Question 370

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing solution architecture design during a localization review (MB820-1.2-015). The observed development issue is that an extension package references a library app but omits the required dependency from app.json. Which recurring engineering check would best prevent this issue from returning?

  1. Check AppSource compatibility and extension analyzer results before submission.
  2. Compare exported API surfaces at every version promotion.
  3. Audit app.json dependency lists during release packaging.
  4. Run translation coverage review before each AppSource release.

Explanation

Correct Answer

C:

The ongoing check is to audit app.json dependency lists during release packaging. This helps detect recurrence when an extension package references a library app but omits the required dependency from app.json. The associated correction is to declare the exact dependency identifier and compatible version constraints in the manifest; a confirming result is that compilation and installation resolve the prerequisite app before loading dependent objects.

Incorrect Answers

A:

“Check AppSource compatibility and extension analyzer results before submission” supports the separate task “implement published tables, page extensions and event subscribers rather than distributing a modified base application”, not the reported problem: an extension package references a library app but omits the required dependency from app.json. This case instead calls for “Audit app.json dependency lists during release packaging”.

B:

“Compare exported API surfaces at every version promotion” concerns the separate step “version public interfaces compatibly and review downstream dependency contracts before a breaking change”. The reported issue is that an extension package references a library app but omits the required dependency from app.json, so the direct response is to audit app.json dependency lists during release packaging.

D:

The proposed “Run translation coverage review before each AppSource release” tests a different control: add language translation files and validate translatable properties for the supported locales. The reported condition is that an extension package references a library app but omits the required dependency from app.json; the more direct action is to audit app.json dependency lists during release packaging.

Question 371

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing solution architecture design during a localization review (MB820-1.2-015). The observed development issue is that an extension package references a library app but omits the required dependency from app.json. Which Business Central or AL development principle best explains the right response?

  1. Business Central extension dependencies are explicit contracts.
  2. An extension's activation state is distinct from irreversible data deletion.
  3. Distribution scope and validation obligations depend on app type.
  4. Published extension interfaces are integration commitments.

Explanation

Correct Answer

A:

The governing principle is that business Central extension dependencies are explicit contracts. The engineering response is to declare the exact dependency identifier and compatible version constraints in the manifest. Verification should show that compilation and installation resolve the prerequisite app before loading dependent objects.

Incorrect Answers

B:

“An extension's activation state is distinct from irreversible data deletion” concerns the alternative task “document supported uninstall and delete-data behavior, preserve data as required and use deliberate cleanup procedures”, but the stated failure is that an extension package references a library app but omits the required dependency from app.json. The required measure is to declare the exact dependency identifier and compatible version constraints in the manifest.

C:

The proposed “Distribution scope and validation obligations depend on app type” tests a different control: select a per-tenant deployment for tenant-specific use and an AppSource publishing workflow for marketplace distribution. The reported condition is that an extension package references a library app but omits the required dependency from app.json; the more direct action is to declare the exact dependency identifier and compatible version constraints in the manifest.

D:

“Published extension interfaces are integration commitments” supports the separate task “version public interfaces compatibly and review downstream dependency contracts before a breaking change”, not the reported problem: an extension package references a library app but omits the required dependency from app.json. This case instead calls for “declare the exact dependency identifier and compatible version constraints in the manifest”.

Question 372

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing solution architecture design during a localization review (MB820-1.2-015). The observed development issue is that an extension package references a library app but omits the required dependency from app.json. Which observed result would most clearly show the intended correction works?

  1. Compilation and installation resolve the prerequisite app before loading dependent objects.
  2. After an app lifecycle test, retained data and removal actions match the documented policy.
  3. Shared workflows run with both apps installed and no conflicting state transitions.
  4. The combined installation completes without duplicate object ID errors.

Explanation

Correct Answer

A:

This is the outcome that directly verifies the intended correction: compilation and installation resolve the prerequisite app before loading dependent objects. The related solution is to declare the exact dependency identifier and compatible version constraints in the manifest; it is based on the principle that business Central extension dependencies are explicit contracts.

Incorrect Answers

B:

The proposed “After an app lifecycle test, retained data and removal actions match the documented policy” tests a different control: document supported uninstall and delete-data behavior, preserve data as required and use deliberate cleanup procedures. The reported condition is that an extension package references a library app but omits the required dependency from app.json; the more direct action is to compilation and installation resolve the prerequisite app before loading dependent objects.

C:

“Shared workflows run with both apps installed and no conflicting state transitions” supports the separate task “use documented extension points and define integration precedence, supported events and compatibility tests”, not the reported problem: an extension package references a library app but omits the required dependency from app.json. This case instead calls for “Compilation and installation resolve the prerequisite app before loading dependent objects”.

D:

“The combined installation completes without duplicate object ID errors” concerns the separate step “allocate supported object ID ranges and check unique app identity and object conflicts”. The reported issue is that an extension package references a library app but omits the required dependency from app.json, so the direct response is to compilation and installation resolve the prerequisite app before loading dependent objects.

Question 373

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing AL business logic and user experience during a source-control pull request (MB820-4.1-132). The observed development issue is that a tutorial points at an action that was moved by a page extension and can no longer be found. Which observed result would most clearly show the intended correction works?

  1. The service role opens a purpose-built navigation surface without affecting accounting users.
  2. The user opens the intended filtered record set with one selection.
  3. The guided tour locates the correct action in the target Role Center.
  4. Users understand the field's effect without learning AL implementation details.

Explanation

Correct Answer

C:

This is the outcome that directly verifies the intended correction: the guided tour locates the correct action in the target Role Center. The related solution is to update the teaching tip or in-app tour anchors to current page controls; it is based on the principle that contextual tours depend on actual UI structure.

Incorrect Answers

A:

The proposed “The service role opens a purpose-built navigation surface without affecting accounting users” tests a different control: create an AL profile tied to an appropriate Role Center and assign it to the intended users. The reported condition is that a tutorial points at an action that was moved by a page extension and can no longer be found; the more direct action is to the guided tour locates the correct action in the target Role Center.

B:

“The user opens the intended filtered record set with one selection” supports the separate task “provide a suitable list view or supported view customization for the role”, not the reported problem: a tutorial points at an action that was moved by a page extension and can no longer be found. This case instead calls for “The guided tour locates the correct action in the target Role Center”.

D:

“Users understand the field's effect without learning AL implementation details” concerns the alternative task “write clear supported tooltips and user assistance strings reflecting business meaning”, but the stated failure is that a tutorial points at an action that was moved by a page extension and can no longer be found. The required measure is to the guided tour locates the correct action in the target Role Center.

Question 374

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing AL business logic and user experience during a source-control pull request (MB820-4.1-132). The observed development issue is that a tutorial points at an action that was moved by a page extension and can no longer be found. Which Business Central or AL development principle best explains the right response?

  1. Contextual tours depend on actual UI structure.
  2. Checklists make first-run activities visible and actionable.
  3. Localization extends to onboarding content beyond standard fields.
  4. User assistance should explain outcomes rather than internals.

Explanation

Correct Answer

A:

The governing principle is that contextual tours depend on actual UI structure. The engineering response is to update the teaching tip or in-app tour anchors to current page controls. Verification should show that the guided tour locates the correct action in the target Role Center.

Incorrect Answers

B:

“Checklists make first-run activities visible and actionable” concerns the separate step “create an onboarding checklist with required tasks and suitable launch destinations”. The reported issue is that a tutorial points at an action that was moved by a page extension and can no longer be found, so the direct response is to update the teaching tip or in-app tour anchors to current page controls.

C:

“Localization extends to onboarding content beyond standard fields” concerns the alternative task “include user-assistance strings in the language resource review and translation workflow”, but the stated failure is that a tutorial points at an action that was moved by a page extension and can no longer be found. The required measure is to update the teaching tip or in-app tour anchors to current page controls.

D:

The proposed “User assistance should explain outcomes rather than internals” tests a different control: write clear supported tooltips and user assistance strings reflecting business meaning. The reported condition is that a tutorial points at an action that was moved by a page extension and can no longer be found; the more direct action is to update the teaching tip or in-app tour anchors to current page controls.

Question 375

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing AL business logic and user experience during a source-control pull request (MB820-4.1-132). The observed development issue is that a tutorial points at an action that was moved by a page extension and can no longer be found. Which recurring engineering check would best prevent this issue from returning?

  1. Review tooltips and teaching tips after workflow changes.
  2. Update checklist items when installation prerequisites change.
  3. Regression-test tours after page layout changes.
  4. Revalidate saved views when underlying fields are renamed.

Explanation

Correct Answer

C:

The ongoing check is to regression-test tours after page layout changes. This helps detect recurrence when a tutorial points at an action that was moved by a page extension and can no longer be found. The associated correction is to update the teaching tip or in-app tour anchors to current page controls; a confirming result is that the guided tour locates the correct action in the target Role Center.

Incorrect Answers

A:

“Review tooltips and teaching tips after workflow changes” concerns the separate step “add contextual user assistance or an appropriate teaching tip that explains the purpose and next step”. The reported issue is that a tutorial points at an action that was moved by a page extension and can no longer be found, so the direct response is to regression-test tours after page layout changes.

B:

“Update checklist items when installation prerequisites change” concerns the alternative task “create an onboarding checklist with required tasks and suitable launch destinations”, but the stated failure is that a tutorial points at an action that was moved by a page extension and can no longer be found. The required measure is to regression-test tours after page layout changes.

D:

“Revalidate saved views when underlying fields are renamed” supports the separate task “provide a suitable list view or supported view customization for the role”, not the reported problem: a tutorial points at an action that was moved by a page extension and can no longer be found. This case instead calls for “Regression-test tours after page layout changes”.

Question 376

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing AL business logic and user experience during a source-control pull request (MB820-4.1-132). The observed development issue is that a tutorial points at an action that was moved by a page extension and can no longer be found. Which AL development or design response most directly addresses this issue?

  1. Use an assisted setup flow with ordered steps, validation and completion state.
  2. Name and configure supported views clearly and test switching behavior.
  3. Update the teaching tip or in-app tour anchors to current page controls.
  4. Create an onboarding checklist with required tasks and suitable launch destinations.

Explanation

Correct Answer

C:

The most direct corrective response is to update the teaching tip or in-app tour anchors to current page controls. This addresses the specific failure where a tutorial points at an action that was moved by a page extension and can no longer be found. Acceptance evidence is that the guided tour locates the correct action in the target Role Center.

Incorrect Answers

A:

“Use an assisted setup flow with ordered steps, validation and completion state” concerns the alternative task “use an assisted setup flow with ordered steps, validation and completion state”, but the stated failure is that a tutorial points at an action that was moved by a page extension and can no longer be found. The required measure is to update the teaching tip or in-app tour anchors to current page controls.

B:

The proposed “Name and configure supported views clearly and test switching behavior” tests a different control: name and configure supported views clearly and test switching behavior. The reported condition is that a tutorial points at an action that was moved by a page extension and can no longer be found; the more direct action is to update the teaching tip or in-app tour anchors to current page controls.

D:

“Create an onboarding checklist with required tasks and suitable launch destinations” concerns the separate step “create an onboarding checklist with required tasks and suitable launch destinations”. The reported issue is that a tutorial points at an action that was moved by a page extension and can no longer be found, so the direct response is to update the teaching tip or in-app tour anchors to current page controls.

Question 377

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing object model and application extensibility during a tenant acceptance test (MB820-3.5-112). The observed development issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. Which AL development or design response most directly addresses this issue?

  1. Add the table-data rights to an appropriate permissionset or permissionsetextension.
  2. Enforce access using resource-side permission sets and protected code paths.
  3. Use documented permissions properties or least-privilege execution design where applicable.
  4. Trim permissions to the exact object set and operations required for business tasks.

Explanation

Correct Answer

C:

The most direct corrective response is to use documented permissions properties or least-privilege execution design where applicable. This addresses the specific failure where a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. Acceptance evidence is that the codeunit performs only its approved operation without giving every caller broad table rights.

Incorrect Answers

A:

The proposed “Add the table-data rights to an appropriate permissionset or permissionsetextension” tests a different control: add the table-data rights to an appropriate permissionset or permissionsetextension. The reported condition is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow; the more direct action is to use documented permissions properties or least-privilege execution design where applicable.

B:

“Enforce access using resource-side permission sets and protected code paths” supports the separate task “enforce access using resource-side permission sets and protected code paths”, not the reported problem: a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. This case instead calls for “use documented permissions properties or least-privilege execution design where applicable”.

D:

“Trim permissions to the exact object set and operations required for business tasks” concerns the alternative task “trim permissions to the exact object set and operations required for business tasks”, but the stated failure is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. The required measure is to use documented permissions properties or least-privilege execution design where applicable.

Question 378

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing object model and application extensibility during a tenant acceptance test (MB820-3.5-112). The observed development issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. Which Business Central or AL development principle best explains the right response?

  1. Least privilege limits blast radius from extensibility flaws.
  2. UI visibility is not a security boundary.
  3. Composite permissions may be broader than an individual set suggests.
  4. Elevated execution must be deliberately scoped and reviewed.

Explanation

Correct Answer

D:

The governing principle is that elevated execution must be deliberately scoped and reviewed. The engineering response is to use documented permissions properties or least-privilege execution design where applicable. Verification should show that the codeunit performs only its approved operation without giving every caller broad table rights.

Incorrect Answers

A:

“Least privilege limits blast radius from extensibility flaws” supports the separate task “trim permissions to the exact object set and operations required for business tasks”, not the reported problem: a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. This case instead calls for “use documented permissions properties or least-privilege execution design where applicable”.

B:

“UI visibility is not a security boundary” concerns the separate step “enforce access using resource-side permission sets and protected code paths”. The reported issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow, so the direct response is to use documented permissions properties or least-privilege execution design where applicable.

C:

“Composite permissions may be broader than an individual set suggests” concerns the alternative task “inspect effective permissions and role composition, then remove or constrain excessive assignments”, but the stated failure is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. The required measure is to use documented permissions properties or least-privilege execution design where applicable.

Question 379

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing object model and application extensibility during a tenant acceptance test (MB820-3.5-112). The observed development issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. Which recurring engineering check would best prevent this issue from returning?

  1. Review entitlement-to-role effects when product packaging changes.
  2. Compare effective role grants before each release.
  3. Audit privileged codeunit entry points.
  4. Check permission drift with every new object declaration.

Explanation

Correct Answer

C:

The ongoing check is to audit privileged codeunit entry points. This helps detect recurrence when a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. The associated correction is to use documented permissions properties or least-privilege execution design where applicable; a confirming result is that the codeunit performs only its approved operation without giving every caller broad table rights.

Incorrect Answers

A:

“Review entitlement-to-role effects when product packaging changes” concerns the separate step “model supported entitlements and application rights separately, testing their combined effect”. The reported issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow, so the direct response is to audit privileged codeunit entry points.

B:

“Compare effective role grants before each release” concerns the alternative task “trim permissions to the exact object set and operations required for business tasks”, but the stated failure is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. The required measure is to audit privileged codeunit entry points.

D:

“Check permission drift with every new object declaration” supports the separate task “add the table-data rights to an appropriate permissionset or permissionsetextension”, not the reported problem: a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. This case instead calls for “Audit privileged codeunit entry points”.

Question 380

At fictional Granite Telecom, the Business Central development team is supporting field equipment billing and reviewing object model and application extensibility during a tenant acceptance test (MB820-3.5-112). The observed development issue is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. Which observed result would most clearly show the intended correction works?

  1. Authorized users can perform required operations on the new table only.
  2. Read succeeds and an attempted unauthorized write is denied.
  3. The codeunit performs only its approved operation without giving every caller broad table rights.
  4. Users with the intended license retain approved features while restricted capabilities remain unavailable.

Explanation

Correct Answer

C:

This is the outcome that directly verifies the intended correction: the codeunit performs only its approved operation without giving every caller broad table rights. The related solution is to use documented permissions properties or least-privilege execution design where applicable; it is based on the principle that elevated execution must be deliberately scoped and reviewed.

Incorrect Answers

A:

“Authorized users can perform required operations on the new table only” concerns the alternative task “add the table-data rights to an appropriate permissionset or permissionsetextension”, but the stated failure is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow. The required measure is to the codeunit performs only its approved operation without giving every caller broad table rights.

B:

The proposed “Read succeeds and an attempted unauthorized write is denied” tests a different control: assign a role with read rights and no unauthorized edit permissions to the relevant table data. The reported condition is that a finance extension requires a service codeunit to update a protected table on behalf of a controlled workflow; the more direct action is to the codeunit performs only its approved operation without giving every caller broad table rights.

D:

“Users with the intended license retain approved features while restricted capabilities remain unavailable” concerns the separate step “model supported entitlements and application rights separately, testing their combined effect”.
