A developer is developing a reusable Aura component that will reside on an sObject Lightning page with the following HTML snippet:
How can the component"5 controller get the context of the Lightning page that the sObject is on without requiring additional test coverage?
By implementing force:hasSobjectName, the Aura component can retrieve the sObject context of the record page it is placed on without needing additional information. This interface provides the component with the API name of the sObject being displayed.

A developer needs to send Account records to an external system for backup purposes. The process must take a snapshot of Accounts as they are saved and then make a callout to a RESTful web service. The web service can only receive, at most, one record per call.
What should a developer do to implement these requirements?
A developer is building a complex commission calculation engine in Apex that is called from an Opportunity trigger. During QA it was reported that the calculations are incorrect.
The developer has representative test data and passing test methods in their developer sandbox.
Which three tools or techniques could the developer use to execute the code and pause it at key lines to visually inspect values of various Apex variables?
Choose 3 answers
To debug and troubleshoot the commission calculation engine, a developer can use several tools provided by Salesforce to inspect and pause the execution of Apex code.
Apex Interactive Debugger: It allows real-time debugging of Apex code execution. With this tool, a developer can set breakpoints, step through code, inspect variables, and evaluate expressions.
Developer Console: Although the Developer Console does not allow interactive debugging, it does provide the ability to view logs that capture the execution of code. Debug logs can be inspected to understand the flow of execution and values of variables at different points in time.
Apex Replay Debugger: This tool is part of Salesforce Extensions for Visual Studio Code. It allows a developer to replay a debug log as if they are stepping through the code line by line, which can be very useful to inspect the state of variables at specific points in the execution.

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
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.
For building a centralized error handling component: Lightning Web Components Developer Guide - Error Handling
For implementing public properties: Lightning Web Components Developer Guide - Public Properties
Refer to the test method below''
The test method calls a web service that updates an external system with Account
information and sets the Accounts integration_Updated__c checkbox to True when it completes.
The test fails to execute and exits with an error: "Methods defined as TestMethod do
not support Web service callouts.''
A)
B)
C)
D)
The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the method invocation, and finally Test.stopTest(). This ensures the mock callout is used. Reference: Apex Developer Guide - Testing HTTP Callouts
