質問 # 123
A developer is asked to find a way to store sacret data with an ability to specify which profiles and users can access which secrets.
What should be used to store this data?
正解：B
解説：
Custom metadata types are the optimal way to store secret data that needs to be accessed by certain profiles and users. Access to custom metadata records can be controlled by the Salesforce sharing model.

Refer to the test method below:
The test method tests an Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated to be customers. The test method fails at the Line 20 because of too many SOQL queries. What is the correct way to fix this? A)
B)
C)
D)
正解：B
解説：
The correct way to fix this is to add Test.startTest() before and add Test.stopTest() after Line 18 of the code. This will reset the governor limits for the code that executes between these two methods, and allow the test to run without hitting the SOQL query limit.The Test.startTest() and Test.stopTest() methods are used to test code that makes a lot of queries or calls asynchronous methods12. By using these methods, the developer can isolate the code that needs more resources and verify that it does not exceed the governor limits.

質問 # 125
Universal Containers wants to use a Customer Community with Customer Community Plus licenses to allow their customers access to track how many containers they have rented and when they are due back. Universal Containers uses a Private sharing model for External users, Many of their customers are multi-national corporations with complex Account hierarchies. Each account on the hierarchy represents a department within the same business, One of the requirements is to allow certain community users within the same Account hierarchy to see several departments' containers, based on a custom junction object that relates the Contact to the various Account records that represent the departments.
Which solution solves these requirements?
正解：C
解説：
For community users within the same Account hierarchy to see records based on a custom junction object, Apex managed sharing can be used. An Apex trigger can create sharing records based on the junction object relationships, allowing users to see records from different departments as required.
質問 # 126
Refer to the test method below''
The test method calls a web service that updates an external system with Account information and sets the Accounts integration_Updated__c checkbox to True when it completes. The test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web service callouts." A) B)
C)
D)
正解：A
解説：
The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the method invocation, and finally Test.stopTest(). This ensures the mock callout is used.
質問 # 127
A developer is building a complex commission calculation engine in Apex that is called from an Opportunity trigger. During QA it was reported that the calculations are incorrect.
The developer has representative test data and passing test methods in their developer sandbox.
Which three tools or techniques could the developer use to execute the code and pause it at key lines to visually inspect values of various Apex variables?
Choose 3 answers
正解：A、D、E
解説：
To debug and troubleshoot the commission calculation engine, a developer can use several tools provided by Salesforce to inspect and pause the execution of Apex code.
Apex Interactive Debugger: It allows real-time debugging of Apex code execution. With this tool, a developer can set breakpoints, step through code, inspect variables, and evaluate expressions.
Developer Console: Although the Developer Console does not allow interactive debugging, it does provide the ability to view logs that capture the execution of code. Debug logs can be inspected to understand the flow of execution and values of variables at different points in time.
Apex Replay Debugger: This tool is part of Salesforce Extensions for Visual Studio Code. It allows a developer to replay a debug log as if they are stepping through the code line by line, which can be very useful to inspect the state of variables at specific points in the execution.
