Apstra role-based access control separates fabric operations from identity and authorization administration. The administrator role includes full permissions, including the ability to manage users and roles (for example, creating users, assigning permissions, and creating/cloning/editing custom roles where allowed). This enables administrators to govern who can access the system and what they are permitted to change across all blueprints and system settings.

The user role, in contrast, is designed for day-to-day fabric work: viewing and editing supported blueprint elements and operational objects within the scope permitted by the role, but not administering other users’ access or modifying the role structure itself. In other words, a user can work on the network intent and operations, but cannot elevate privileges, change other users’ roles, or otherwise manage user/role administration unless explicitly granted additional permissions through custom roles.

That makes option C the correct statement: the user role cannot make changes to other user types (that is, it lacks the permissions needed to administer identities/roles). Options A, B, and D do not reflect Apstra’s RBAC model: roles are not primarily constrained “per blueprint” in that way, and users are not intended to modify other roles—those are administrator-level capabilities.
