PDI Exam Dumps - Salesforce Developers Questions and Answers

To make an LWC available for use on a record page:

Target Configuration:

Add lightning__RecordPage in the component's .js-meta.xml file to specify where the component can be used.

Expose the Component:

Set isExposed to true in the .js-meta.xml file to make the component available for use.

Example .js-meta.xml File:

57.0

true

lightning__RecordPage

A: Incorrect placement. The tag must be in the .js-meta.xml file, not the JavaScript file.

D: The tag is used for metadata labeling, not for exposing or targeting a component.

Why Not the Other Options?References:

The requirement specifies that the Salary__c field should function as a currency input and honor field-level security.

The lightning-input-field component (Option C) automatically respects field-level permissions set in Salesforce and ensures the Salary__c field is editable and viewable only by authorized users.

Other options do not guarantee compliance with field-level security:

Option A: does not enforce field-level security.

Option B: is read-only and cannot be used for editing.

Option D: requires custom logic for enforcing security.

Field-Level Security Best Practices

Pagination using a StandardSetController helps manage large datasets by loading only a subset of records at a time. This approach minimizes view state size, which is critical for handling large datasets like 10,000+ records.

To check test coverage for autolaunched flows before deployment, developers need to use SOQL queries with the Tooling API. This provides detailed information about which flows are covered and their test results.

Option C implements a before insert trigger to prevent the creation of Request__c records when specific conditions exist. It uses the addError method to display an error to users.

Example of correct logic:

trigger RequestTrigger on Request__c (before insert) {

for (Request__c req : Trigger.new) {

if (!RequestLogic.isValid(req)) {

req.addError('Your request cannot be created at this time.');

}

}

}

To embed a Flow in an Aura component, the lightning:flow tag is used. It allows developers to interact with flows declaratively in Aura components.

 Option B: Escapes single quotes using String.escapeSingleQuotes, protecting against SOQL injection.

 Option C: Uses bind variables, which are inherently safe from SOQL injection.

Allow Reparenting in Master-Detail Relationships:

In a master-detail relationship, the child record (in this case, OrderItem) is tightly bound to the parent record (Order).

By default, child records cannot be reassigned to a different parent record in master-detail relationships. However, enabling the "Allow Reparenting" option on the master-detail field allows the child record (OrderItem) to be reparented to a different master record (Order).

This is the correct solution as it ensures that OrderItem records can be reassigned to a new Order without changing the structure of the relationship.

Why not the other options?

A. Add without sharing to the Apex class declaration:

Adding without sharing modifies sharing rules but does not affect the ability to reparent child records. This is unrelated to the issue described.

B. Change the master-detail relationship to an external lookup relationship:

Changing the relationship type is not necessary. Additionally, doing so could introduce unintended side effects, as master-detail relationships have features like roll-up summaries that are lost with a lookup relationship.

C. Create a junction object between OrderItem and Order:

Introducing a junction object is not required. This adds unnecessary complexity and deviates from the intended use of master-detail relationships.

Allow Reparenting Option

Option A: The Lightning Component Framework uses client-side rendering for improved performance and responsiveness.

Option B: Lightning components automatically adhere to accessibility standards (e.g., ARIA).

Option D: The framework allows for seamless integration with external libraries via JavaScript.

Not Suitable:

Option C: Lightning components are compatible with modern browsers but not all browsers.

Salesforce CLI allows developers to automate deployments and run unit tests as part of a continuous integration (CI) pipeline. It is the most efficient tool for scripting these processes.
