Question 200

At Brookside Manufacturing, the plant software team is implementing a work-order system upgrade under requirements for planned downtime and production traceability. The team says the following incident was fixed: A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. Which result BEST proves the intended fix is effective?

  1. The component binds correctly to the intended column and validation rejects incompatible configuration.
  2. The control handles two different view layouts without exceptions and shows only available columns.
  3. Multiple unchanged updateView invocations do not trigger repeated identical service requests.
  4. After repeated navigation no duplicate event handlers fire and memory use remains stable.

Explanation

Correct Answer

C:

Multiple unchanged updateView invocations do not trigger repeated identical service requests. This directly tests whether the reported failure has been corrected: A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The intended action was Compare relevant changed properties and cache scoped results to avoid unnecessary calls on rerender. The observed Brookside Manufacturing outcome is stronger evidence than a completed ticket or a saved configuration alone.

Incorrect Answers

A:

The component binds correctly to the intended column and validation rejects incompatible configuration. Such evidence would validate a different change: A PCF text control expects a numeric input but its component manifest declares the bound property as text. It follows the separate remedy Align the manifest property type, usage and bound column with the control's supported contract. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.

B:

The control handles two different view layouts without exceptions and shows only available columns. Such evidence would validate a different change: A PCF grid assumes every dataset column is returned and crashes when a view omits an optional field. It follows the separate remedy Check dataset metadata and column availability before accessing values, with a defined empty-state fallback. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.

D:

After repeated navigation no duplicate event handlers fire and memory use remains stable. Such evidence would validate a different change: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. It follows the separate remedy Remove subscriptions, listeners and allocated resources in the destroy lifecycle method. The Brookside Manufacturing scenario instead reports A PCF control performs the same network fetch on every updateView even when input properties remain unchanged. The decisive observation must be: Multiple unchanged updateView invocations do not trigger repeated identical service requests.

Question 201

At Silvercrest University, the research IT team is implementing a laboratory scheduling app under requirements for research data controls. The architecture review finds: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. Which change BEST resolves this specific problem?

  1. Use the framework Web API service when supported by the host and scoped credentials.
  2. Add the compiled control to the correct solution and publish/assign it through the supported component packaging workflow.
  3. Remove subscriptions, listeners and allocated resources in the destroy lifecycle method.
  4. Use supported PCF Utility dialogs or host notifications at deliberate user interaction points.

Explanation

Correct Answer

C:

Remove subscriptions, listeners and allocated resources in the destroy lifecycle method. This specifically addresses A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. For Silvercrest University, the design decision changes the underlying Power Platform solution behavior rather than an unrelated surface setting. A measurable acceptance result is: After repeated navigation no duplicate event handlers fire and memory use remains stable.

Incorrect Answers

A:

Use the framework Web API service when supported by the host and scoped credentials. This is a plausible technique for a DIFFERENT requirement: A PCF control calls Dataverse using a separately hard-coded HTTP endpoint and token even though it runs inside Power Apps. The Silvercrest University failure described here instead concerns A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. That choice does not establish the required correction; the acceptance result must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

B:

Add the compiled control to the correct solution and publish/assign it through the supported component packaging workflow. This is a plausible technique for a DIFFERENT requirement: A PCF package deploys successfully but the component does not appear in the targeted Dataverse solution. The Silvercrest University failure described here instead concerns A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. That choice does not establish the required correction; the acceptance result must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

D:

Use supported PCF Utility dialogs or host notifications at deliberate user interaction points. This is a plausible technique for a DIFFERENT requirement: A reusable PCF control needs to notify the user but displays uncontrolled JavaScript alerts during every data refresh. The Silvercrest University failure described here instead concerns A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. That choice does not establish the required correction; the acceptance result must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

Question 202

At Silvercrest University, the research IT team is implementing a laboratory scheduling app under requirements for research data controls. After the proposed change, the release reviewer requires evidence for: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records.

  1. The component binds correctly to the intended column and validation rejects incompatible configuration.
  2. After repeated navigation no duplicate event handlers fire and memory use remains stable.
  3. The control appears in the target environment and can be selected for the intended field or dataset.
  4. Both existing and newly configured forms load a valid component after the managed update.

Explanation

Correct Answer

B:

After repeated navigation no duplicate event handlers fire and memory use remains stable. This directly tests whether the reported failure has been corrected: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records.

The decisive observation must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

D:

Both existing and newly configured forms load a valid component after the managed update. Such evidence would validate a different change: A developer changes the PCF component's namespace and name without updating existing form references. It follows the separate remedy Keep stable manifest identity or plan a supported migration of bound component references before deployment. The Silvercrest University scenario instead reports A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. The decisive observation must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

Question 203

At Highland Education, the campus services team is implementing an apprenticeship management app under requirements for secure integration and predictable performance. During the implementation check, developers discover: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. Which change BEST resolves this specific problem?

  1. Remove subscriptions, listeners and allocated resources in the destroy lifecycle method.
  2. Call the framework output-changed callback and return the current value through getOutputs.
  3. Align the manifest property type, usage and bound column with the control's supported contract.
  4. Check dataset metadata and column availability before accessing values, with a defined empty-state fallback.

  1. The same control remains usable on narrow viewports without clipping or horizontal overflow.
  2. The control appears in the target environment and can be selected for the intended field or dataset.
  3. Editing the control marks the bound field as changed and save persists the correct value.
  4. After repeated navigation no duplicate event handlers fire and memory use remains stable.

Explanation

Correct Answer

D:

After repeated navigation no duplicate event handlers fire and memory use remains stable. This directly tests whether the reported failure has been corrected: A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. The intended action was Remove subscriptions, listeners and allocated resources in the destroy lifecycle method. The observed Highland Education outcome is stronger evidence than a completed ticket or a saved configuration alone.

Incorrect Answers

A:

The same control remains usable on narrow viewports without clipping or horizontal overflow. Such evidence would validate a different change: A PCF chart works on a wide desktop form but overflows a narrow mobile layout. It follows the separate remedy Implement responsive sizing from the host allocated width and test the container at realistic screen sizes. The Highland Education scenario instead reports A PCF control leaks browser event listeners when users navigate repeatedly between model-driven records. The decisive observation must be: After repeated navigation no duplicate event handlers fire and memory use remains stable.

B:

Question 205

At Harborline Logistics, the warehouse applications team is implementing a dispatch automation rollout under requirements for inventory consistency across sites. The architecture review finds: A dataset PCF renders only the first page of rows and incorrectly claims that no more related records exist. Which change BEST resolves this specific problem?

  1. Add the compiled control to the correct solution and publish/assign it through the supported component packaging workflow.
  2. Use the supported dataset paging interface to request additional pages while respecting filters and permissions.
  3. Initialize framework services and event wiring in init and defer record-dependent rendering until updateView.
  4. Align the manifest property type, usage and bound column with the control's supported contract.

Explanation
