Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer. Recently a record-triggered flow was added to update a date field. Since the addition of the flow, two Account Plan records are created. What might cause this to happen?

An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature. The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters. What is the optimal way to implement these requirements?12345

The Account object has a field, Audit_Code__c, that is used to specify what type of auditing the Account needs and a Lookup to User, Auditor__c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code__c. Each User in the org has a unique text field, Audit_Code__c, that is used to automatically assign the correct user to the Account's Auditor__c field.

Trigger:

Java

trigger AccountTrigger on Account (before insert) {

AuditAssigner.setAuditor(Trigger.new);

}

Apex Class:

Java

public class AuditAssigner {

public static void setAuditor(List accounts) {

for (User u : [SELECT Id, Audit_Code__c FROM User]) {

for (Account a : accounts) {

if (u.Audit_Code__c == a.Audit_Code__c) {

a.Auditor__c = u.Id;

}

}

}

}

}

What should be changed to most optimize the code's efficiency?
