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

Option D: VS Code

Correct Answer.

Explanation:

Visual Studio Code with the Salesforce Extension Pack is the recommended IDE for developing and fixing Lightning Web Components.

It provides features like syntax highlighting, IntelliSense, debugging, and seamless deployment to a sandbox.

To check the code coverage of a class after running all tests, a developer can use the Developer Console.

Option B: View the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab.

Correct Method.

Explanation:

In the Developer Console, navigate to the Tests tab.

After running tests, the Overall Code Coverage panel displays code coverage statistics.

You can see the coverage percentage for individual classes.

To send an outbound message when a record meets specific criteria without using Apex code, we can use features that support outbound message actions.

Option B: Approval Process can be used to check the record criteria and send an outbound message without Apex code.

Correct Feature.

Explanation:

An Approval Process can include outbound message actions.

When a record enters a specific step of the approval process, an outbound message can be sent.

Criteria can be defined to determine when the approval process starts.

In the Model-View-Controller (MVC) architecture applied to a Lightning Web Component (LWC) that imports an Apex method:

Controller refers to the logic that handles input and interactions.

In this scenario, when a button is pressed, the method runs to execute complex validations.

Option C: Apex class

Part of Controller.

Explanation:

The Apex class contains the method that performs the complex validations.

It acts as the server-side controller logic.

To perform DML operations that insert new records and update existing records in a list of Order__c records using the external ID field Order_Number__c, you should use:

Option D: upsert orders Order_Number__c;

Upsert Statement:

The upsert DML operation either inserts or updates records based on whether they already exist.

By specifying the external ID field (Order_Number__c), Salesforce will match existing records based on this field.

Syntax:

upsert orders Order_Number__c;

orders is the list of Order__c records.

Order_Number__c is the external ID field used for matching.

Option A: Data Import Wizard does not support Opportunities.

Explanation: The Data Import Wizard supports importing data for certain standard objects (Accounts, Contacts, Leads, Solutions, Campaign Members, and Person Accounts) and custom objects. It does not support importing data into all standard objects like Opportunities.

Since Case and Defect__c have Private organization-wide defaults (OWD), users need explicit access to the parent records to access the child records in a master-detail or junction object relationship.

The Case_Defect__c is a junction object between Case and Defect__c.

Option C: Share the parent Case and Defect__c records.

Correct Answer.

Explanation:

To access a record on a junction object (Case_Defect__c), a user must have access to both parent records.

Sharing both the Case and Defect__c records with the user will grant them access to the Case_Defect__c record.

When a developer is alerted to an issue with a custom Apex trigger causing records to be duplicated, the most appropriate debugging approach is to add System.debug statements to the code.

Option A: Add System.debug statements to the code to track the execution flow and identify the issue

Trace Execution Flow: System.debug statements help log the values of variables and the execution path.

Identify Logic Errors: By examining the debug logs, the developer can pinpoint where the duplication is occurring.

Minimal Impact: Adding debug statements is a minimal code change and does not alter the functionality.

A polymorphic lookup field is a special type of lookup relationship field that can reference multiple object types.

Option C: The WhatId field on the standard Event object

Correct Answer.

Explanation:

The WhatId field on Event (and Task) can refer to multiple types of objects, such as Account, Opportunity, Custom Objects, etc.

This makes WhatId a polymorphic lookup field.
