When you install a Configuration Manager site, several default site system roles are automatically installed for
the site.
These site system roles are required for the core operation of each site and although some default site system
roles can be moved to other servers, they cannot be removed from the site.
Which of the following is NOT a default role?

A.
Configuration Manager site system

B.
Enrollment point

C.
Configuration Manager site database server

D.
SMS Provider

Explanation:
Optional site system roles are site system roles that are not required for the core operation of a Configuration
Manager site. However, by default, the management point and distribution point, which are optional site system
roles, are installed on the site server when you install a primary or secondary site. Although these two site
system roles are not required for the core operation of the site, you must have at least one management point
to support clients at those locations.
