A company has a custom object. Order__c, that has a custom picklist field. Status__c, with values of New, In Progress," or Fulfilled and a lookup field, Contact_c, to Contact.
Which SOQL query wrii return a unique list of all the Contact records that have no Fulfilled Orders?

@isTest static void testAccountUpdate() { Account acct = new Account({Name = 'Test'); acct.Integration Updated_c = false; insert acct; CalloutUtil.sendAccountUpdate (acct.Id); Account acctAfter = [SELECT Id, Integration Updated_c FROM Account WHERE Id = :acct.Id] [0]; System.assert(true, acctAfter.Integration_Updated_c); } The test method above calls a web service that updates an external system with Account information and sets the Account's Integration_Updated__c checkbox to True when it completes. The test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web service callouts." What is the optimal way to fix this?

A developer needs to send Account records to an external system for backup purposes. The process must take a snapshot of Accounts as they are saved and then make a callout to a RESTful web service. The web service can only receive, at most, one record per call.
Which feature should be used to implement these requirements?

A developer created three Rollup Summary fields: Total_timesheets_c, Total_Approved_timesheet_c and Total_project_Timesheet_c in the custom object, project _c Now, the developer is tasked with created a new field to show the ratio between and approved

A developer has been asked to create code that will meet the following requirements:
Receives input of: Map<ld, Project_c), List<Account>
Performs a potentially long-running callout to an outside web service
Provides a way to confirm that the process executed successfully
Which asynchronous feature should be used?
