How can a queue occur if utilization is less than 100%? It's because utilization is measured across some time interval. A queue forms when, at some point during this time interval, the resource is already busy (or all resources are already busy) and more work arrives. Then the new work must wait in a queue until the resource(s) finish(es) the old work. But at other times during the time interval, the resource(s) are not always busy. Let's say that utilization is less than 100% across some time interval. What is the utilization of the resource(s) during that portion of the time interval that a queue exists? Group of answer choices Definitely 100% Definitely less than 100%. Likely less than 100%, but we can't be sure. Likely 100%, but we can't be sure
