Which role is the minimum required to read and update incident records?
The itil role grants the read and update permissions required for incident records, making it the minimum role that satisfies both operations. Roles such as admin or sn_incident_write exceed this requirement, while read-only roles cannot update records.
Why this answer
The itil role in ServiceNow is the minimum role that grants read and write access to incident, problem, and change records. It is designed for ITIL process users such as service desk agents who need to work on incidents daily. The user role alone cannot update incidents, and admin/itil_admin are higher-privileged than required.
Exam trap
CIS-ITSM often tests the difference between 'user' (self-service only) and 'itil' (process user), and candidates incorrectly assume the base user role can update incidents.
How to eliminate wrong answers
Option A is wrong because the base 'user' role only grants access to self-service and basic record viewing — it cannot read or update incident records belonging to other users. Option C is wrong because 'admin' is a full system administrator role with far more privileges than needed, so it is not the minimum. Option D is wrong because 'itil_admin' is a role that combines ITIL process access with administrative capabilities over ITIL tables, which exceeds the minimum required to simply read and update incidents.
