Quick Answer
The answer is warranty. In ITIL 4, warranty is the aspect of service that assures the service will be available, secure, and have sufficient capacity and continuity—essentially, that it is “fit for use.” A guaranteed uptime of 99.9% and data encryption at rest are classic warranty components, so when a server outage makes the service unavailable, it directly violates the warranty promise. On the ITIL 4 Foundation exam, this distinction between warranty and utility is a frequent trap: utility covers what the service does (its functionality, or “fit for purpose”), while warranty covers how well it performs (availability, security, capacity, continuity). A common memory tip is to think of utility as the “what” and warranty as the “how well”—or simply remember that an outage always hits warranty first.
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 company offers a cloud storage service with a guaranteed uptime of 99.9% and data encryption at rest. A customer reports that the service is unavailable due to a server outage. According to ITIL 4, the service is failing to meet which aspect of service?
Output
Why wrong: Output is a deliverable, not relevant to service availability.
Utility
Why wrong: Utility is about functionality offered by the service. The outage is about availability, which is part of warranty.
Outcome
Why wrong: Outcome is a result for a stakeholder, not a service attribute.
Warranty
Warranty ensures the service is available, secure, and reliable. The outage impacts warranty.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Warranty
Warranty refers to the availability, capacity, continuity, and security (fit for use). Uptime guarantee and data encryption are warranty aspects. Utility refers to functionality (fit for purpose). Outcome is the result for stakeholders, and output is a deliverable. The outage affects warranty (availability).
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Output
Why it's wrong here
Output is a deliverable, not relevant to service availability.
Utility
Why it's wrong here
Utility is about functionality offered by the service. The outage is about availability, which is part of warranty.
Outcome
Why it's wrong here
Outcome is a result for a stakeholder, not a service attribute.
Warranty
Why this is correct
Warranty ensures the service is available, secure, and reliable. The outage impacts warranty.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
Output is a deliverable, not relevant to service availability.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A service provider is designing a new cloud storage service. The service is fast and secure, but it does not have a backup system. Which aspect of service is missing?
hardWhy D: Warranty covers availability, capacity, continuity, and security. A backup system is part of continuity (warranty). Utility is about functionality.
Variation 2. A cloud service provider offers a virtual server with 99.99% uptime guarantee. Which aspect of value does this guarantee primarily relate to?
mediumWhy A: Warranty is 'fit for use' and includes availability, capacity, continuity, and security. The uptime guarantee directly addresses availability, which is part of warranty. Utility is 'fit for purpose' (functionality). Option B is correct. Option A (Utility) would refer to what the service does, not its availability. Options C and D are not ITIL 4 value components.
