Carol is a new employee at ApTech Sol Inc.

Role-based access control (RBAC) is a model that assigns permissions and privileges to users based on their roles in an organization. In RBAC, the administrator defines the roles and the access rights for each role, and then assigns users to those roles. This way,the administrator can control the access of users to the resources without having to manage each user individually. In the scenario, Carol is assigned a role that does not have the installation rights, while the administrator has a role that does. Therefore, the access control model demonstrated in the scenario is RBAC.References:Network Defense Essentials - EC-Council Learning,Network Defense Essentials (NDE) | Coursera,EC-Council Network Defense Essentials | NDE Certification
