Scheduling and Throttling on SCCM 2012 R2 DPs

Question

I read in a book that scheduling and throttling are only available on site systems with ONLY the DP site role installed. Does this mean that if I install the DP AND the SUP role on a server, then scheduling and throttling will NOT be available for the DP
role? 
How about if I setup a Secondary Site that has the MP and the DP role installed, will scheduling and throttling NOT be available for this scenario either?
Here is the excerpt from the book I am reading, titled "Mastering System Center 2012 R2 Configuration Manager" (from chapter 2: "Planning a Configuration Manager Infrastructure", page 42):
Scheduling and throttling are available only on site systems with only the distribution point site role installed. 
Thanks for any insight someone can offer

Answer 1

I think it's misinterpreted.

From Technet : The Rate
Limits and Schedule tabs
are displayed only in the properties for distribution points that are not installed on a site server.
That means that you cannot throttle on a Primary acting also as a DP.
Having SUP and DP will give you the option to throttle because it's not a "Site Server".

Site server
A computer from which you run Configuration Manager Setup and that provides the core functionality for the site.
