NEW QUESTION # 96
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
Answer: B,C,D
Explanation:
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.

NEW QUESTION # 97
A developer wrote a test class that successfully asserts a trigger on Account, It fires and updates data correctly In a sandbox environment.
A Salesforce admin with a custom profile attempts to deploy this trigger via a change set into the production environment, but the test class falls with an Insufficient privileges error.
What should a developer do to fix the problem?
Answer: C
Explanation:
When a test class fails with an "Insufficient privileges" error during deployment, it indicates that the user profile under which the tests are being executed doesn't have the necessary permissions to perform the actions required by the test. In a sandbox, the test might have been running with a different set of permissions compared to the production environment.
By using System.runAs(), you can specify a user context in which the test should run, which allows you to simulate the appropriate permissions. For this to work, you need to create a User instance in your test class with the profile that has the necessary permissions and then enclose the logic of your test within a System.runAs() block with this user.
This is a preferred solution over seeAllData=true, which would give the test access to all data in the production environment, potentially leading to tests that are not isolated and thus less reliable. It's also preferred over changing organization-wide settings or relying on specific setup in test classes, such as making sure Test.startTest() is not inside a loop.

NEW QUESTION # 98
A developer created a Lightning web component that uses a lightning-record-edit-form 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.
What is the recommended approach to perform validations on more than one field, and display multiple error messages simultaneously with minimal JavaScript intervention?
Answer: B
Explanation:
Salesforce validation rules are declarative and can be used to validate more than one field on an object and display multiple error messages. This approach requires minimal JavaScript code and uses Salesforce's built-in validation framework. Reference:
Validation Rules

NEW QUESTION # 100
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?
Answer: C
Explanation:
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.
