NEW QUESTION # 140
Universal Containers stores user preferences in a Hierarchy Custom Setting, User_Prefs_c, with a Checkbox field, Show_Help_c. Company-level defaults are stored at the organizational level, but may be overridden at the user level. If a user has not overridden preferences, then the defaults should be used.
How should the Show_Help_c preference be retrieved for the current user?
Answer: B
Explanation:
To retrieve the Show_Help__c preference for the current user from a hierarchy custom setting, the getInstance() method should be used. This method retrieves the custom setting data for the user or the organization default if no user-specific setting is found.
NEW QUESTION # 141
Universal Containers is using a custom Salesforce application to manage customer support cases. The support team needs to collaborate with external partners to resolve certain cases. However, they want to control the visibility and access to the cases shared with the external partners. Which Salesforce feature can help achieve this requirement?
Answer: B
Explanation:
Apex managed sharing is the correct feature to control the visibility and access to cases shared with external partners. It allows developers to programmatically create sharing records that grant access to users based on specific criteria, providing granular control over record sharing.
NEW QUESTION # 142
Consider the following code snippet:
A developer created the following test class to provide the proper code coverage for the snippet above:
However, when the test runs, no data is returned and the assertion fails. Which edit should the developer make to ensure the test class runs successfully?
Answer: C
Explanation:
To ensure that the test class for a search functionality in Salesforce runs successfully, the developer should use the Test.setFixedSearchResults() method. This allows the test to specify the records that are returned by the search, ensuring that the search behavior is predictable and that the assertion can be properly evaluated.
NEW QUESTION # 143
The head of recruiting at Universal Containers (UC) wants to provide all internal users the ability to search for open positions by role, department, and location via a new recruiting app. In addition to search, users of the app should be able to refer a friend, apply for a position, and review the status of their current submissions.
The app will be surfaced to UC's existing iOS and Android users via the standard mobile app that Salesforce provides. It has a custom user interface design and offline access is not required.
Given these requirements, what is the recommended approach to develop the app?
Answer: C
NEW QUESTION # 144
A developer created an Apex class that updates an Account based on input from a Lightning web component that Is used to register an Account. The update to the Account should only be made if it has not already been registered.
What should the developer do to ensure that users do not overwrite each other's updates to the same Account if they make updates at the same time? A)
B)
C)
D)
Answer: B
Explanation:
When multiple users are updating the same record at the same time, there is a risk of overwriting each other's changes. Salesforce provides a mechanism called 'record locking' to prevent this from happening.
Option D is correct because including FOR UPDATE in the SOQL query locks the retrieved records for the duration of the transaction. This prevents other transactions from updating the record until the current transaction is complete, which is essential for avoiding race conditions where two users might overwrite each other's updates.
Option A is incorrect because while adding a try/catch block around the update operation is good practice for handling exceptions, it does not prevent overwrites from concurrent updates.
Option B is incorrect because using upsert instead of update does not address the problem of concurrent updates. The upsert operation is used to either insert a new record or update an existing one based on whether a record with a matching ID or external ID already exists.
Option C is incorrect because FOR UPDATE should be used in the SOQL query to lock the records, not in the SELECT statement itself.
