Many-to-Many Relationship:

To track which companies (Accounts) report which bugs and allow multiple associations for both, ajunction objectis needed.

This junction object will have two master-detail relationships: one toBug__cand one toAccount.

Why Not Other Options?

A. Roll-up summary field: Not suitable for many-to-many relationships.

B. Master-detail field on Bug__c to Account: Creates a one-to-many relationship, not many-to-many.

C. Lookup field on Bug__c to Account: Still creates a one-to-many relationship, not many-to-many.

UsingSecurity.stripInaccessibleensures compliance with field-level security (FLS) and prevents users from accessing fields they do not have permission to view. In this scenario:

The commission field is inaccessible to Sales Assistants, andSecurity.stripInaccessiblewill automatically remove this field from the result set.

It prevents runtime errors when a user without proper access attempts to retrieve restricted fields.

Based on the provided code, an exception is likely being thrown if a required field is missing or if there are validation rules that the record does not meet. Salesforce will throw an exception when an attempt to create a record violates constraints.

Why not other options?

B: Salesforce reports errors for failed DML operations unless they are handled in atry-catchblock.

C: The record cannot be created successfully if constraints are violated.

D: Debug logs may provide details, but the record creation would fail.

Apex DML Exception Handling

The variableisOKis declared but not initialized, so its value isnull. Theif-elseconditions check for specific values ofisOK(trueorfalse), but since it isnull, none of those conditions are satisfied. The program defaults to theelseblock, assigning4tox.

Why Data Loader?

Data Loader supports all standard and custom objects, including Opportunities.

It is suitable for importing large data volumes like 500 records.

Why Not Data Import Wizard?

The Data Import Wizard does not support all objects, such as Opportunities.

Why Not Other Options?

A: Data Loader does not automatically relate Opportunities to Accounts unless provided external IDs.

B: Data Loader is a desktop application, not browser-based.

D: The Data Import Wizard can handle more than 500 records for supported objects, but it doesn't support Opportunities.

B: Using partial DML statements (e.g.,Database.insert(list, false)) allows only valid records to be committed while identifying invalid ones, avoiding runtime errors.

D: TheDatabase.Savepointmethod ensures transactional control by allowing rollback to a specific savepoint if an error occurs.

Why not other options?

A: The@ReadOnlyannotation is for read-only operations and would not allow DML operations.

C: TheSystem.Limitclass helps monitor limits but does not directly control transaction behavior.

Best Practices for Apex Transactions

Upload the SVG file as astatic resourcein Salesforce.

Import it in the LWC JavaScript file and define it as a property.

Reference the property in the component’s HTML template.

Example:

importmySvgfrom'@salesforce/resourceUrl/mySvg';

exportdefaultclassMyComponentextendsLightningElement{

svgUrl = mySvg;

}

Lightning Web Components Static Resources

In the context of the MVC (Model-View-Controller) architecture for a Lightning Web Component (LWC), the Apex class and JavaScript file are responsible for handling the controller's role:

Apex Class (Controller):

Acts as the server-side controller.

Executes business logic, such as the complex validations mentioned in the scenario.

Exposes methods for the LWC to call using@AuraEnabled.
