NEW QUESTION # 90
A corporation has many different Salesforce orgs, with some different objects and some common objects, and wants to build a single Java application that can create, retrieve, and update common object records in all of the different orgs.
Which method of integration should the application use?
Answer: D
Explanation:
The SOAP API with the Partner WSDL is ideal for building integrations that work across multiple Salesforce orgs, especially when they have varying schemas. The Partner WSDL is designed to be flexible and dynamic, catering to different metadata.
NEW QUESTION # 91
Refer to the Lightning component below:
The Lightning Component allows users to click a button to save their changes and then redirects them to a different page. Currently when the user hits the Save button, the records are getting saved, but they are not redirected. Which three techniques can a developer use to debug the JavaScript? Choose 3 answers
Answer: A,C,E
Explanation:
When debugging JavaScript in a Lightning Component, developers can utilize the following techniques:
A . Use console.log() messages in the JavaScript: This is a standard debugging technique to log information to the browser console, which can help trace the execution flow or output variable values.
B . Use the browser's dev tools to debug the JavaScript: Modern browsers come equipped with developer tools that can be used to set breakpoints, step through code, and inspect variables at runtime.
C . Enable Debug Mode for Lightning components for the user: Enabling Debug Mode for users provides more detailed error messages and unminified versions of client-side libraries, making it easier to debug issues.
Using the Developer Console to view checkpoints (Option D) and debug logs (Option E) is more relevant for Apex debugging rather than JavaScript.

NEW QUESTION # 92
Salesforce users consistently receive a "Maximum trigger depth exceeded" error when saving an Account. How can a developer fix this error?
Answer: A
Explanation:
A common solution to the "Maximum trigger depth exceeded" error is to use a static variable in a helper class. The variable acts as a switch to ensure the trigger logic only executes once per transaction, preventing recursive trigger calls.
NEW QUESTION # 93
A developer wrote the following method to find all the test accounts in the org:
What should be used to fix this failing test?
Answer: C

NEW QUESTION # 94
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.
