ITIL4F The ITIL Service Value System Practice Question
This ITIL4F practice question tests your understanding of the itil service value system. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
You are the IT service manager for a medium-sized e-commerce company that processes online orders. The company uses a three-tier application architecture: a web server, an application server, and a database server. Recently, the company has been experiencing intermittent service degradation during peak hours (12:00-14:00 and 18:00-20:00), causing slow page loads and occasional timeouts. The monitoring system shows that CPU utilization on the application server spikes to 95% during these periods, while the web server and database server remain below 60%. The incident management team has been opening multiple tickets for the same issue, but each ticket is resolved by restarting the application server, which temporarily restores performance. The problem management team has been assigned to investigate the root cause. They have discovered that a recent software update to the application introduced a memory leak that gradually consumes resources until the server becomes overloaded. The development team has identified a fix but needs two weeks to fully test and deploy it. Meanwhile, the business is losing revenue due to poor performance. Which of the following actions should the problem management team take FIRST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement a workaround, such as scheduling a restart of the application server every hour during peak times.
Option B is correct because the problem management team should first implement a workaround to restore service and minimize business impact while the permanent fix is being developed. Restarting the application server every hour during peak times directly addresses the memory leak symptom by freeing accumulated memory, preventing CPU saturation at 95% and avoiding timeouts. This aligns with ITIL 4's guidance to apply a workaround as an interim measure when a known error exists and a fix is pending.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Conduct a root cause analysis to fully understand the memory leak.
Why it's wrong here
While RCA is important, the immediate priority is to reduce business impact; the leak is already known.
✓
Implement a workaround, such as scheduling a restart of the application server every hour during peak times.
Why this is correct
This provides a temporary fix to maintain service stability until the permanent fix is deployed.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the application server's CPU capacity to handle the load.
Why it's wrong here
Adding capacity may delay the impact but does not fix the memory leak; the issue will recur.
✗
Escalate the incident to the service desk for faster resolution.
Why it's wrong here
The service desk cannot fix the memory leak; escalation would not resolve the issue.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose Option A (root cause analysis) because they confuse the problem management process with incident management, failing to recognize that the root cause is already known and the priority is to restore service with a workaround first.
Detailed technical explanation
How to think about this question
A memory leak occurs when the application fails to release heap memory after use, causing the garbage collector in languages like Java or .NET to run more frequently and consume CPU cycles, eventually leading to OutOfMemoryError and server thrashing. Scheduling a restart forces a full garbage collection and resets the heap, but it is a temporary measure—the leak will reoccur until the code fix is deployed. In real-world scenarios, monitoring tools like JConsole or VisualVM can track heap usage over time to confirm the leak pattern.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the ITIL4F exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
