Salesforce Platform Developer II Sample Questions (Q12-Q17):

NEW QUESTION # 12
A developer has working business logic code, but sees the following error in the test class:
You have uncommitted work pending. Please commit or rollback before calling out. What is a possible solution?

A. Use test.IsRunningTest() before making the callout to bypass it in test execution.
B. Rewrite the business logic and test classes with ©TestVisible set on the callout.
C. Call support for help with the target endpoint, as it is likely an external code error.
D. Set seeAIIData to "true" at the top of the test class, since the code does not fail in practice.

Answer: A

NEW QUESTION # 13
A developer built a Component to be used at the front desk for guests to self-register upon arrival at a kiosk. The developer is now asked to create a Component for the Utility Tray to alert Users whenever a guest has arrived at the front desk. What should be used?

A. Changelog
B. Application Event
C. Component Event
D. DML Operation

Answer: B

NEW QUESTION # 14
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. There will be six accounts where the name starts with "Test".
B. The test will fail.
C. There will be five accounts where the name starts with "Test".
D. There will be no accounts where the name starts with "Test".

Answer: B

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.

NEW QUESTION # 15

What is wrong with it?

A. Lines 1 and 6: class and method must be global
B. Line 1: class must be global
C. Line 8: method must first serialize the list to JSON before returning
D. Line 6: method must be static

Answer: D

NEW QUESTION # 16
Business rules require a Contact to always be created when a new Account is created. What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

A. Use the Database.Insert method with allOrNone set to false.
B. Use a Database Savepoint method with a try-catch block.
C. Use the Database.Delete method if the Contact insertion fails.
D. Use setSavePoint() and rollback() with a try-catch block.

Answer: D

Explanation:
This requirement calls for "Transactional Atomicity," meaning either both database operations (Account creation and Contact creation) succeed, or neither is committed to the database. In Apex, each DML statement normally acts as its own individual transaction unless managed by Savepoints.
The correct approach is to use Database.setSavepoint() and Database.rollback() within a try-catch block (Option A). The developer sets a savepoint immediately before the Account is inserted. If the Account is created successfully but the subsequent Contact insertion fails (due to a validation rule, trigger error, or system exception), the code enters the catch block. Within the catch block, the developer executes Database.
rollback(sp), which reverts the database to the state it was in before the Account was ever inserted.
Option B is technically similar but "A" provides the standard programmatic pattern name. Option C (allOrNone=false) only applies to a single list of records in one DML call and cannot link the success of an Account to a Contact. Option D (manual deletion) is an unreliable "cleanup" strategy that fails if the system crashes or if there are secondary side effects from the initial insertion. Using Savepoints ensures the platform handles the rollback safely and completely.
