Microsoft PL-300 Practice Test 79

Question 780

A data source enforces read-only query access, but the gateway identity was configured with database administrator rights. Which implementation best addresses this scenario?

  1. Reinstate approved network segmentation and connection allowlists.
  2. Replace the personal credentials with an approved service-owned connection identity.
  3. Deny credential disclosure and manage gateway permissions through scoped roles.
  4. Restrict the gateway connection to least-privileged read permissions.

Explanation

Correct Answer

D:

Minimal source privileges reduce risk of refresh credential compromise; this helps prevent overprivileged refresh source access.

Incorrect Answers

A:

Network controls restrict private-source access beyond semantic model roles. It would address defend private data source connectivity, not prevent overprivileged refresh source access.

B:

Managed source identities improve continuity and reduce orphaned credentials. That targets accountable gateway credential ownership, not prevent overprivileged refresh source access.

C:

Gateway credential secrets are not ordinary report-consumption data. It may suit protect data source secrets from readers, not prevent overprivileged refresh source access.

Question 781

A report designer wants to distribute one approved report to external customers while preserving their identity isolation. What is the best method for this analysis requirement?

  1. Use an appropriate authenticated embedded/customer architecture with supported authorization.
  2. Review and configure tenant Power BI settings for workspace creation and external sharing.
  3. Apply an appropriate tenant-level Publish to web restriction.
  4. Configure supported tenant and report export settings for allowed groups.

Explanation

Correct Answer

A:

Customer embedding needs a deliberate security model; anonymous embeds are not adequate, supporting governed customer-facing analytics delivery.

Incorrect Answers

B:

Tenant-wide policies constrain administrative features and distribution capabilities. Its scope is centrally govern workspace and sharing features, not governed customer-facing analytics delivery.

C:

Tenant settings govern availability of public embedding features. That is meant for prevent anonymous report publication, not governed customer-facing analytics delivery.

D:

Export governance controls permitted extraction operations. It would address restrict sensitive underlying data export, not governed customer-facing analytics delivery.

Question 782

A report author is workspace Admin but the RLS Preview appears restricted in Desktop, causing confusion about service behavior. Which implementation best addresses this scenario?

  1. Validate security mapping keys and the viewer's effective identity.
  2. Test with an actual Viewer or appropriate role instead of inferring Admin restrictions.
  3. Review additive role membership and design a single intended entitlement mapping if necessary.
  4. Use View as role and validate the matching published test account.

Explanation

Correct Answer

B:

Elevated workspace roles may bypass service RLS even if Desktop simulates a role, supporting accurate production consumer security test.

Incorrect Answers

A:

Dynamic access requires exact identity-to-entitlement matching. It would address diagnose missing dynamic RLS rows, not accurate production consumer security test.

C:

Multiple RLS roles may combine accessible row sets. It may suit prevent role-union overexposure, not accurate production consumer security test.

D:

Testing under intended role context reveals unintended row exposure. It is useful for validating static region RLS behavior, not for accurate production consumer security test.

Question 783

A corporate portal must embed a report and enforce the signed-in employee's Power BI identity and RLS. What is the best method for this analysis requirement?

  1. Share via authenticated Power BI app or report item permissions.
  2. Consider Publish to web only if the entire content is approved for anonymous access.
  3. Use appropriate Embed for your organization with delegated user authorization.
  4. Design an approved Embed for your customers architecture and effective identity/RLS enforcement.

Explanation

Correct Answer

C:

Internal embedding preserves an authenticated user security context, supporting employee-scoped intranet Power BI embedding.

Incorrect Answers

A:

Identity-aware distribution enforces continuing entitlement checks. It is useful for ongoing private board report access, not for employee-scoped intranet Power BI embedding.

B:

Public embedding exposes the report to anyone with the address. Its scope is intentionally anonymous public summary, not employee-scoped intranet Power BI embedding.

D:

Customer embedding requires an explicit backend authorization design rather than trusting public links. It would address multi-tenant embedded customer isolation, not employee-scoped intranet Power BI embedding.

Question 784

A finance report is Confidential and authorized exports should carry the classification. Which implementation best addresses this scenario?

  1. Assign workspace roles according to least privilege.
  2. Implement regional RLS roles and assign intended users.
  3. Apply supported object-level security to restricted columns.
  4. Apply a supported sensitivity label with appropriate protection and export behavior.

Explanation

Correct Answer

D:

Labels classify content independently of row and object permissions, supporting label-based content classification and export.

Incorrect Answers

A:

Workspace RBAC controls item authoring and administration, not row visibility. It would address limit report editing privileges, not label-based content classification and export.

B:

RLS restricts rows while retaining columns. That targets region-level record authorization, not label-based content classification and export.

C:

OLS hides sensitive model fields beyond ordinary row filtering. It may suit conceal HR-confidential columns, not label-based content classification and export.

Question 785

A user needs the same sales data as peers without any regional restriction. What is the best method for this analysis requirement?

  1. Create distinct static RLS roles and assign authorized users to each.
  2. Grant access consistent with an unrestricted authorized data role, not an artificial region-specific role.
  3. Create an RLS role with an East-region filter on the relevant dimension.
  4. Define a South-district RLS filter on the dimension with valid relationship propagation.

Explanation

Correct Answer

B:

RLS design should reflect actual approved data entitlement, supporting authorized complete-sales visibility.

Incorrect Answers

A:

Static roles apply predetermined filter expressions based on assigned membership. It is useful for fixed per-region security cohorts, not for authorized complete-sales visibility.

C:

Static RLS filters eligible model rows for users assigned to that role. That is meant for restrict one regional team's facts, not authorized complete-sales visibility.

D:

Dimension-scoped security can filter related fact records when the model path supports it. It would address enforce district-specific row visibility, not authorized complete-sales visibility.

Question 786

A report designer places a fixed "East" filter in a report slicer to emulate per-user access. Which implementation best addresses this scenario?

  1. Model security membership bridge and filter through verified relationships.
  2. Reconcile UPN mappings in the security table and test effective identities.
  3. Implement semantic-model RLS rather than relying on a removable slicer.
  4. Implement dynamic RLS using USERPRINCIPALNAME and a validated manager access table.

Explanation

Correct Answer

C:

Report filters are presentation controls, not authorization boundaries; this helps enforce security beyond slicer selections.

Incorrect Answers

A:

Membership mapping handles many permitted values per user without hard-coded filters. It would address variable multi-center row security, not enforce security beyond slicer selections.

B:

Dynamic RLS depends on exact identity resolution to the permitted mapping. That targets fix changed viewer identity matches, not enforce security beyond slicer selections.

D:

Dynamic security maps the viewing identity to current permitted customer rows. It is useful for identity-driven customer entitlements, not for enforcing security beyond slicer selections.

Question 787

Several groups overlap in multiple RLS roles and users see a union of data, not an intended intersection. What is the best method for this analysis requirement?

  1. Assign the security group to the semantic model's RLS role.
  2. Assign published users to service RLS roles and verify effective access.
  3. Remove their authorized mapping row and validate downstream access.
  4. Review multi-role membership and redesign role assignments for required restrictions.

Explanation

Correct Answer

D:

Power BI RLS filters can be additive across roles rather than combining as an intersection; this helps prevent unintended expansion from multiple roles.

Incorrect Answers

A:

RLS role membership determines whose queries receive the corresponding filters. It is useful for activate role security for approved group, not for preventing unintended expansion from multiple roles.

B:

Desktop role testing does not itself enroll service principals or users in a role. Its scope is enforce RLS in published model, not prevent unintended expansion from multiple roles.

C:

Security mappings should follow lifecycle changes to avoid stale row entitlements. That is meant for revoke row access after contractor end, not prevent unintended expansion from multiple roles.

Question 788

A report must let a designer edit a model yet not expose confidential HR rows. Which implementation best addresses this scenario?

  1. Separate protected HR data into an appropriately secured model or workspace rather than relying on RLS alone for editors.
  2. Grant an appropriate Viewer or app consumption permission with RLS role assignment.
  3. Test as the target role with View As and verified service user identities.
  4. Remove the elevated authoring role and grant suitable read-only access.

Explanation

Correct Answer

A:

Privileged model roles are not constrained by ordinary consumer RLS; this helps protect sensitive data from model authors.

Incorrect Answers

B:

RLS is enforced for eligible consumers rather than privileged workspace editors. That targets preserve RLS for ordinary report consumer, not protect sensitive data from model authors.

C:

Edit-capable workspace roles are not reliable proxies for restricted Viewer experience. It may suit accurately test viewer RLS, not protect sensitive data from model authors.

D:

Admin, Member and Contributor roles can bypass RLS filtering on items they can edit. It is useful for avoiding RLS bypass through author privilege, not for protecting sensitive data from model authors.

Question 789

A team needs to audit who can create new reports against a confidential model. What is the best method for this analysis requirement?

  1. Restrict Build permission to explicitly authorized author groups.
  2. Review semantic model permission assignments, including Build recipients.
  3. Grant eligible Build permission on the semantic model.
  4. Grant Read or app viewer access without unnecessary Build permission.

Explanation

Correct Answer

B:

Build permission inventory identifies allowed downstream authors, supporting enumerate authorized model builders.

Incorrect Answers

A:

Model Build can enable additional content creation and exploration beyond simple viewing. It is useful for limiting downstream data modeling access, not for enumerate authorized model builders.

C:

Build permission allows authorized users to create related content from the model. That is meant for authorized shared model report creation, not enumerate authorized model builders.

D:

Consumption generally needs less privilege than report authoring. It would address read-only report consumption privilege, not enumerate authorized model builders.

Question 790

A report user's app audience is correct but its shared semantic model access is missing. Which implementation best addresses this scenario?

  1. Configure separate app audiences with appropriate item visibility.
  2. Keep effective permissions restricted and rely on authorization checks instead of link secrecy.
  3. Grant the minimum applicable semantic model rights required for app consumption.
  4. Enforce data authorization through semantic model permissions and RLS, not app visibility alone.

Explanation

Correct Answer

C:

Underlying item authorization remains relevant to report use; this helps resolve underlying model access dependency.

Incorrect Answers

A:

Audiences tailor which reports are delivered without unnecessarily duplicating a model. It would address department-specific app content, not resolve underlying model access dependency.

B:

URLs do not themselves grant underlying report access when governed correctly. That targets prevent access from forwarded app link, not resolve underlying model access dependency.

D:

App audiences control content navigation, not every possible underlying model access path. It is useful for protecting data beyond app audience display, not for resolving underlying model access dependency.
