The following statements about OCI burstable instances areNOT correct:
* A. Burstable instances cost less than regular instances:This is incorrect because burstable instances are not necessarily cheaper; the cost depends on the baseline utilization. While they allow for cost efficiency when running at a lower CPU baseline, they can become more expensive if frequently bursting above the baseline.
* B. Burstable instances are charged according to the baseline OCPU:This is incorrect because burstable instances are billed based on actual OCPU usage, which includes both baseline and burst usage. If an instance frequently operates above its baseline, the cost will reflect this higher usage.
Correct Concepts:
* C.Burstable instances can temporarily use more CPU than their baseline if the average CPU utilization is below the baseline.
* D.Baseline utilization is a fraction of each CPU core, which determines the level of consistent performance available without bursting.
