access control; Role-based access control makes it easier to administer access rights by changing
role membership and allowing for inheritance to grant permissions (instead of granting each

way to manage configurations for services and hardware. By centralizing this, it becomes easier
to push changes to multiple systems at once.

all that apply. ✔✔anonymous; Bind operations support three different mechanisms for
authentication: (1) Anonymous, which doesn't actually authenticate at all, and allows anyone to

Simple Authentication and Security Layer, which involves a secure challenge-response
authentication mechanism.
