NEW QUESTION # 119
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
Answer: B,D
Explanation:
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.

NEW QUESTION # 120
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?
Answer: D
Explanation:
A StandardSetController or a SOQL LIMIT clause can be used to limit the number of records displayed at a time in a Visualforce page, and improve the performance and user experience of the page. A StandardSetController is a class that allows the developer to create list controllers, which can display a set of records using pagination, filtering, sorting, and other features. A SOQL LIMIT clause is a keyword that can be used to specify the maximum number of records to return from a query. By using either of these methods, the developer can reduce the amount of data that is transferred and processed by the page, and avoid the view state error, which occurs when the size of the view state exceeds the limit of 135 KB. Reference: [StandardSetController Class], [SOQL LIMIT Clause], [View State]
