How to invoke a SQL job from another Job present on a different instance

For invoking an SQL Server Job from another Job which is present on a different instance, we have different ways like

1. Create a Linked server and use msdb..sp_start_job to start the job
2. Using xp_cmdshell
3. Using SQLCMD Operating system command

In most of the SQL Server instances the xp_cmdshell will be disable due to security reasons and creating linked server is time consuming.
