Final answer:
The LE Admin role granted by the Lifecycle Events application in ServiceNow is not automatically added to other roles; it is a standalone role that needs to be assigned manually by administrators.
Step-by-step explanation:
When the Lifecycle Events application is installed in ServiceNow, it grants the LE Admin role to a specific existing role within the ServiceNow hierarchy. The correct answer to which role the LE Admin role is granted is: 2) It is not added to other roles. Typically, in the context of ServiceNow, specific admin roles like LE Admin are standalone and are not automatically included with other roles due to the need for separation of duties and the granularity of permission sets within an organization. ServiceNow administrators can manually assign the LE Admin role to appropriate users based on the organizational structure and requirements.
