Question 790

At fictional Valley Media, the Business Central development team is supporting advertising orders and invoices and reviewing object model and application extensibility during an extension maintenance sprint (MB820-3.5-106). The observed development issue is that a report extension fails under a user account although it works with SUPER permission. Which Business Central or AL development principle best explains the right response?

  1. Composite permissions may be broader than an individual set suggests.
  2. Administrative privileges mask missing application permissions.
  3. Elevated execution must be deliberately scoped and reviewed.
  4. Object execution and data permissions are separate requirements.

Explanation

Correct Answer

B:

The governing principle is that administrative privileges mask missing application permissions. The engineering response is to identify required object/table permissions and provide the narrowest supported permission set. Verification should show that the report runs under the intended role without granting SUPER.

Incorrect Answers

A:

“Composite permissions may be broader than an individual set suggests” supports the separate task “inspect effective permissions and role composition, then remove or constrain excessive assignments”, not the reported problem: a report extension fails under a user account although it works with SUPER permission. This case instead calls for “identify required object/table permissions and provide the narrowest supported permission set”.

C:

“Elevated execution must be deliberately scoped and reviewed” concerns the alternative task “use documented permissions properties or least-privilege execution design where applicable”, but the stated failure is that a report extension fails under a user account although it works with SUPER permission. The required measure is to identify required object/table permissions and provide the narrowest supported permission set.

D:

The proposed “Object execution and data permissions are separate requirements” tests a different control: include appropriate page execution permissions and necessary underlying table-data rights. The reported condition is that a report extension fails under a user account although it works with SUPER permission; the more direct action is to identify required object/table permissions and provide the narrowest supported permission set.

Question 791

At fictional Valley Media, the Business Central development team is supporting advertising orders and invoices and reviewing object model and application extensibility during an extension maintenance sprint (MB820-3.5-106). The observed development issue is that a report extension fails under a user account although it works with SUPER permission. Which AL development or design response most directly addresses this issue?

  1. Model supported entitlements and application rights separately, testing their combined effect.
  2. Add the table-data rights to an appropriate permissionset or permissionsetextension.
  3. Assign a role with read rights and no unauthorized edit permissions to the relevant table data.
  4. Identify required object/table permissions and provide the narrowest supported permission set.

Explanation

Correct Answer

D:

The most direct corrective response is to identify required object/table permissions and provide the narrowest supported permission set. This addresses the specific failure where a report extension fails under a user account although it works with SUPER permission. Acceptance evidence is that the report runs under the intended role without granting SUPER.

Incorrect Answers

A:

“Model supported entitlements and application rights separately, testing their combined effect” concerns the separate step “model supported entitlements and application rights separately, testing their combined effect”. The reported issue is that a report extension fails under a user account although it works with SUPER permission, so the direct response is to identify required object/table permissions and provide the narrowest supported permission set.

B:

“Add the table-data rights to an appropriate permissionset or permissionsetextension” concerns the alternative task “add the table-data rights to an appropriate permissionset or permissionsetextension”, but the stated failure is that a report extension fails under a user account although it works with SUPER permission. The required measure is to identify required object/table permissions and provide the narrowest supported permission set.

C:

The proposed “Assign a role with read rights and no unauthorized edit permissions to the relevant table data” 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 report extension fails under a user account although it works with SUPER permission; the more direct action is to identify required object/table permissions and provide the narrowest supported permission set.

Question 792

At fictional Valley Media, the Business Central development team is supporting advertising orders and invoices and reviewing object model and application extensibility during an extension maintenance sprint (MB820-3.5-106). The observed development issue is that a report extension fails under a user account although it works with SUPER permission. Which observed result would most clearly show the intended correction works?

  1. An unauthorized API call fails even when the UI action is hidden.
  2. Read succeeds and an attempted unauthorized write is denied.
  3. Authorized users can perform required operations on the new table only.
  4. The report runs under the intended role without granting SUPER.

Explanation

Correct Answer

D:

This is the outcome that directly verifies the intended correction: the report runs under the intended role without granting SUPER. The related solution is to identify required object/table permissions and provide the narrowest supported permission set; it is based on the principle that administrative privileges mask missing application permissions.

Incorrect Answers

A:

“An unauthorized API call fails even when the UI action is hidden” concerns the alternative task “enforce access using resource-side permission sets and protected code paths”, but the stated failure is that a report extension fails under a user account although it works with SUPER permission. The required measure is to the report runs under the intended role without granting SUPER.

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 report extension fails under a user account although it works with SUPER permission; the more direct action is to the report runs under the intended role without granting SUPER.

C:

“Authorized users can perform required operations on the new table only” supports the separate task “add the table-data rights to an appropriate permissionset or permissionsetextension”, not the reported problem: a report extension fails under a user account although it works with SUPER permission. This case instead calls for “The report runs under the intended role without granting SUPER”.

Question 793

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing extension environment and deployment preparation during an AL developer handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. Which AL development or design response most directly addresses this issue?

  1. Publish and install compatible dependencies before the dependent .app file.
  2. Promote a versioned extension artifact through sandbox acceptance before production deployment.
  3. Review compile or analyzer compatibility warnings and update the extension in a sandbox before installing the new version.
  4. Use AL labels and language translation resources rather than embedding UI messages as literals.

Explanation

Correct Answer

A:

The most direct corrective response is to publish and install compatible dependencies before the dependent .app file. This addresses the specific failure where an app compiles but fails installation because a dependent extension has not been installed. Acceptance evidence is that the extension installs after prerequisites are present and the dependency graph resolves. Applied here, the relevant facts are: handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. The question asks which AL development or design response most directly addresses this issue.

Incorrect Answers

B:

“Promote a versioned extension artifact through sandbox acceptance before production deployment” supports the separate task “promote a versioned extension artifact through sandbox acceptance before production deployment”, not the reported problem: an app compiles but fails installation because a dependent extension has not been installed. This case instead calls for “publish and install compatible dependencies before the dependent”.

C:

“Review compile or analyzer compatibility warnings and update the extension in a sandbox before installing the new version” concerns the separate step “review compile or analyzer compatibility warnings and update the extension in a sandbox before installing the new version”. The reported issue is that an app compiles but fails installation because a dependent extension has not been installed, so the direct response is to publish and install compatible dependencies before the dependent.

D:

“Use AL labels and language translation resources rather than embedding UI messages as literals” concerns the alternative task “use AL labels and language translation resources rather than embedding UI messages as literals”, but the stated failure is that an app compiles but fails installation because a dependent extension has not been installed. The required measure is to publish and install compatible dependencies before the dependent.

Question 794

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing extension environment and deployment preparation during an AL developer handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. Which recurring engineering check would best prevent this issue from returning?

  1. Verify dependency status in deployment pipeline gates.
  2. Gate completion on installed version and smoke-test results.
  3. Run data migration regression tests with representative historical records.
  4. Compare package version metadata against deployment records.

Explanation

Correct Answer

A:

The ongoing check is to verify dependency status in deployment pipeline gates. This helps detect recurrence when an app compiles but fails installation because a dependent extension has not been installed. The associated correction is to publish and install compatible dependencies before the dependent .app file; a confirming result is that the extension installs after prerequisites are present and the dependency graph resolves. Applied here, the relevant facts are: handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. The question asks which recurring engineering check would best prevent this issue from returning.

Incorrect Answers

B:

“Gate completion on installed version and smoke-test results” concerns the separate step “separate publish, synchronize, install or upgrade and validation stages with explicit failure reporting”. The reported issue is that an app compiles but fails installation because a dependent extension has not been installed, so the direct response is to verify dependency status in deployment pipeline gates.

C:

“Run data migration regression tests with representative historical records” concerns the alternative task “use a versioned upgrade codeunit and preserve/migrate existing records before using the new schema”, but the stated failure is that an app compiles but fails installation because a dependent extension has not been installed. The required measure is to verify dependency status in deployment pipeline gates.

D:

The proposed “Compare package version metadata against deployment records” tests a different control: increment the extension version and follow the supported package publish/upgrade path. The reported condition is that an app compiles but fails installation because a dependent extension has not been installed; the more direct action is to verify dependency status in deployment pipeline gates.

Question 795

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing extension environment and deployment preparation during an AL developer handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. Which Business Central or AL development principle best explains the right response?

  1. Debugging does not constitute an extension rollback mechanism.
  2. User-facing text belongs in localizable resources.
  3. Controlled deployment should promote tested artifacts rather than unverified rebuilds.
  4. Build success does not guarantee extension installation prerequisites.

Explanation

Correct Answer

D:

The governing principle is that build success does not guarantee extension installation prerequisites. The engineering response is to publish and install compatible dependencies before the dependent .app file. Verification should show that the extension installs after prerequisites are present and the dependency graph resolves. Applied here, the relevant facts are: handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. The question asks which Business Central or AL development principle best explains the right response.

Incorrect Answers

A:

“Debugging does not constitute an extension rollback mechanism” concerns the separate step “separate debugger lifecycle from extension publish, install and uninstall procedures”. The reported issue is that an app compiles but fails installation because a dependent extension has not been installed, so the direct response is to publish and install compatible dependencies before the dependent.

B:

“User-facing text belongs in localizable resources” concerns the alternative task “use AL labels and language translation resources rather than embedding UI messages as literals”, but the stated failure is that an app compiles but fails installation because a dependent extension has not been installed. The required measure is to publish and install compatible dependencies before the dependent.

C:

Question 796

At fictional Pinewell Electronics, the Business Central development team is supporting equipment returns and invoicing and reviewing extension environment and deployment preparation during an AL developer handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed. Which observed result would most clearly show the intended correction works?

  1. The production package hash matches the artifact that passed tests.
  2. A seeded tenant retains prior values after the new app version is applied.
  3. The extension installs after prerequisites are present and the dependency graph resolves.
  4. A locale switch displays reviewed translations without altering business logic.

Explanation

Correct Answer

C:

This is the outcome that directly verifies the intended correction: the extension installs after prerequisites are present and the dependency graph resolves. The related solution is to publish and install compatible dependencies before the dependent .app file; it is based on the principle that build success does not guarantee extension installation prerequisites. Applied here, the relevant facts are: handoff (MB820-2.2-047). The observed development issue is that an app compiles but fails installation because a dependent extension has not been installed.

Question 797

At fictional Glenhaven Foods, the Business Central development team is supporting inventory traceability and purchasing and reviewing automated testing and diagnostics during a release qualification test (MB820-5.1-165). The observed development issue is that a test alters live customer records because the developer runs the suite against production data. Which AL development or design response most directly addresses this issue?

  1. Run Business Central tests using an isolated test environment and controlled fixtures.
  2. Create independent fixtures for each test and use appropriate cleanup or transaction isolation.
  3. Use shared test helpers and a clear arrange-act-assert structure.
  4. Use the appropriate TestPage interaction and assert resulting business state.

Explanation

Correct Answer

A:

The most direct corrective response is to run Business Central tests using an isolated test environment and controlled fixtures. This addresses the specific failure where a test alters live customer records because the developer runs the suite against production data. Acceptance evidence is that the test creates and cleans up synthetic records without touching production customers. Applied here, the relevant facts are: test (MB820-5.1-165). The observed development issue is that a test alters live customer records because the developer runs the suite against production data. The question asks which AL development or design response most directly addresses this issue.

Incorrect Answers

B:

“Create independent fixtures for each test and use appropriate cleanup or transaction isolation” supports the separate task “create independent fixtures for each test and use appropriate cleanup or transaction isolation”, not the reported problem: a test alters live customer records because the developer runs the suite against production data. This case instead calls for “run Business Central tests using an isolated test environment and controlled fixtures”.

The observed development issue is that a test alters live customer records because the developer runs the suite against production data. Which recurring engineering check would best prevent this issue from returning?

  1. Include state assertions after critical page actions.
  2. Verify environment targeting before test execution.
  3. Require tests for every new posting rule.
  4. Run report regression checks after dataset changes.

Explanation

Correct Answer

B:

The ongoing check is to verify environment targeting before test execution. This helps detect recurrence when a test alters live customer records because the developer runs the suite against production data. The associated correction is to run Business Central tests using an isolated test environment and controlled fixtures; a confirming result is that the test creates and cleans up synthetic records without touching production customers.

The required measure is to verify environment targeting before test execution.

D:

The proposed “Run report regression checks after dataset changes” tests a different control: assert expected dataset values or generated output with representative fixtures. The reported condition is that a test alters live customer records because the developer runs the suite against production data; the more direct action is to verify environment targeting before test execution.

Question 799

At fictional Glenhaven Foods, the Business Central development team is supporting inventory traceability and purchasing and reviewing automated testing and diagnostics during a release qualification test (MB820-5.1-165). The observed development issue is that a test alters live customer records because the developer runs the suite against production data. Which observed result would most clearly show the intended correction works?

  1. The build is blocked when an AL test codeunit fails.
  2. A changed report that omits lines or totals fails the test.
  3. Tests produce consistent results when executed alone or in different orders.
  4. The test creates and cleans up synthetic records without touching production customers.

Explanation

Correct Answer

D:

This is the outcome that directly verifies the intended correction: the test creates and cleans up synthetic records without touching production customers. The related solution is to run Business Central tests using an isolated test environment and controlled fixtures; it is based on the principle that test isolation must include the underlying business database. Applied here, the relevant facts are: test (MB820-5.1-165). The observed development issue is that a test alters live customer records because the developer runs the suite against production data. The question asks which observed result would most clearly show the intended correction works.

Incorrect Answers

A:

“The build is blocked when an AL test codeunit fails” concerns the separate step “configure and execute supported Business Central tests in the Test Toolkit or automated test runner”. The reported issue is that a test alters live customer records because the developer runs the suite against production data, so the direct response is to the test creates and cleans up synthetic records without touching production customers.

B:

The observed development issue is that a test alters live customer records because the developer runs the suite against production data. Which Business Central or AL development principle best explains the right response?

  1. UI automation should validate outcomes, not only control presence.
  2. Deterministic testing avoids hidden inter-test dependencies.
  3. Test isolation must include the underlying business database.
  4. Upgrade testing differs from clean-install testing.
