Salesforce Platform Developer I (PDI) Sample Questions (Q114-Q119):
NEW QUESTION # 114
A developer created a new after insert trigger on the Lead object that creates Task records for each Lead.
After deploying to production, an existing outside integration that inserts Lead records in batches to Salesforce is occasionally reporting total batch failures being caused by the Task insert statement. This causes the integration process in the outside system to stop, requiring a manual restart.
Which change should the developer make to allow the integration to continue when some records in a batch cause failures due to the Task insert statement, so that manual restarts are not needed?
- A. Use the Database method with allow one set to false.
- B. Remove the Apex class from the integration user's profile.
- C. Deactivate the trigger before the integration runs.
- D. Use a try-catch block after the insert statement.
Answer: D
Explanation:
A try-catch block allows the batch to continue processing even if some records cause errors. Errors can be logged for review, ensuring the integration process does not stop entirely.
Reference:Error Handling in Apex
Incorrect Options:
A:Database.insertwithallowPartialwould be required for partial processing but is not mentioned.
B:Deactivating the trigger disrupts other processes.
C:Removing Apex classes is unrelated.
NEW QUESTION # 115
A developer wrote Apex code that calls out to an external system using REST API.
How should a developer write the test to prove the code is working as intended?
- A. Write a class that implements WebServiceMock.
- B. write a class that implements HTTPCalloutMock.
- C. Write a class that extends HTTPCalloutMock.
- D. Write a class that extends WerServiceMack.
Answer: B
Explanation:
When writing tests for Apex code that performs callouts to external services, Salesforce requires that callouts are mocked to ensure that tests do not depend on external systems and to allow for consistent and predictable test results.
Correct Option:
Option D: Write a class that implements HttpCalloutMock.
True.
To test HTTP callouts, you implement the HttpCalloutMock interface and provide a fake response for the HTTP request.
This mock response is then used in your test methods to simulate the callout.
The test method uses Test.setMock to set the mock class.
WebServiceMock is used for testing SOAP callouts, not REST (HTTP) callouts.
Since the code uses REST API, HttpCalloutMock is appropriate.
HttpCalloutMock is an interface, not a class. You cannot extend an interface; you implement it.
The correct approach is to implement the HttpCalloutMock interface.
Reference:
Testing HTTP Callouts by Implementing HttpCalloutMock
Incorrect Options:
Option A & C: Write a class that implements or extends WebServiceMock.
False.
Testing SOAP Callouts
Option B: Write a class that extends HttpCalloutMock.
False.
Interface vs. Class
Conclusion:
To properly test REST API callouts in Apex, you should write a class that implements HttpCalloutMock and use it in your test methods.

NEW QUESTION # 118
What are two use cases for executing Anonymous Apex code?
Choose 2 answers
- A. To schedule an Apex class to run periodically
- B. To run a batch Apex class to update all Contacts
- C. To add unit test code coverage to an org
- D. To delete 15,000 inactive Accounts in a single transaction after a deployment
Answer: A,B
Explanation:
Executing Anonymous Apex code is useful for running ad-hoc operations or administrative tasks in Salesforce.
Option A: To run a batch Apex class to update all Contacts
Valid Use Case.
Anonymous Apex can be used to initiate a batch Apex job.
The developer can write code in the Execute Anonymous window to instantiate and execute the batch class.
Example:
Database.executeBatch(new UpdateContactsBatchClass());
Anonymous Apex can be used to schedule an Apex class using System.schedule.
This is useful for setting up scheduled jobs without deploying code.
Example:
String sch = '0 0 12 * * ?'; // Cron expression for daily at noon
System.schedule('Daily Job', sch, new ScheduledApexClass());
The DML operation limit per transaction is 10,000 records.
Deleting 15,000 records in a single transaction would exceed this limit and result in a governor limit exception.
This operation would need to be done in batches.
Option C: To add unit test code coverage to an org
Not Applicable.
Anonymous Apex code does not contribute to code coverage.
Code coverage is achieved by writing test classes and methods annotated with @isTest.
Conclusion:
The two valid use cases for executing Anonymous Apex code are:
Option A: Running a batch Apex class to update all Contacts.
Option D: Scheduling an Apex class to run periodically.
Reference:
Batch Apex
Anonymous Blocks
Option D: To schedule an Apex class to run periodically
Valid Use Case.
Scheduling Apex
Anonymous Apex Execution
Options Not Suitable:
Option B: To delete 15,000 inactive Accounts in a single transaction after a deployment Not Feasible Due to Limits.
