Get Certified: Proven Methods to Pass the Salesforce CRT-450 Exam

To get the status of an enqueued job for a class that implements the Queueable interface, a developer can:

Option C: View the Apex Jobs page

Correct Answer.

Explanation:

The Apex Jobs page in Salesforce Setup lists all asynchronous Apex jobs, including queueable jobs.

Developers can view the status, start time, and completion time of the job.

In the provided class:

public class myClass {

public void myMethod() { /* implementation */ }

}

The class myClass is declared without any sharing keyword (with sharing, without sharing, or inherited sharing).

Default Sharing Behavior:

Apex classes without an explicit sharing declaration run in system context, meaning they do not enforce sharing rules.

Option B: Sharing rules will not be enforced for the running user.

Explanation: Since myClass does not specify with sharing, methods within it execute without enforcing sharing rules, allowing access to all data irrespective of the running user's sharing rules.

When using Lightning Data Service (LDS) in a Lightning Web Component (LWC), it's important to understand how data security is handled.

Option D: Lightning Data Service handles sharing rules and field-level security.

Correct Statement.

Explanation:

Lightning Data Service enforces all the security and sharing rules that are in place in the Salesforce org.

This includes object-level, field-level, and record-level security.

When a component uses LDS to access data, the framework ensures that the user only sees data they have access to.

Benefits:

Simplifies development by abstracting security checks.

Ensures compliance with organizational security policies.

The Lightning Component framework is used to develop:

Option B: Lightning Pages

Explanation: Lightning Components can be used to build custom components that can be added to Lightning Pages, enhancing the Lightning Experience and Salesforce mobile app.

To ensure that the Food_Preference__c picklist field has a value every time a record is created or updated, marking the field as Required on the field definition is the optimal solution.

Option C: Mark the field as Required on the field definition

Universal Enforcement: Setting the field as required at the field level ensures that it must have a value regardless of how the record is created or updated (UI, API, data import).

Data Integrity: Prevents records from being saved without a value in the picklist field, maintaining data consistency.

No Additional Code: Achieves the requirement declaratively without the need for Apex code.

To run a script that deploys to a sandbox:

Option A: VSCode

Explanation: Visual Studio Code with the Salesforce Extensions Pack allows developers to deploy code using scripts and integrates with Salesforce CLI.

Option D: SFDX CLI

Explanation: The Salesforce CLI (SFDX CLI) can be used to script deployments to any org, including sandboxes.

Example Command:

sfdx force:source:deploy -u sandboxAlias -p path/to/source

To create a custom user interface component that allows users to enter information about their accounts and validate user input before saving, the best technology is:

Option A: Lightning Web Components

Lightning Web Components (LWC):

LWC is a modern UI framework built on web standards, providing efficient performance and a rich set of base components.

Input Validation:

LWCs support client-side validation using standard HTML5 validation and custom validation logic.

Developers can use JavaScript to validate user input before saving data to the database.

User Experience:

LWCs provide a responsive and interactive user experience, which is essential for data entry components.
