Quick Answer
The answer is Problem Management. This is the correct choice because ITIL 4 defines Problem Management as the practice specifically tasked with investigating the root cause of one or more incidents, particularly when a recurring pattern of errors is identified, as seen with the financial application. On the ITIL 4 Foundation exam, this question tests your ability to distinguish Problem Management from Incident Management—a common trap is confusing the two, since Incident Management focuses on restoring service quickly, not on deep root cause analysis. The exam often presents scenarios with repeated failures to see if you recognize that Problem Management must be initiated to prevent future occurrences. A helpful memory tip: think of Problem Management as the detective that asks “why” to stop the pattern, while Incident Management is the firefighter that just puts out the flames.
This ITIL4F practice question tests your understanding of itil management practices. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An IT team discovers a recurring pattern of errors in a financial application. According to ITIL 4, which practice should be initiated to investigate the root cause?
Problem Management
Correct: Problem Management focuses on root cause analysis.
Change Enablement
Why wrong: Incorrect: Change Enablement handles the authorization of changes, not investigation.
Service Request Management
Why wrong: Incorrect: Service requests are predefined requests, not investigations.
Incident Management
Why wrong: Incorrect: Incident Management restores service, not investigates root cause.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Problem Management
Problem Management identifies the root cause of incidents to prevent recurrence.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Problem Management
Why this is correct
Correct: Problem Management focuses on root cause analysis.
Related concept
Static NAT maps one inside address to one outside address.
Change Enablement
Why it's wrong here
Incorrect: Change Enablement handles the authorization of changes, not investigation.
Service Request Management
Why it's wrong here
Incorrect: Service requests are predefined requests, not investigations.
Incident Management
Why it's wrong here
Incorrect: Incident Management restores service, not investigates root cause.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ITIL4F NAT questions on configuration and troubleshooting.
