Question 230
At the Foxbridge retail logistics hub after a wider deployment, a control registers global event listeners and leaves them active after form navigation. The operations team needs a supportable remediation with evidence for the handover. Which technical explanation best accounts for the observed problem?
Explanation
Correct Answer
The observed behavior follows from the fact that detached controls can retain event handlers and memory allocations. A focused repair is to release listeners and external resources in the PCF destroy method, with repeated navigation does not accumulate duplicate listeners as the proposed proof. In the Foxbridge retail logistics hub, assess this against the documented pcf cleanup scenario.
Incorrect Answers
This explanation corresponds to code app connector binding rather than the symptoms in the case. The controlling cause here is that detached controls can retain event handlers and memory allocations; the unrelated mechanism does not account for the observed behavior. For case R082-PL400-CASE-0058, the decisive context is the 2 deployment setting at the Foxbridge retail logistics hub.
“The manifest defines the public contract exposed to hosts” is not the controlling explanation for at the Foxbridge retail logistics hub after a wider deployment, a control registers global event listeners and leaves them active after form navigation. The operations team needs a supportable remediation with evidence for the handover. The cited causal relationship is detached controls can retain event handlers and memory allocations. The matching answer is “Detached controls can retain event handlers and memory allocations”.
“Local development output alone is not a deployable solution asset” is not the controlling explanation for at the Foxbridge retail logistics hub after a wider deployment, a control registers global event listeners and leaves them active after form navigation. The operations team needs a supportable remediation with evidence for the handover. The cited causal relationship is detached controls can retain event handlers and memory allocations. The matching answer is “Detached controls can retain event handlers and memory allocations”.
