Final answer:
In system administration, the admin role often has significant permissions, but also has limitations and cannot perform all actions, such as granting certain specialized roles. The ability to delegate the admin role or modify admin groups typically is restricted to prevent security risks.
Step-by-step explanation:
When discussing the role of an admin in a system, it is important to understand the permissions and limitations associated with this title. The admin role typically allows a user to perform various privileged operations in a system or software environment.
Regarding the statements provided:
- Non-admin users cannot add a user to a group that contains the admin role.
- A user with only the admin role cannot grant the security_admin role to other users.
- Admin role can be delegated to non-admin users.
Correct answers from the provided options would depend on the specific system or software, but in general, there are safeguards in place like separating duties and restricting permissions to ensure system security. Therefore, statement b is usually true as specialized admin roles such as security_admin often require additional privileges. Statement c might be true depending on the software's delegation capabilities. Typically, non-admin users cannot alter admin groups or roles, supporting statement a.
