Salesforce Certified Platform Developer II - Multiple Choice 認定 Plat-Dev-301 試験問題 (Q29-Q34):

質問 # 29
A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and 5P3 {created in order), before the final execution of the process.
During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls 2 roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a Funtime error occurs.
Why does the developer receive a runtime error?

A. The developer has too many DML statements between the savepoints.
B. The developer should have called SF2 before calling SP3.
C. SP3 became invalid when SP1 was rolled back.
D. The developer used too many savepoints in one trigger session.

正解：C

解説：
Savepoints in Apex are markers within a transaction and rolling back to an earlier savepoint (SP1) invalidates any savepoints created after it. Thus, SP3 is invalidated when the code rolls back to SP1, causing a runtime error when a rollback to SP3 is attempted.

質問 # 30
A developer is writing a Jest test for a Lightning web component that conditionally displays child components based on a user's checkbox selections.
What should the developer do to properly test that the correct components display and hide for each scenario?

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

正解：C

解説：
To ensure that the DOM is clean before each test runs, the developer should use the afterEach() method to reset it. This is part of the setup and teardown process in Jest tests, which helps to avoid state leakage between tests. Reference:
Jest Globals afterEach

質問 # 31
Consider the Apex class below that defines a RemoteAction used on 2 Visualforce search page.

Which code snippet will assert that the remote action returned the correct Account? A)

B)

C)

D)

A. Option A
B. Option D
C. Option C
D. Option B

正解：C

解説：
The correct code snippet to assert that the remote action returned the correct Account is option C. This is because the getAccount method is a global static method within the MyRemoter class and can be directly called without needing to instantiate an object of the class.

質問 # 32
Which scenario requires a developer to use an Apex callout
Instead of Outbound Messaging?

A. The target system uses a SCAP API.
B. The target system uses a REST APL.
C. The callout needs to be invoked from a flow.
D. The callout needs to be asynchronous.

正解：B

解説：
Outbound Messaging in Salesforce provides a way to send notifications from Salesforce to external applications using SOAP-based web service calls. However, when the target system requires interactions with RESTful web services, a developer must use an Apex callout. This is because Outbound Messaging is limited to SOAP and cannot directly interact with REST APIs. Apex callouts provide the flexibility to make HTTP requests to REST endpoints, thus allowing developers to programmatically interact with virtually any web service provided by external systems.

質問 # 33
Business rules require a Contact ta 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. Insect method with a11orNone SEL LO alee,
B. Use the Database. Delete method if the Contact insertion fails.
C. Use setSaverpoint (1) and rollback() with a try-catch block.
D. Disable validation rules on Contacts and set default values with a trigger.

正解：C

解説：
When developing a custom screen that requires both an Account and Contact to be created together, using setSavepoint() and rollback() within a try-catch block is a reliable way to ensure that if the Contact creation fails, the Account creation is also rolled back, maintaining data integrity.
