Salesforce Platform Developer II Sample Questions (Q159-Q164):

NEW QUESTION # 159
There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user. The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, "Maximum view state size limit exceeded". What step should the developer take to resolve this issue?

A. Adjust any code that filters by picklist values since they are not indexed.
B. Split the layout to filter records in one Visualforce page and display the list of records in a second page using the same Apex controller.
C. Use a StandardSetController or SOQL LIMIT in the Apex controller to limit the number of records displayed at a time.
D. Remove instances of the transient keyword from the Apex controller to avoid the view state error.

Answer: C

Explanation:
The two symptoms described-slow load times and "Maximum view state size limit exceeded"-are both caused by Large Data Volumes (LDV) being handled improperly in the UI. When a user selects a filter that returns thousands of records, the SOQL query takes longer to execute, and the resulting list is stored in the controller's memory. Because Visualforce serializes all non-transient controller variables into a hidden form field (the View State), large lists quickly exceed the 135KB limit.
The correct resolution is to implement Pagination (Option D). By using the StandardSetController, a developer can easily manage large sets of data by loading only a small subset (e.g., 20 records) into the View State at a time. Users can then navigate through "Pages" of data. Alternatively, adding a LIMIT to the SOQL query prevents the application from attempting to process more data than the platform limits allow.123 Option A is incorrect because picklist fields can be indexed by Salesforce Support or if they are part of a custom index. Option B is the opposite of what is neede4d; adding transient reduces the View State. Option C adds unnecessary complexity without addressing the underlying data volume issue. Using a StandardSetController provides a built-5in, effi6cient way to handle large result sets while keeping the View State small and the page responsive.

NEW QUESTION # 160
A developer is writing a Jest for a Lightning web component that conditionally displays child components based on a user's checkbox selections.
What should the developer do to property test that the correct components display and hide for each scenario?

A. Reset the DOM after each test with the after Each method.
B. Create a new describe block for each test
C. Create a new jsdom instance for each test
D. Add a teardown block to reset the DOM after each test.

Answer: B

NEW QUESTION # 161
A developer sees test failures in the sandbox but not in production. No code or metadata changes have been actively made to either environment since the sandbox was created.
Which consideration should be checked to resolve the issue?

A. Ensure the Apex Classes are on the same API version.
B. Ensure the sandbox is on the same release as production.
C. Ensure Process Builder processes are inactive.
D. Ensure Workflow Rules are inactive.

Answer: B

NEW QUESTION # 162
A developer created the following test method:

The developer org has five accounts where the name starts with "Test". The developer executes this test in the Developer Console.
After the test code runs, which statement is true?

A. The test will fail.
B. There will be five accounts where the name starts with "Test".
C. There will be no accounts where the name starts with "Test".
D. There will be six accounts where the name starts with "Test".

Answer: A

Explanation:
Since the SeeAllData=true annotation is used, the test class does not have its own test data and is relying on the data in the org. The org already has accounts with the name starting with "Test", so the assertion that no accounts should exist after the deletion will fail because the test method only deletes the account that was created within its scope.

Answer: B
