質問 # 70
A large company uses Salesforce across several departments. Each department has its own Salesforce Administrator. It was agreed that each Administrator would have their own sandbox in which to test changes. Recently, users notice that fields that were recently added for one department suddenly disappear without warning. Also, Workflows that once sent emails and created tasks no longer do so. Which two statements are true regarding these issues and resolution? Choose 2 answers

• A. A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.
• B. Page Layouts should never be deployed via Change Sets, as this causes Workflows and Field-level Security to be reset and fields to disappear.
• C. The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production
• D. The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.

正解：A、C

質問 # 71
Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer. Recently a workflow rule was added so that whenever an Account is marked as a Customer, a 'Customer Since' date field is updated with today's date.
Since the addition of the workflow rule, two Account Plan records are created whenever the Account is marked as a Customer.
What might cause this to happen?

• A. The workflow rule field update is marked as 'Re-evaluate Workflow Rules After Field Change."
• B. The Apex trigger is not bulk safe and calls insert inside of a for loop.
• C. The Apex trigger does not use a static variable to ensure it only fires once.
• D. The workflow rule is configured to evaluate when a record is created and every time it is edited.

正解：A

質問 # 72

Which statement is true regarding savepoints?

• A. Static variables are not reverted during a rollback.
• B. Reference to savepoints can cross trigger invocations.
• C. You can roll back to any savepoint variable created in any order.
• D. Savepoints are not limited by DML statement governor limits.

正解：A

解説：
When rolling back to a savepoint, any DML operations that occurred after that savepoint are undone, but static variables are not reverted. Therefore, when a rollback occurs, the state of all static variables at the time of the rollback remains the same as it was just before the rollback.References: Apex Developer Guide - Savepoint and Transaction Control

質問 # 87
Universal Containers uses a custom Lightning page to provide a mechanism to perform a step-by-step wizard search for Accounts. One of the steps in the wizard is to allow the user to input text into a text field, ERF Number_c, that is then used in a query to find matching Accounts.

Which step should be taken to resolve the issue?

• A. Mark the ERP_Number__ c field as required.
• B. Move the SO0L query to within an asynchronous process.
• C. Mark the ERP_Numker = field as an external 10.
• D. Perform the SOQL query as part of a for loop.

正解：C

解説：
The step that should be taken to resolve the issue is to mark the ERP_Number__c field as an external ID. An external ID is a custom field that has the External ID attribute, meaning that it contains unique record identifiers from a system outside of Salesforce. When a field is marked as an external ID, Salesforce automatically indexes it and allows it to be used in filters, such as the WHERE clause in a SOQL query. This would improve the performance of the query and avoid the non-selective query exception. Performing the SOQL query as part of a for loop would not resolve the issue, as it would still hit the query limits and be inefficient. Marking the ERP_Number__c field as required would not resolve the issue, as it would not affect the query performance or the indexability of the field. Moving the SOQL query to within an asynchronous process would not resolve the issue, as it would still run into the same query limits and exception. Reference: [Custom Field Attributes], [Working with Very Large SOQL Queries]

質問 # 88
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?

• A. Static resources
• B. Custom metadata
• C. Custom settings
• D. system.Cookie class

正解：C

解説：
Custom settings are a type of custom data that can be used to store secret data with an ability to specify which profiles and users can access which secrets. Custom settings can store data in a hierarchical structure, which allows the developer to set different values for different levels of access, such as organization, profile, or user. Custom settings can also be encrypted using the Protected Custom Settings feature, which prevents the data from being exposed in the user interface, the API, or Apex code. By using custom settings, the developer can store the secret data securely and control the access to the data based on the user's profile or identity. Reference: [Custom Settings], [Protected Custom Settings]

• A. Publish the error event using the Eventbus. publish () method.
• B. Publish the error event with a Flow.
• C. Publish the error event using the addError method.
• D. No publishing is necessary. Have the external system subscribe to the BatchapexErrorEvent.

正解：D

質問 # 92
What are three reasons that a developer should write Jest tests for Lightning web components?
Choose 3 answers

• A. To verify the DOM output of a component
• B. To test how multiple components work together
• C. To test a component's non-public properties.
• D. To verify that events fire when expected
• E. To test basic user interaction

正解：A、C、E

解説：
Jest tests are essential for developing Lightning Web Components (LWC) because they allow developers to ensure the quality and correctness of their components in isolation from the rest of the application. Reason A is incorrect because testing non-public properties breaks encapsulation and is considered bad practice. B is correct because Jest tests can simulate user interactions with the component, such as clicking buttons or entering text, to ensure it behaves as expected. C is correct as well because Jest tests can confirm that the component renders the expected DOM output, which is crucial for ensuring that the HTML structure of the component is accurate. D is not the best choice since Jest is more suited for testing components in isolation rather than how multiple components interact; integration tests are more appropriate for that. Lastly, E is correct because Jest tests can verify that events are fired at the appropriate times, which is a critical part of the component's interaction with the rest of the application.
