質問 # 176
A developer needs to include a Visualforce page in the detail section of a page layout for the Account object, but does not see the page as an available option in the Page Layout Editor. Which attribute must the developer include in the <apex:page> tag to ensure the Visualforce page can be embedded in a page layout?
正解：D
質問 # 177
The following code snippet is executed by a Lightning web component in an environment with more than

正解：A
質問 # 178
What will be the output in the debug log in the event of a QueryException during a call to the aQuery method if it is following example?
public class myclass { class CustomException extends Exception {}
public static Account aQuery() {
Account theAccount;
try {
system.debug( ' Querying Accounts. ' );
theAccount = [SELECT Id FROM Account WHERE CreatedDate > TODAY];
}
catch (CustomException ex) {
system.debug( ' Custom Exception. ' );
}
catch (QueryException ex) {
system.debug( ' Query Exception. ' );
}
finally {
system.debug( ' Done. ' );
}
return theAccount;
}
正解：A
解説：
Answer C is correct. Salesforce delivery depends on repeatable testing and controlled deployment. Apex tests create isolated data, validate behavior, and supply code coverage for production deployment. Salesforce CLI, scratch orgs, sandboxes, debug logs, trace flags, and Apex Jobs give developers the tooling needed to build, test, diagnose, and release changes across environments. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Salesforce Apex Developer Guide, Salesforce CLI Developer Guide, Tooling API documentation, and Salesforce Help deployment guidance. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
質問 # 179
While writing an Apex class, a developer wants to make sure that all functionality being developed is handled as specified by the requirements.
Which approach should the developer use to be sure that the Apex class is working according to specifications?
正解：C
解説：
To ensure that the Apex class is functioning according to the specified requirements, the developer should write a test class that executes the business logic and verifies that it behaves as expected.
Option A: Create a test class to execute the business logic and run the test in the Developer Console.
Correct Approach.
Writing a test class allows the developer to create unit tests that verify the functionality of the Apex class.
Test methods can assert that the class behaves as intended under various conditions, ensuring compliance with requirements.
Running the test in the Developer Console allows the developer to see the results and debug if necessary.
Benefits:
Automated Testing: Ensures repeatability and consistency in testing.
Code Coverage: Helps achieve required code coverage for deployment.
Regression Testing: Facilitates detection of future changes that might break existing functionality.
While running code in Execute Anonymous allows for quick tests, it is not suitable for thorough testing.
It doesn't provide assertions to verify that the output matches expected results.
Tests run in Execute Anonymous are not saved and cannot be rerun easily for regression testing.
Using savepoints and rollbacks can help in testing DML operations without committing changes to the database.
However, this doesn't ensure that the class meets the functional requirements.
Adding try/catch blocks can handle exceptions but does not verify that the class functions as specified.
Exception handling is a part of robust code but doesn't replace the need for testing.
Reference:

Best Practices for Unit Testing
Option B: Run the code in an Execute Anonymous block in the Developer Console.
Less Effective.
Anonymous Blocks
Option C: Include a savepoint and Database.rollback().
Not Sufficient.
Using Savepoints and Rollbacks
Option D: Include a try/catch block to the Apex class.
Not Sufficient.
Exception Handling in Apex
Conclusion:
Writing a test class is the best way to ensure that the Apex class works according to the specifications.
Test classes allow for comprehensive testing with assertions, providing confidence that the code meets the requirements.
質問 # 180
A developer created a trigger on the Account object and wants to test if the trigger is properly bulkified. The developer team decided that the trigger should be tested with 200 account records with unique names.
What two things should be done to create the test data within the unit test with the least amount of code?
Choose 2 answers
正解：C、D
解説：
Why Use Static Resources andTest.loadData?
C: Static resources allow you to define reusable test data (e.g., in a CSV file).
D:Test.loadDatasimplifies loading bulk test data into test classes from static resources.
Why Not Other Options?
A: Using@isTest(seeAllData=true)violates test isolation principles and is discouraged.
B:@isTest(isParallel=true)is used for parallel execution, not for creating test data.
