Salesforce Developer Fundamentals Quiz

Developer Fundamentals

• Use Opportunity.sobjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.
• @AuraEnabled annotation allows to create Apex classes that can be called from Lightning web components
• public class CheckPaymentProcessor implements PaymentProcessor { public void pay (Decimal amount); } - This code implements the PaymentProcessor interface and creates a method named pay.
• @TestVisible annotation makes a method accessible to the test class.
• To create a currency input field that is viewable and editable only for users with the correct field level permissions use: <lightning-input-field field-name="salary_c"></lightning-input-field>.

Apex Fundamentals

• Ensure that the Account object has a master-detail relationship to the Branch object.
• Triggers fire multiple times during a transaction.
• Duplicate rules are executed once all DML operations commit to the database.

Process Automation

• Use Test.getStandardPriceBookId() to get the standard price book ID.
• Use an aggregate function in a trigger on the Opportunity object to calculate a roll-up summary from a custom object that is not in a master-detail relationship.

User Interface

• Use a Standard Controller with a Custom List Controller extension in order to allow users to edit multiple records at once.

Testing

• Use the BISTest (SeeAllData=true) method allows access to the standard price book.

Salesforce Development Life Cycle

• Full Sandbox is ideal to create the same configuration as the production org for a team of developers working on their individual orgs.
• Ensure the PrimaryId_c custom field on the Candidate_c custom object is marked as an External Id.
• Trigger execution can affect by before insert, after insert, before update, after update trigger events.
• DML operations are going to be rolled back after debuging a flow is ended.

Lightning Web Components

• fire() method is used to fire an event in Aura application events.
• When using the Batchable interface the Apex governor limits are reset for each iteration of the execute() method.
• To troubleshoot performance issues when a custom page loads, use System.debug().
• Universal Containers can use Custom objects and fields, Roll-up summaries, and Relationships to build out the database layer for a Salesforce application.
• Callouts to external systems are not executed when debugging a flow.
• The developer should create a Screen-based flow to implement the functionality for a service agent to process damaged or stolen credit cards.
• To create an account, the developer uses Account myAccount = new Account(Name = 'MyAccount'); to create an account object, then insert myAccount; inserts it into the database.
• The loop using the do..while statement executes 9 times.
• The loop creates 9 new accounts and inserts them into the database with names like 'New Account 1', 'New Account 2', etc.
• There are 16 total accounts in the org, since the developer started with 5 and created 10 more.
• The final account created is named New Account 10. The loop code increment the x variable up to 10 after each iteration. Therefore, the loop will execute 9 times (10 - 1 = 9), creating 9 new accounts.
