NEW QUESTION # 37
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: A,B
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 # 38
Universal Containers develops a Salesforce application that requires frequent interaction with an external REST API.
To avoid duplicating code and improve maintainability, how should they implement the APL integration for code reuse?
Answer: B
Explanation:
Creating a reusable Apex class for API integration allows for code encapsulation and maintainability. This class can then be invoked from any other Apex class that requires interaction with the API, preventing code duplication.
NEW QUESTION # 39
A developer creates a Lightning web component to allow a Contact to be quickly entered. However, error messages are not displayed.
Which component should the developer add to the form to display error messages?

NEW QUESTION # 40
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: A
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.
