Exam PL-400 topic 3 question 30 discussion

The correct solution to improve performance and resolve the issue is: B. Replace the existing code segment with the following code segment: plaintext Copy Edit Concurrent(ClearCollect(collectNeighborList, Filter(NeighborList, Status = "Active")), ClearCollect(collectRealtorList, CompanyList), ClearCollect(collectRegions, RegionList)) Explanation: Concurrent allows multiple operations to run at the same time, instead of sequentially as in the original code. This can significantly improve the app's performance when loading multiple collections. By using Concurrent, you prevent the app from waiting for one operation to complete before starting the next, which can reduce the load time and improve responsiveness.

B is correct answer. The Concurrent method is used to run multiple actions at the same time. In the existing code, all three ClearCollect methods are running sequentially. This means that the first ClearCollect method will finish running before the second ClearCollect method starts running, and so on. This can cause the app to run slowly, especially if the collections are large. The Concurrent method allows you to run multiple actions at the same time. This can help to improve the performance of your app by reducing the amount of time it takes to run all of the ClearCollect methods.
