Question 33
ObservabilityWhat is an SLO (Service Level Objective)?
Correct answer: B
Explanation
An SLO is the target you set for a service level indicator, defining the performance level a service should meet. It is often expressed as a measurable goal like "99.9% success over 30 days," which makes it an internal benchmark for reliability and availability.
Why each option is right or wrong
A. An external contract with penalties for failing to meet a promised service level
B. An internal target for a service level indicator, such as 99.9% success over 30 days
An SLO is the target value set for a service level indicator, not the indicator itself: in this case, the measurable goal is 99.9% success measured over a 30-day window. The 30-day period and 99.9% threshold make it an internal performance objective used to judge whether the service is meeting its reliability target.
C. A current measurement of how the service is performing right now
D. A monitoring dashboard used to visualize service metrics
