Best ANSI options when creating a new database

Question

I am creating a new database on SQL Server 2012 for our production environment. When I use the "New Database ..." option from SQL Server Management Studio and generate the output, I get:

CREATE DATABASE [AAA]
 CONTAINMENT = NONE
 ON  PRIMARY 
( NAME = N'AAA', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQL2014\MSSQL\DATA\AAA.mdf' , SIZE = 5120KB , FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'AAA_log', FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQL2014\MSSQL\DATA\AAA_log.ldf' , SIZE = 1024KB , FILEGROWTH = 10%)
GO
ALTER DATABASE [AAA] SET COMPATIBILITY_LEVEL = 120
GO
ALTER DATABASE [AAA] SET ANSI_NULL_DEFAULT OFF 
GO
ALTER DATABASE [AAA] SET ANSI_NULLS OFF 
GO
ALTER DATABASE [AAA] SET ANSI_PADDING OFF 
GO
ALTER DATABASE [AAA] SET ANSI_WARNINGS OFF 
GO
ALTER DATABASE [AAA] SET ARITHABORT OFF 
GO
ALTER DATABASE [AAA] SET AUTO_CLOSE OFF 
GO
ALTER DATABASE [AAA] SET AUTO_SHRINK OFF 
GO
ALTER DATABASE [AAA] SET AUTO_CREATE_STATISTICS ON(INCREMENTAL = OFF)
GO
ALTER DATABASE [AAA] SET AUTO_UPDATE_STATISTICS ON 
GO
ALTER DATABASE [AAA] SET CURSOR_CLOSE_ON_COMMIT OFF 
GO
ALTER DATABASE [AAA] SET CURSOR_DEFAULT  GLOBAL 
GO
ALTER DATABASE [AAA] SET CONCAT_NULL_YIELDS_NULL OFF 
GO
ALTER DATABASE [AAA] SET NUMERIC_ROUNDABORT OFF 
GO
ALTER DATABASE [AAA] SET QUOTED_IDENTIFIER OFF 
GO
ALTER DATABASE [AAA] SET RECURSIVE_TRIGGERS OFF 
GO
ALTER DATABASE [AAA] SET  DISABLE_BROKER 
GO
ALTER DATABASE [AAA] SET AUTO_UPDATE_STATISTICS_ASYNC OFF 
GO
ALTER DATABASE [AAA] SET DATE_CORRELATION_OPTIMIZATION OFF 
GO
ALTER DATABASE [AAA] SET PARAMETERIZATION SIMPLE 
GO
ALTER DATABASE [AAA] SET READ_COMMITTED_SNAPSHOT OFF 
GO
ALTER DATABASE [AAA] SET  READ_WRITE 
GO
ALTER DATABASE [AAA] SET RECOVERY SIMPLE 
GO
ALTER DATABASE [AAA] SET  MULTI_USER 
GO
ALTER DATABASE [AAA] SET PAGE_VERIFY CHECKSUM  
GO
ALTER DATABASE [AAA] SET TARGET_RECOVERY_TIME = 0 SECONDS 
GO
ALTER DATABASE [AAA] SET DELAYED_DURABILITY = DISABLED 
GO
USE [AAA]
GO
IF NOT EXISTS (SELECT name FROM sys.filegroups WHERE is_default=1 AND name = N'PRIMARY') ALTER DATABASE [AAA] MODIFY FILEGROUP [PRIMARY] DEFAULT
GO

Why are so many ANSI options turned off by default? The server instance was configured by RackSpace on our behalf. Maybe due to some default settings set in the instance?

Thank you, Chris
