- A
Upgrade to a more powerful database server with more CPUs.
Why wrong: This is expensive and may not solve the root cause if queries are inefficient; the issue may recur as traffic grows.
- B
Analyze and optimize the slow database queries identified by the database administrator.
This addresses the root cause directly, aligns with 'Focus on value' and 'Optimize and automate', and is cost-effective.
- C
Implement a caching layer to reduce database load.
Why wrong: Caching can help, but it is a band-aid solution that may not address inefficient queries and could increase complexity.
- D
Hire a database consultant to review the entire database architecture.
Why wrong: This could be costly and time-consuming; a quicker, focused optimization of specific queries is more practical.
Quick Answer
The correct course of action is to analyze and optimize the slow database queries identified by the database administrator. This choice directly addresses the root cause of the performance issue—inefficient queries causing high CPU load—rather than treating the symptom with costly hardware scaling. By applying the ITIL guiding principle of 'Focus on Value,' the team solves the actual problem while respecting the limited budget, since query optimization typically requires only DBA time instead of expensive infrastructure upgrades. On the ITIL 4 Foundation exam, this scenario tests your ability to distinguish between addressing a root cause versus a symptom, a common trap where candidates mistakenly choose to scale resources. Remember the memory tip: "Optimize before you upsize"—always look for the underlying inefficiency first when applying ITIL guiding principles to performance problems.
ITIL4F ITIL Service Value System Practice Question
This ITIL4F practice question tests your understanding of 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.
A large e-commerce company is experiencing slow response times on its website during peak shopping hours. The IT team has identified that the database server is under high CPU load. They have tried scaling up the server resources, but the issue persists. The team suspects that inefficient database queries are the cause. The service owner wants to implement a solution that aligns with the ITIL guiding principles. The company has a limited budget for this initiative. Which course of action should the team take to address the problem most effectively?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Analyze and optimize the slow database queries identified by the database administrator.
Option B is correct because the root cause is inefficient database queries, not insufficient hardware. Optimizing queries directly addresses the high CPU load by reducing the processing required per query, aligning with the ITIL guiding principle of 'Focus on Value' by solving the actual problem without unnecessary expenditure. This approach also respects the limited budget, as query optimization typically requires only DBA time rather than costly infrastructure upgrades.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume scaling up hardware (Option A) is always the answer to performance issues, but ITIL emphasizes solving the root cause first, and the question explicitly states that scaling up has already failed.
Detailed technical explanation
How to think about this question
Inefficient queries often cause high CPU load due to full table scans, missing indexes, or poor join strategies that force the database engine to process large row sets in memory. Tools like `EXPLAIN ANALYZE` in PostgreSQL or `SHOW PROFILE` in MySQL can pinpoint exactly which queries consume the most CPU and how to rewrite them or add appropriate indexes. In a real-world scenario, a single missing index on a foreign key column can turn a nested-loop join into a sequential scan, spiking CPU to 100% even on a modestly sized table.
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.
