Question 550

A data engineer needs to modify model measures, but someone grants only Build permission. What is missing?

  1. Grant appropriate write/collaboration rights for model modification.
  2. Grant supported Build permission on the semantic model.
  3. Use appropriately governed report sharing to that group.
  4. Use a curated Power BI app with appropriate audiences.

Explanation

Correct Answer

A:

Grant appropriate write/collaboration rights for model modification. Build authorizes report creation from a model, not editing its definition.

Incorrect Answers

B:

Build allows creation of dependent reports without assigning workspace contributor rights. The boundary it addresses is “semantic model but not edit its data definition”, while this case concerns “model measures, but someone grants only Build permission”.

C:

Direct sharing can distribute an individual report to designated readers. This solves “approved group instead of the whole app catalog”; the stated issue is “model measures, but someone grants only Build permission”.

D:

Apps are designed for organized broad report consumption. The deciding difference is “distributes many related reports to thousands of employees” versus “model measures, but someone grants only Build permission”.

Question 551

A workspace has no documented owner for scheduled refresh failures. What operational practice is needed?

  1. Maintain change history and review records for governed reporting assets.
  2. Transfer or document item ownership, credentials and gateway responsibilities.
  3. Assign explicit semantic-model refresh ownership and support responsibility.
  4. Use approval and deployment checks before promoting content to production audiences.

Explanation

Correct Answer

C:

Assign explicit semantic-model refresh ownership and support responsibility. Named ownership enables timely investigation and recovery.

Incorrect Answers

A:

Maintain change history and review records for governed reporting assets. The deciding difference is “is modified without recording who approved the change” versus “has no documented owner for scheduled refresh failures”.

B:

Continuity planning prevents abandoned refresh and access dependencies. Its application is “on a model maintained by one departing employee”, not the need “has no documented owner for scheduled refresh failures”.

D:

Release gates reduce accidental exposure of unverified reports. It serves “with experimental DAX measures to the production app”, not “has no documented owner for scheduled refresh failures”.

Question 552

A critical finance app depends on a model maintained by one departing employee. What should be planned?

  1. Transfer or document item ownership, credentials and gateway responsibilities.
  2. Review workspace lineage and data-source dependencies.
  3. Assign explicit semantic-model refresh ownership and support responsibility.
  4. Use approval and deployment checks before promoting content to production audiences.

Explanation

Correct Answer

A:

Transfer or document item ownership, credentials and gateway responsibilities. Continuity planning prevents abandoned refresh and access dependencies.

Incorrect Answers

B:

Lineage views can expose upstream and downstream item relationships. The present requirement is “on a model maintained by one departing employee”; “model's data lineage is unclear across several reports” is a distinct situation.

C:

Named ownership enables timely investigation and recovery. That matters for “has no documented owner for scheduled refresh failures” rather than the condition “on a model maintained by one departing employee”.

D:

Release gates reduce accidental exposure of unverified reports. The boundary it addresses is “with experimental DAX measures to the production app”, while this case concerns “on a model maintained by one departing employee”.

Question 553

A team accidentally publishes a draft report with experimental DAX measures to the production app. What governance improvement helps?

  1. Assign explicit semantic-model refresh ownership and support responsibility.
  2. Review workspace lineage and data-source dependencies.
  3. Transfer or document item ownership, credentials and gateway responsibilities.
  4. Use approval and deployment checks before promoting content to production audiences.

Explanation

Correct Answer

D:

Use approval and deployment checks before promoting content to production audiences. Release gates reduce accidental exposure of unverified reports.

Incorrect Answers

A:

Named ownership enables timely investigation and recovery. The boundary it addresses is “has no documented owner for scheduled refresh failures”, while this case concerns “with experimental DAX measures to the production app”.

B:

Lineage views can expose upstream and downstream item relationships. This solves “model's data lineage is unclear across several reports”; the stated issue is “with experimental DAX measures to the production app”.

C:

Continuity planning prevents abandoned refresh and access dependencies. The deciding difference is “on a model maintained by one departing employee” versus “with experimental DAX measures to the production app”.

Question 554

A source semantic model's data lineage is unclear across several reports. What should be examined?

  1. Maintain change history and review records for governed reporting assets.
  2. Assign explicit semantic-model refresh ownership and support responsibility.
  3. Review workspace lineage and data-source dependencies.
  4. Use approval and deployment checks before promoting content to production audiences.

Explanation

Correct Answer

C:

Review workspace lineage and data-source dependencies. Lineage views can expose upstream and downstream item relationships.

Incorrect Answers

A:

Maintain change history and review records for governed reporting assets. Its application is “is modified without recording who approved the change”, not the need “model's data lineage is unclear across several reports”.

B:

Named ownership enables timely investigation and recovery. That is a different operating condition from “model's data lineage is unclear across several reports”: “has no documented owner for scheduled refresh failures”.

D:

Release gates reduce accidental exposure of unverified reports. The present requirement is “model's data lineage is unclear across several reports”; “with experimental DAX measures to the production app” is a distinct situation.

Question 555

A shared report is modified without recording who approved the change. What process helps?

  1. Review workspace lineage and data-source dependencies.
  2. Assign explicit semantic-model refresh ownership and support responsibility.
  3. Maintain change history and review records for governed reporting assets.
  4. Transfer or document item ownership, credentials and gateway responsibilities.

Explanation

Correct Answer

C:

Maintain change history and review records for governed reporting assets. Auditability connects releases to accountable decisions.

Incorrect Answers

A:

Lineage views can expose upstream and downstream item relationships. The present requirement is “is modified without recording who approved the change”; “model's data lineage is unclear across several reports” is a distinct situation.

B:

Named ownership enables timely investigation and recovery. That matters for “has no documented owner for scheduled refresh failures” rather than the condition “is modified without recording who approved the change”.

D:

Continuity planning prevents abandoned refresh and access dependencies. This solves “on a model maintained by one departing employee”; the stated issue is “is modified without recording who approved the change”.

Question 556

A Sales semantic model must show each regional sales team only its assigned fixed Region rows. What modeling control fits?

  1. Create an RLS role with a Region filter expression on the appropriate table.
  2. Store multiple authorized user-to-region mappings where business policy permits.
  3. Use USERPRINCIPALNAME in a dynamic RLS mapping expression.
  4. Enforce regional restrictions with RLS rather than only report filters.

Explanation

Correct Answer

A:

Create an RLS role with a Region filter expression on the appropriate table. Row-level security filters semantic-model records for members of the role.

Incorrect Answers

B:

A mapping table can represent one user with several allowed data scopes. The deciding difference is “rows from two Region assignments, not only one” versus “sales team only its assigned fixed Region rows”.

C:

User identity can map to allowed rows in a security table. Its application is “regional employees dynamically based on their sign-in identity”, not the need “sales team only its assigned fixed Region rows”.

D:

Visual and report filters are navigation aids, not security controls. That is a different operating condition from “sales team only its assigned fixed Region rows”: “users cannot remove it to see other rows”.

Question 557

A single role should filter different regional employees dynamically based on their sign-in identity. What DAX function helps?

  1. Relate UserAccess to the governed dimension and filter it by current user identity.
  2. Create an RLS role with a Region filter expression on the appropriate table.
  3. Enforce regional restrictions with RLS rather than only report filters.
  4. Use USERPRINCIPALNAME in a dynamic RLS mapping expression.

Explanation

Correct Answer

D:

Use USERPRINCIPALNAME in a dynamic RLS mapping expression. User identity can map to allowed rows in a security table.

Incorrect Answers

A:

Identity-to-entity mappings allow model security to restrict related facts. That is a different operating condition from “regional employees dynamically based on their sign-in identity”: “a UserAccess table mapping users to allowed StoreIDs”.

B:

Row-level security filters semantic-model records for members of the role. It serves “sales team only its assigned fixed Region rows”, not “regional employees dynamically based on their sign-in identity”.

C:

Visual and report filters are navigation aids, not security controls. The present requirement is “regional employees dynamically based on their sign-in identity”; “users cannot remove it to see other rows” is a distinct situation.

Question 558

A report author sets a visual Region filter and assumes users cannot remove it to see other rows. What is wrong?

  1. Use USERPRINCIPALNAME in a dynamic RLS mapping expression.
  2. Relate UserAccess to the governed dimension and filter it by current user identity.
  3. Enforce regional restrictions with RLS rather than only report filters.
  4. Create an RLS role with a Region filter expression on the appropriate table.

Explanation

Correct Answer

C:

Enforce regional restrictions with RLS rather than only report filters. Visual and report filters are navigation aids, not security controls.

Incorrect Answers

A:

User identity can map to allowed rows in a security table. That matters for “regional employees dynamically based on their sign-in identity” rather than the condition “users cannot remove it to see other rows”.

B:

Identity-to-entity mappings allow model security to restrict related facts. The boundary it addresses is “a UserAccess table mapping users to allowed StoreIDs”, while this case concerns “users cannot remove it to see other rows”.

D:

Row-level security filters semantic-model records for members of the role. The deciding difference is “sales team only its assigned fixed Region rows” versus “users cannot remove it to see other rows”.

Question 559

A semantic model contains a UserAccess table mapping users to allowed StoreIDs. What design supports dynamic RLS?

  1. Use USERPRINCIPALNAME in a dynamic RLS mapping expression.
  2. Create an RLS role with a Region filter expression on the appropriate table.
  3. Enforce regional restrictions with RLS rather than only report filters.
  4. Relate UserAccess to the governed dimension and filter it by current user identity.

Explanation

Correct Answer

D:

Relate UserAccess to the governed dimension and filter it by current user identity. Identity-to-entity mappings allow model security to restrict related facts.

Incorrect Answers

A:

User identity can map to allowed rows in a security table. The deciding difference is “regional employees dynamically based on their sign-in identity” versus “a UserAccess table mapping users to allowed StoreIDs”.

B:

C:

Visual and report filters are navigation aids, not security controls. That is a different operating condition from “a UserAccess table mapping users to allowed StoreIDs”: “users cannot remove it to see other rows”.

Question 560

An RLS role grants a user rows from two Region assignments, not only one. How should membership be represented?

  1. Create an RLS role with a Region filter expression on the appropriate table.
  2. Enforce regional restrictions with RLS rather than only report filters.
  3. Store multiple authorized user-to-region mappings where business policy permits.
  4. Relate UserAccess to the governed dimension and filter it by current user identity.

Explanation

Correct Answer

C:

Store multiple authorized user-to-region mappings where business policy permits. A mapping table can represent one user with several allowed data scopes.

Incorrect Answers

A:
