The error message 'Maximum trigger depth exceeded' occurs when a trigger invokes itself recursively more than the allowed limit.

Option C: The trigger is getting executed multiple times.

Correct Answer.

Explanation:

This error indicates that the trigger is recursively calling itself.

This can happen if the trigger performs an update or insert operation that causes the same trigger to fire again, leading to an infinite loop.

Salesforce enforces a limit on the recursion depth to prevent stack overflows.

Using Database.insert with allOrNone=false allows partial success in DML operations.

Option D: Use the Database method with allOrNone set to false.

Records that cause errors are not inserted.

Successful records are committed.

Prevents the entire batch from failing.

Why Not Other Options:

Option A: Deactivating the trigger is not practical.

Option B: Removing the class from the profile may cause other issues.

Option C: A try-catch block won't prevent the batch from failing.

To enable a custom event in a Lightning Web Component (LWC) to bubble up the containment hierarchy and cross the Shadow DOM boundary, the event must be dispatched with the properties:

bubbles: true

composed: true

bubbles Property:

When set to true, the event bubbles up through the DOM hierarchy, allowing parent components to listen for the event.

"The bubbles option indicates whether the event bubbles up through the DOM or not."— Lightning Web Components Developer Guide: Event Propagation

composed Property:

When set to true, the event can pass through the Shadow DOM boundary, allowing components outside the Shadow DOM to receive the event.

"The composed option controls whether the event can propagate across the boundary between the shadow DOM and the regular DOM."— Lightning Web Components Developer Guide: Event Composition

Example:

// ChildComponent.js

const event = new CustomEvent('myevent', {

bubbles: true,

composed: true,

detail: { /* event data */ }

});

this.dispatchEvent(event);

Why Other Options Are Incorrect:

Option B: bubbles: true, composed: false

The event will bubble up within the Shadow DOM but will not cross the Shadow DOM boundary.

Option C: bubbles: false, composed: false

The event will neither bubble nor cross the Shadow DOM boundary, limiting its propagation.

Option D: bubbles: false, composed: true

The event will not bubble up the containment hierarchy but can cross the Shadow DOM boundary, which is insufficient for the requirement.

Conclusion:

Setting both bubbles and composed to true ensures the event bubbles up through the component hierarchy and crosses the Shadow DOM boundary.

Option D: Use Test.getStandardPricebookId() to get the standard price book ID.

Correct Answer.

Explanation:

The Test.getStandardPricebookId() method returns the ID of the standard price book, which can be used in test classes without using SeeAllData=true.

This allows the test to access and use the standard price book in a controlled manner.

To allow partial success when inserting a list of records, the developer should use the Database class methods with the allOrNone parameter set to false.

Option B: Database.insert(records, false)

Correct Answer.

Explanation:

The Database.insert() method allows for partial processing.

By setting the second parameter (allOrNone) to false, the operation will attempt to insert all records.

If some records fail, the successful ones will be committed, and the errors can be examined from the result.

Usage:

Database.SaveResult[] results = Database.insert(records, false);

for (Database.SaveResult sr : results) {

if (sr.isSuccess()) {

// Record inserted successfully

} else {

// Handle errors

for (Database.Error err : sr.getErrors()) {

System.debug(err.getMessage());

}

}

}

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.

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
