質問 # 165
A developer implemented a custom data table in a Lightning web component with filter functionality. However, users are submitting support tickets about long load times when the filters are changed. The component uses an Apex method that is called to query for records based on the selected filters.
What should the developer do to improve performance of the component?
正解：B
解説：
When faced with performance issues in a Lightning Web Component (LWC) due to SOQL query load times, the optimal approach is often to improve the query's selectivity. This can be achieved by using a selective SOQL query with a custom index. Salesforce can create custom indexes to improve the performance of queries that cannot be optimized through standard indexing. When a query is selective, it can efficiently retrieve records from the database using the index, thus reducing the query execution time and speeding up the component's performance when filters are changed. The other options (returning all records, using SOSL, or client-side caching) do not directly address the root cause of the performance issue, which is the need for a more efficient database operation.

質問 # 166
A developer gets an error saying 'Maximum Trigger Depth Exceeded.'
What is a possible reason to get this error message?
正解：B
解説：
The "Maximum Trigger Depth Exceeded" error message is typically caused by a trigger being recursively invoked too many times. Salesforce has a limit on the depth of trigger recursion to prevent infinite loops, which is 16 times.
質問 # 167
A developer created a Lightning web component that uses a lightning-record-edit-form to collect information about Leads. Users complain that they only see one error message at a time about their input when trying to save a Lead record.
What is the recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention?
正解：B
解説：
Salesforce validation rules are declarative and can be used to validate more than one field on an object and display multiple error messages. This approach requires minimal JavaScript code and uses Salesforce's built-in validation framework. Reference:
Validation Rules
質問 # 168
A developer creates an application event that has triggered an infinite loop.
What may have caused this problem?
正解：D
解説：
The infinite loop in the application event could be caused by multiple handlers registered in the project. If the event is fired and then handled in such a way that the handling leads to the event being fired again, this can create a loop. Care must be taken to ensure that the handling of the event does not re-trigger the same event unintentionally.
質問 # 169
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?
正解：B
