Question 190

An extension build generated from one commit works locally but deployment carries an older artifact from another branch. The developer recommends the following change: Use a reproducible AL build and release pipeline with fixed source revision and dependency versions. Which technical explanation most directly justifies it in this case?

  1. Continuous integration should produce the same versioned package from controlled source and dependencies for promotion
  2. The AL debugger exposes call flow and variable state at the problematic trigger or subscriber
  3. AL packaging provides a deployable extension artifact decoupled from the developer's interactive editor session
  4. AL multilingual support relies on resources that map caption/label identifiers to localized translations

Explanation

Correct Answer

A:

Continuous integration should produce the same versioned package from controlled source and dependencies for promotion. It connects the proposed action to the exact failure or requirement—An extension build generated from one commit works locally but deployment carries an older artifact from another branch. Confirmation would be artifact metadata, test results, and release logs all trace to the same approved source commit.

Incorrect Answers

B:

That mechanism explains why the alternative action—set vs code breakpoints and debug the extension execution path in the sandbox—helps in another case. It does not justify the proposed fix here; continuous integration should produce the same versioned package from controlled source and dependencies for promotion. The distinguishing requirement is: An extension build generated from one commit works locally but deployment carries an older artifact from another branch.

C:

That mechanism explains why the alternative action—build the al project into an .app package and promote the tested artifact through the release process—helps in another case. It does not justify the proposed fix here; continuous integration should produce the same versioned package from controlled source and dependencies for promotion. The distinguishing requirement is: An extension build generated from one commit works locally but deployment carries an older artifact from another branch.

D:

That mechanism explains why the alternative action—generate and maintain xlf translations and use translatable al captions and labels—helps in another case. It does not justify the proposed fix here; continuous integration should produce the same versioned package from controlled source and dependencies for promotion. The distinguishing requirement is: An extension build generated from one commit works locally but deployment carries an older artifact from another branch.

Question 191

An extension build generated from one commit works locally but deployment carries an older artifact from another branch. The team implemented a change aligned with this plan: Use a reproducible AL build and release pipeline with fixed source revision and dependency versions. Which acceptance result specifically verifies that the reported problem is resolved?

  1. A reproducing transaction reaches the breakpoint and the inspected values explain the failing branch
  2. Artifact metadata, test results, and release logs all trace to the same approved source commit
  3. The promoted package ID and version match the tested build and installation passes smoke checks
  4. The published language pack shows translated labels for the selected user language and no untranslated hardcoded strings in scope

Explanation

Correct Answer

B:

Artifact metadata, test results, and release logs all trace to the same approved source commit. This is stronger than an unrelated health check because the desired design action is use a reproducible al build and release pipeline with fixed source revision and dependency versions, and continuous integration should produce the same versioned package from controlled source and dependencies for promotion. The local requirement is: An extension build generated from one commit works locally but deployment carries an older artifact from another branch.

Incorrect Answers

A:

This would verify set vs code breakpoints and debug the extension execution path in the sandbox, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: An extension build generated from one commit works locally but deployment carries an older artifact from another branch. The decisive local proof is artifact metadata, test results, and release logs all trace to the same approved source commit.

C:

This would verify build the al project into an .app package and promote the tested artifact through the release process, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: An extension build generated from one commit works locally but deployment carries an older artifact from another branch. The decisive local proof is artifact metadata, test results, and release logs all trace to the same approved source commit.

D:

The decisive local proof is artifact metadata, test results, and release logs all trace to the same approved source commit.

Question 192

An extension build generated from one commit works locally but deployment carries an older artifact from another branch. A targeted trial still reproduces the original gap after the team attempted this change: Use a reproducible AL build and release pipeline with fixed source revision and dependency versions. Which repair directly addresses the remaining defect?

  1. Point the debugger at the correct environment and executable path, then reproduce and inspect the failing AL call
  2. Rebuild from the approved source revision and deploy that package rather than an untracked local copy
  3. Repair dependency pinning and artifact promotion so the pipeline deploys only its validated build
  4. Regenerate or correct translation units, remove hardcoded UI text, and ship matching XLF resources

Explanation

Correct Answer

C:

Repair dependency pinning and artifact promotion so the pipeline deploys only its validated build. This directly addresses the remaining defect for the requirement—An extension build generated from one commit works locally but deployment carries an older artifact from another branch. It restores the mechanism described here: continuous integration should produce the same versioned package from controlled source and dependencies for promotion.

Incorrect Answers

A:

This correction is for the separate condition: A supplier rebate extension fails only in a particular codeunit path and support needs to inspect live variables safely in a sandbox. It would not directly restore the intended behavior in this situation: An extension build generated from one commit works locally but deployment carries an older artifact from another branch. Here, repair dependency pinning and artifact promotion so the pipeline deploys only its validated build, because continuous integration should produce the same versioned package from controlled source and dependencies for promotion.

B:

This correction is for the separate condition: A release engineer must move a tested finance extension into a managed deployment pipeline from source control. It would not directly restore the intended behavior in this situation: An extension build generated from one commit works locally but deployment carries an older artifact from another branch. Here, repair dependency pinning and artifact promotion so the pipeline deploys only its validated build, because continuous integration should produce the same versioned package from controlled source and dependencies for promotion.

D:

This correction is for the separate condition: A regional service team updates an AL UI app but German users still see hardcoded help strings. It would not directly restore the intended behavior in this situation: An extension build generated from one commit works locally but deployment carries an older artifact from another branch. Here, repair dependency pinning and artifact promotion so the pipeline deploys only its validated build, because continuous integration should produce the same versioned package from controlled source and dependencies for promotion.

Question 193

A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. Which single AL development or architecture change best resolves this requirement without redesigning unrelated workflows?

  1. Add a tableextension object with a properly numbered custom field on the existing table
  2. Add a pageextension that places the new control in the target extensible card page layout
  3. Create an enumextension targeting an extensible enumeration
  4. Choose the correct Card versus List page type based on record interaction requirements

Explanation

Correct Answer

A:

This targets the concrete requirement—A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged. The team can establish success when a new field persists through a sandbox app upgrade and is visible to code through the target table.

Incorrect Answers

B:

This choice primarily fits a different requirement: Finance wants a custom approval note displayed beside existing fields on a customer card. There, a pageextension composes new controls and actions into a compatible page without cloning the base page. In the current situation, A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged. Acceptance requires a new field persists through a sandbox app upgrade and is visible to code through the target table.

C:

This choice primarily fits a different requirement: A purchasing add-on needs an extra Order Channel value for a shared status enumeration used by multiple extensions. There, an enumextension adds supported values to an extensible enum without inventing a separate incompatible option field. In the current situation, A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged. Acceptance requires a new field persists through a sandbox app upgrade and is visible to code through the target table.

D:

This choice primarily fits a different requirement: A controller wants a one-record invoice detail screen but receives the multi-record layout designed for quick browsing. There, card pages emphasize one record's detail while list pages present multiple records for searching and navigation. In the current situation, A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged. Acceptance requires a new field persists through a sandbox app upgrade and is visible to code through the target table.

Question 195

A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The team implemented a change aligned with this plan: Add a tableextension object with a properly numbered custom field on the existing table. Which acceptance result specifically verifies that the reported problem is resolved?

  1. The original card opens with the custom control in the approved location and existing page behavior is preserved
  2. The existing standard values and the new extension value are selectable wherever the enum is supported
  3. A new field persists through a sandbox app upgrade and is visible to code through the target table
  4. Users can edit one detailed record or scan multiple rows exactly as the specified workflow requires

Explanation

Correct Answer

C:

A new field persists through a sandbox app upgrade and is visible to code through the target table. This is stronger than an unrelated health check because the desired design action is add a tableextension object with a properly numbered custom field on the existing table, and the tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged. The local requirement is: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition.

Incorrect Answers

A:

This would verify add a pageextension that places the new control in the target extensible card page layout, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The decisive local proof is a new field persists through a sandbox app upgrade and is visible to code through the target table.

B:

This would verify create an enumextension targeting an extensible enumeration, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The decisive local proof is a new field persists through a sandbox app upgrade and is visible to code through the target table.

D:

This would verify choose the correct card versus list page type based on record interaction requirements, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. The decisive local proof is a new field persists through a sandbox app upgrade and is visible to code through the target table.

Question 196

A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. A targeted trial still reproduces the original gap after the team attempted this change: Add a tableextension object with a properly numbered custom field on the existing table. Which repair directly addresses the remaining defect?

  1. Fix the pageextension target or layout placement and republish it rather than replacing the standard card page
  2. Verify that the target enum is extensible and correct the enumextension value ID and dependency
  3. Change the custom page's PageType and layout to match the intended single-record or multi-record workflow
  4. Correct the extension target or field definition and republish the tableextension rather than editing the base table

Explanation

Correct Answer

D:

Correct the extension target or field definition and republish the tableextension rather than editing the base table. This directly addresses the remaining defect for the requirement—A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. It restores the mechanism described here: the tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged.

Incorrect Answers

A:

This correction is for the separate condition: Warehouse clerks need to see a new packaging status field on the standard item card page. It would not directly restore the intended behavior in this situation: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. Here, correct the extension target or field definition and republish the tableextension rather than editing the base table, because the tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged.

B:

This correction is for the separate condition: A shipping partner must introduce one new Delivery Mode enum member while keeping the standard choices available. It would not directly restore the intended behavior in this situation: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. Here, correct the extension target or field definition and republish the tableextension rather than editing the base table, because the tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged.

C:

This correction is for the separate condition: A vendor clerk needs a list-style view for many open purchase headers but the proposed UI is built as a single-record card. It would not directly restore the intended behavior in this situation: A retailer needs a loyalty risk score stored on Customer without editing Microsoft's Customer table definition. Here, correct the extension target or field definition and republish the tableextension rather than editing the base table, because the tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged.
