling AI assistance is not permission to execute every generated SQL statement.

Incorrect Answers

A:

The assistant can explain a migration but cannot execute DDL without approval. That observation would validate a different requirement: a developer uses an AI-assisted SQL chat and needs to prevent the model from executing schema-changing operations without consent. Here the required evidence is assistive suggestions are available only to authorized users and deployment is reviewed.

That observation would validate a different requirement: a repository has conventions requiring parameterized queries, predictable object naming and no embedded secrets in generated SQL. Here the required evidence is assistive suggestions are available only to authorized users and deployment is reviewed.

Question 468

The reviewer rejects the current behavior: Enabling AI assistance is not permission to execute every generated SQL statement. The actual requirement is: An organization enables code assistance in Fabric notebooks and wants generated database statements to remain under least privilege. Which corrective implementation addresses the cause?

  1. Configure available model and tool permissions so schema-changing MCP operations require explicit authorization
  2. Configure an approved MCP connection with scoped database credentials and permitted tool calls
  3. Require parameterization and test AI-generated SQL against injection cases
  4. Enable the supported Copilot experience under approved tenant settings and review proposed output before execution

Explanation

Correct Answer

D:

Enable the supported Copilot experience under approved tenant settings and review proposed output before execution. Tenant governance and human validation limit risky generated actions. This directly corrects the observed failure, and success can be checked because assistive suggestions are available only to authorized users and deployment is reviewed.

Incorrect Answers

A:

Use the target remedy instead.

Question 469

A development review identifies this database requirement: An MCP tool can read production schema and execute writes, but the SQL developer only needs read-only planning support. Which implementation best satisfies this requirement?

  1. Select read-only MCP tools and enforce the underlying data source permissions
  2. Register only the approved server endpoint with workspace-scoped authorization and minimal accessible tools
  3. Remove secrets and sensitive customer data and use only an organization-approved AI assistance boundary
  4. Require parameterization and test AI-generated SQL against injection cases

Explanation

Correct Answer

A:

Tool visibility and database identities form separate layers of least-privilege control. For this stated production need, the recommended implementation is: Select read-only MCP tools and enforce the underlying data source permissions. Evidence to look for: schema discovery succeeds but a dml tool call is denied.

Incorrect Answers

B:

MCP server registration does not replace data plane permissions and source governance. That method solves a different requirement: a Fabric lakehouse MCP server offers data tools but a coding assistant must not query sensitive data outside the approved workspace. The current case instead requires select read-only MCP tools and enforce the underlying data source permissions.
