Question 140

At Timberline Foods, the supply-chain systems team is implementing a vendor onboarding project under requirements for continuous approved supplier status. The team says the following incident was fixed: A form script is registered twice for the same event and submits two identical external requests whenever status changes. Which result BEST proves the intended fix is effective?

  1. A single change event produces one intended request and the form's event list contains no duplicate registration.
  2. An unprivileged user's Web API call cannot read the field even when form scripts are bypassed.
  3. The handler reads and updates the field on the currently open form in both forms without cross-record state leaks.
  4. The form loads relevant records without a full table transfer and telemetry shows improved response time.

Explanation

Correct Answer

A:

A single change event produces one intended request and the form's event list contains no duplicate registration. This directly tests whether the reported failure has been corrected: A form script is registered twice for the same event and submits two identical external requests whenever status changes. The intended action was Consolidate and register the handler once using an explicit event library/function mapping. The observed Timberline Foods outcome is stronger evidence than a completed ticket or a saved configuration alone.

Incorrect Answers

B:

An unprivileged user's Web API call cannot read the field even when form scripts are bypassed. Such evidence would validate a different change: An application uses client-side field hiding as its only restriction on confidential payroll columns. It follows the separate remedy Enforce access through Dataverse permissions or field security and use JavaScript hiding solely as a usability aid. The Timberline Foods scenario instead reports A form script is registered twice for the same event and submits two identical external requests whenever status changes. The decisive observation must be: A single change event produces one intended request and the form's event list contains no duplicate registration.

C:

The handler reads and updates the field on the currently open form in both forms without cross-record state leaks. Such evidence would validate a different change: A model-driven form script uses a global form object and edits the wrong record when the same library runs on another form. It follows the separate remedy Accept the execution context and obtain formContext from the event instead of assuming one global form instance. The Timberline Foods scenario instead reports A form script is registered twice for the same event and submits two identical external requests whenever status changes. The decisive observation must be: A single change event produces one intended request and the form's event list contains no duplicate registration.

D:

The form loads relevant records without a full table transfer and telemetry shows improved response time. Such evidence would validate a different change: A script retrieves every row from a large table on form load and the model-driven page becomes unresponsive. It follows the separate remedy Use filtered server-side Xrm.WebApi queries with selected columns and bounded pagination. The Timberline Foods scenario instead reports A form script is registered twice for the same event and submits two identical external requests whenever status changes. The decisive observation must be: A single change event produces one intended request and the form's event list contains no duplicate registration.

Question 141

At Juniper Media, the production operations team is implementing a content licensing automation under requirements for governed asset rights. The architecture review finds: A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. Which change BEST resolves this specific problem?

  1. Invoke the Dataverse Web API using the supported client API and handle response/error promises.
  2. Configure a supported model-driven command with Power Fx visibility rules or appropriate command tooling.
  3. Separate initialization from save events and register lifecycle-specific handlers with a re-entry guard.
  4. Enforce access through Dataverse permissions or field security and use JavaScript hiding solely as a usability aid.

Explanation

Correct Answer

C:

Separate initialization from save events and register lifecycle-specific handlers with a re-entry guard. This specifically addresses A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. For Juniper Media, the design decision changes the underlying Power Platform solution behavior rather than an unrelated surface setting. A measurable acceptance result is: Opening the form does not create unintended saves while an intentional save invokes the validation once.

Incorrect Answers

A:

Invoke the Dataverse Web API using the supported client API and handle response/error promises. This is a plausible technique for a DIFFERENT requirement: A custom button creates a record by sending a raw fetch request with omitted required authentication context. The Juniper Media failure described here instead concerns A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. That choice does not establish the required correction; the acceptance result must be: Opening the form does not create unintended saves while an intentional save invokes the validation once.

B:

Configure a supported model-driven command with Power Fx visibility rules or appropriate command tooling. This is a plausible technique for a DIFFERENT requirement: A command-bar action must be visible only when the selected record is eligible but the developer relies on a hidden HTML button. The Juniper Media failure described here instead concerns A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. That choice does not establish the required correction; the acceptance result must be: Opening the form does not create unintended saves while an intentional save invokes the validation once.

D:

Enforce access through Dataverse permissions or field security and use JavaScript hiding solely as a usability aid. This is a plausible technique for a DIFFERENT requirement: An application uses client-side field hiding as its only restriction on confidential payroll columns.

Question 142

At Juniper Media, the production operations team is implementing a content licensing automation under requirements for governed asset rights. After the proposed change, the release reviewer requires evidence for: A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. Which result BEST proves the intended fix is effective?

  1. The record is created once with proper privileges and failures surface a meaningful notification rather than a silent error.
  2. Opening the form does not create unintended saves while an intentional save invokes the validation once.
  3. The command appears only in eligible record states and executes the approved action for the selected row.
  4. The script locates the intended field on each form and reports a controlled error if the attribute is unavailable.

Explanation

Correct Answer

B:

Opening the form does not create unintended saves while an intentional save invokes the validation once. This directly tests whether the reported failure has been corrected: A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. The intended action was Separate initialization from save events and register lifecycle-specific handlers with a re-entry guard.

D:

The script locates the intended field on each form and reports a controlled error if the attribute is unavailable. Such evidence would validate a different change: An OnChange handler fails with an undefined field error after a form designer renames a control but not its Dataverse column. It follows the separate remedy Use supported formContext attribute APIs and verify logical column names independently of UI control labels. The Juniper Media scenario instead reports A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. The decisive observation must be: Opening the form does not create unintended saves while an intentional save invokes the validation once.

Question 143

At Meadowbrook Finance, the regulated systems team is implementing a payments operations refresh under requirements for segregation of duties. During the implementation check, developers discover: A developer attaches an OnLoad handler that immediately executes save and causes repeated form reloads. Which change BEST resolves this specific problem?

  1. Enforce access through Dataverse permissions or field security and use JavaScript hiding solely as a usability aid.
  2. Consolidate and register the handler once using an explicit event library/function mapping.
  3. Re-retrieve required output state from Dataverse after the operation and account for asynchronous or server-side logic.
  4. Separate initialization from save events and register lifecycle-specific handlers with a re-entry guard.

Explanation
