In ServiceNow, access to applications is controlled by roles. Most applications, such as Incident, Change, and Facilities, require specific roles to access them. However, the Self-Service application is available to all users, including those with the base "ess" (Employee Self-Service) role, which is assigned to every user by default.
Why "D. Self-Service" is the correct answer?
The Self-Service application is designed for general users (end users, employees, customers) who do not have elevated permissions. It provides access to:
The Service Catalog (to request IT services, software, and hardware).
The Knowledge Base (to search for articles and solutions).
Viewing and tracking submitted requests and incidents.
Submitting new incidents or requests.
Since it is meant for all users, it does not require any additional roles beyond the default ones given to employees or customers.
Explanation of Incorrect Options:
A . Change - Incorrect. The Change Management application is typically restricted to ITIL users (users with the itil role) and change managers. End users do not have access to this module.
B . Incident - Incorrect. While end users can create and view their own incidents via Self-Service, the Incident Management module itself is restricted to IT support staff (users with the itil role or higher).
C . Facilities - Incorrect. The Facilities application, which includes asset tracking and work orders, is typically restricted to users managing physical assets or facility-related tasks. It is not available to all users by default.
