What does an instant vector contain in PromQL?
- AOne sample per series at a single point in time
- BA range of samples per series over a time window
- CA single scalar number with no associated series
- DA string literal value used inside a label match
Why this is the answer
An instant vector holds one sample for each matching series at one timestamp. A range vector instead holds many samples per series across a time window.
