Parameters
-All
Indicates that this cmdlet gets all of the option definitions on the DHCP server service including vendor specific option definitions.

-AsJob
Runs the cmdlet as a background job.

You can continue to work in the session while the job completes.
To manage the job, use the *-Job cmdlets.
To get the job results, use the Receive-Job cmdlet.
