To fire an exception in Apex, the developer must use the throw statement along with an instance of the exception.

Option A: throw new ParityException();

Correct Way.

Creates a new instance of ParityException with no message and throws it.

Syntax is correct for throwing an exception.

Option C: throw new ParityException('parity does not match');

Correct Way.

Creates a new instance of ParityException with a custom message and throws it.

The exception class inherits from Exception, which allows passing a message to the constructor.

Options Not Correct:

Option B: new ParityException('parity does not match');

Incorrect.

This statement creates a new instance of ParityException but does not throw it.

Without the throw keyword, the exception is not fired.

Option D: new ParityException();

Incorrect.

Similar to Option B, this creates a new instance but does not throw it.

The exception will not affect the flow unless it is thrown.

Conclusion:

The two ways the developer can fire the exception are:

Option A: throw new ParityException();

Option C: throw new ParityException('parity does not match');

Both use the throw statement to fire the exception.

Change Sets are a point-and-click tool for migrating metadata between related Salesforce orgs, such as from a sandbox to a production org.

Option C: Deployment is done in a one-way, single transaction.

Correct.

Change sets are deployed in a one-way direction from the source org to the destination org.

The deployment occurs in a single transaction. If any component fails to deploy, the entire deployment is rolled back.

Before deploying a change set, you must set up a deployment connection between the source and destination orgs.

This connection is established through the Setup menu under Deployment Connections.

Change sets can only be sent between orgs that are affiliated, such as a sandbox and its production org, or sandboxes that are clones of the same production org.

They cannot be used between unrelated orgs.

Change sets can deploy the metadata of custom settings (the definition), but not the actual data stored within them.

To move custom settings data, you must use a data migration tool like Data Loader.

Change sets are designed to transfer metadata components, not data records.

To transfer data records, use tools like Data Loader or Data Import Wizard.

Deploy Change Sets

Option D: Sending a change set between two orgs requires a deployment connection.

Correct.

Create Deployment Connections

Option E: Change sets can only be used between related organizations.

Correct.

Change Sets Overview

Incorrect Options:

Option A: Change sets can deploy custom settings data.

Incorrect.

Change Set Considerations

Option B: Change sets can be used to transfer records.

Incorrect.

Deploy Metadata with Change Sets

Conclusion:

The three characteristics of change set deployments are C, D, and E.

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.

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.

Sharing only the Defect__c record is not enough; access to the Case is also required.

Option B: Share the parent Case record.

Insufficient.

Option D: Share the Case_Defect__c record.

*Not Possible Directly.

Sharing rules cannot be applied directly to junction object records in a master-detail relationship.

Access is controlled through the parent records.

Conclusion:

To share a specific Case_Defect__c record with a user, you need to share both the parent Case and Defect__c records, which is Option C.

Sharing Considerations for Junction Objects

Sharing Behavior

Incorrect Options:

Option A: Share the parent Defect__c record.

Insufficient.

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.

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

It acts as the server-side controller logic.

The JavaScript file of the LWC handles the client-side logic.

It invokes the Apex method when the button is pressed.

The HTML file defines the component's template (View), not the Controller.

Option B: XML file

Configuration File.

The XML file (configuration file) defines metadata about the component, such as where it's available, but it's not part of the Controller.

Conclusion:

The Controller parts in this scenario are the Apex class and the JavaScript file, which are Options C and D.

Calling Apex Methods

Option D: JavaScript file

Part of Controller.

JavaScript Controller in LWC

Incorrect Options:

Option A: HTML file

View Layer.
