ITIL4F Key Concepts of IT Service Management Practice Question
A user reports that the corporate email system is slow. The service desk agent troubleshoots and identifies that a recent update to the mail server caused high CPU usage. The agent restarts the mail server service, which resolves the issue. What is the user's report considered in ITIL 4?
⚠ Common exam trap
Many candidates confuse an incident with a problem, where the problem is the cause (high CPU usage) and the incident is the user-facing symptom (slow email).

Correct answer & explanation
✓
An incident
In ITIL 4, an incident is defined as an unplanned interruption to a service or reduction in the quality of a service. The slow email system represents a reduction in quality, and the user's report triggers incident management. A service request is a planned request, while a problem is the underlying cause of incidents, and a known error is a problem with a documented root cause and workaround. Thus, the report is an incident.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A known error
Why it's wrong here
A known error is a problem that has been analyzed and has not been resolved. The scenario does not indicate that the cause has been analyzed and documented as a known error; the agent simply resolved the incident by restarting the service, so it is not a known error.
- ✗
A problem
Why it's wrong here
A problem is a cause, or potential cause, of one or more incidents. While the high CPU usage could be a problem, the user's report itself is the incident. The problem would be the underlying cause that needs investigation to prevent recurrence, but the report of slowness is the incident.
- ✗
A service request
Why it's wrong here
A service request is a request from a user or user's authorized representative that initiates a service action which has been agreed as a normal part of service delivery. The slow email is not a pre-agreed request like a password reset; it is an unplanned degradation, so it is not a service request.
- ✓
An incident
Why this is correct
An incident is an unplanned interruption to a service or reduction in the quality of a service. The slow email system is a reduction in service quality, which the agent restores by restarting the service. This matches the definition of an incident, which is the correct term for such a report.
