質問 # 152
Which code snippet processes records in the most memory efficient manner, avoiding governor limits such as "Apex heap size too large"?
A)
B) C)
D)
正解：B
解説：
Option D, which uses the Database.query() method in combination with a for loop, is the most memory-efficient way to process records. This is known as the Query Locator pattern, which allows you to work with a large number of records by querying them in batches. This approach helps to avoid hitting the governor limit for "Apex heap size too large" as it processes one record at a time from the database without storing the entire result set in memory.

As part of a custom interface, a developer team creates various new Lightning web components. Each of the components handles errors using toast messages. When the development is complete, all the components are added to the same Lightning page.
During acceptance testing, users complain about the long chain of toast messages that display when errors occur loading the components.
Which two techniques should the developer implement to improve the user experience?
Choose 2 answers
正解：B、D
解説：
The scenario describes a common issue when multiple components are used on the same Lightning page and each component manages its error handling independently, leading to a "long chain of toast messages" which can be overwhelming for users.
To improve user experience, the developers can implement the following techniques:
A . Use a Lightning web component to aggregate and display all errors: This method involves creating a centralized component responsible for handling all error messages. This component would receive error notifications from other components and then display them in a user-friendly manner. The benefit of this approach is that it provides a single, consistent interface for error messages, reducing the clutter and confusion that can be caused by multiple toasts.
D . Use public properties on each component to display the error messages: By using public properties, components can expose their error states to a parent or orchestrating component, which can then display these errors in a single, consolidated way. This avoids the issue of multiple toast notifications and allows for a more integrated error handling experience.
The other options presented are less ideal:
B . Using the window.alert() method is not recommended in a professional Salesforce environment as it is considered a disruptive way to show errors and does not align with the Salesforce Lightning design system.
C . Using a <template> tag to display in-place error messages could be a viable option for displaying error messages within the component itself, but it does not address the issue of multiple errors stacking up from different components as described in the scenario.

質問 # 154
Universal Containers is implementing a new approval process for expense reimbursements. The process requires complex logic to determine the appropriate approver based on factors such as expense amount, employee role, and project type. The solution should allow for flexibility and future changes in the approval rules.
Which approach would be the most suitable for implementing this logic?
正解：A
解説：
Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.
質問 # 155
A developer created a Lightning web component that uses a Lightning_record_edit_fom 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.
Which best practice should the developer use to perform the validations on more than one held, thus allowing more than one error message to be displayed simultaneously?
正解：A
解説：
When users need to see multiple error messages at a time related to their input on a form, client-side validation is the preferred method. This allows immediate feedback on the input fields without the need to submit the form to the server.
Option B (Client-side validation) is correct because it enables validation of multiple fields before submitting the form, allowing users to see all error messages at once for the fields that fail validation.
Options A (Apex REST), C (Custom validation rules), and D (Next Best Action) are not directly related to the validation of form inputs in the context of a Lightning web component.

質問 # 156
There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user.
The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, "Maximum view state size limit exceeded".
What step should the developer take to resolve this issue?
正解：C
解説：
To resolve the issue of the Visualforce page taking too long to display results or exceeding the view state limit, the developer should use a StandardSetController or implement SOQL LIMIT in the Apex controller. This limits the number of records that are processed and displayed at one time, which can prevent view state errors and improve performance.
