質問 # 69
Just prior to a new deployment the Salesforce administrator, who configured a new order fulfillment process feature in a developer sandbox, suddenly left the company.
Ag part of the UAT cycle, the users had fully tested all of the changes in the sandbox and signed off on them; making the Order fulfillment feature ready for its go-live in the production environment.
Unfortunately, although a Change Set was started, it was not completed by the former administrator.
A developer is brought in to finish the deployment.
What should the developer do to identify the configuration changes that need to be moved into production?
- A. Use the Metadata API and a supported development IDE to push all of the configuration from the sandbox into production to ensure no changes are lost.
- B. Set up Continuous Integration and a Git repository to automatically merge all changes from the sandbox metadata with the production metadata.
- C. In Salesforce setup, look at the last modified date for every object to determine which should be added to the Change Set.
- D. Leverage the Setup Audit Trail to review the changes made by the departed Administrator and identify which changes should be added to the Change Set.
正解：D
質問 # 70
What is the best practice to initialize a Vizualforce page in a test class?
- A. Use controller. currentPage. setPage (MyTastfage) ;
- B. Use Test. currantPage .getParamatars put (MyTaestPaga) ;
- C. Use Test. setCurrentPage MyTestPags;
- D. Use Test. setCurrentPage (Page. MyTeatPage);
正解：D
解説：
The best practice to initialize a Visualforce page in a test class is to use Test.setCurrentPage(Page.MyTestPage). This method sets the current page context for the test class and allows the developer to access the page parameters, controller variables, and standard controller methods. This way, the developer can test the functionality and behavior of the Visualforce page and its controller in different scenarios. The other options are either invalid syntax or do not set the current page context.

質問 # 76
An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed and Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records are loaded, the Apex trigger creates Contract records.
A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.
'What is the most extendable way to update the Apex trigger to accomplish this?
- A. Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.
- B. Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.
- C. Use a list custom setting ta disable the trigger for the user who loads the data.
- D. Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.
正解：B
解説：
A hierarchy custom setting is a type of custom setting that can be used to store configuration data that can vary for different users or profiles. A hierarchy custom setting can be accessed from Apex code, and can be used to control the behavior of the code based on the user's context. By using a hierarchy custom setting, the developer can create a custom setting that can store a Boolean value that indicates whether to skip executing the logic inside the trigger for the user who loads the data. The developer can then check this value in the trigger, and bypass the trigger logic if the value is true. This way, the developer can prevent the Contract records from being created when mass loading the Opportunities, but still allow the daily users to have the Contract records created.
