To find the current user's default record type for Opportunity, the developer can use the DescribeSObjectResult and RecordTypeInfo classes.

Option A: Use Opportunity.SObjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.

Correct Approach.

Explanation:

// Get describe result for Opportunity

Schema.DescribeSObjectResult oppDescribe = Opportunity.SObjectType.getDescribe();

// Get list of RecordTypeInfo

List recordTypeInfos = oppDescribe.getRecordTypeInfos();

// Iterate through RecordTypeInfo to find the default one

Id defaultRecordTypeId;

for (Schema.RecordTypeInfo rtInfo : recordTypeInfos) {

if (rtInfo.isAvailable() && rtInfo.isDefaultRecordTypeMapping()) {

defaultRecordTypeId = rtInfo.getRecordTypeId();

break;

}

}

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.

Explanation:

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.

Explanation:

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.

Explanation:

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.

Explanation:

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.

Scratch Orgs are disposable Salesforce orgs that can be created quickly and configured with different features and settings. They are ideal for source-driven development and allow developers to work independently.

Option D: Scratch orgs

Correct Answer.

Scratch orgs support source-driven development and can be fully configured through scripts and the Salesforce CLI.

Developers can create and destroy scratch orgs as needed, ensuring they have isolated environments.
