ITIL4F ITIL Service Value System Practice Question
An IT department is asked to deploy a critical security patch that must be implemented within 2 hours to address a zero-day vulnerability. The patch has been tested and approved for emergency use. According to ITIL 4, what type of change should be raised?
⚠ Common exam trap
It's easy for candidates to confuse a standard change (pre-authorized for low-risk tasks) with an emergency change, failing to recognize that the 2-hour urgency and zero-day severity mandate the emergency change process, not a standard or normal change.

Correct answer & explanation
✓
Emergency change
An emergency change is required because the zero-day vulnerability demands immediate deployment of a critical security patch within 2 hours to mitigate an active threat. ITIL 4 defines an emergency change as one that must be implemented as soon as possible, often to resolve a major incident or security breach, and it follows a streamlined process with pre-approved authorization (e.g., via an emergency change advisory board). The patch has been tested and approved for emergency use, confirming it meets the criteria for this change type.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Standard change
Why it's wrong here
Standard changes are pre-authorized, low-risk, and routine activities that follow a well-established procedure, often automated or self-service. A critical security patch, especially one addressing a newly discovered or zero-day vulnerability, inherently carries significant risk and urgency, making it unsuitable for pre-approval as a standard change without specific, prior assessment and authorization for that particular threat. Such a patch requires a more rigorous, albeit expedited, approval process due to its potential impact.
- ✗
Service request
Why it's wrong here
A service request is a formal request from a user for something that is a standard part of service delivery, typically pre-defined, pre-approved, and often fulfilled through self-service catalogs. Deploying a critical security patch, however, is an operational activity initiated by the IT department to maintain the integrity, availability, and security of services, not a user-initiated request for a standard service offering. Therefore, it does not fit the definition or purpose of a service request.
- ✗
Normal change
Why it's wrong here
Normal changes require a full assessment, planning, and authorization process, often involving a Change Advisory Board (CAB) to evaluate risk, impact, and resource allocation before implementation. This structured approach, designed for planned, non-urgent modifications, typically takes a significant amount of time, making it impractical for a critical security patch that needs deployment within a very short timeframe, such as two hours. The deliberate, multi-step process of a normal change would prevent the necessary rapid response.
- ✓
Emergency change
Why this is correct
An emergency change is specifically designed for urgent situations where immediate action is required to restore service, mitigate a critical security threat, or address a major incident that poses a significant risk to the organization. A critical security patch, particularly one addressing a severe vulnerability that could lead to data breaches or service outages, falls squarely into this category, necessitating an expedited assessment and authorization process to ensure rapid deployment and minimize potential damage. This change type prioritizes speed to protect organizational assets and maintain business continuity.
