問題文
An Exascale VM cluster will carry a workload whose busy hours arrive without much warning, and the team wants those hours served with steady performance. On the creation page the engineer opens the optional section for reserving capacity and asks what it buys and what values it takes. What should the architect say?
選択肢
- It holds the capacity for a machine in advance, which removes the delay of allocation and steadies its performance while the field that takes it accepts 0 through 192 in steps of 4.
- It sets the enabled count per virtual machine above its ceiling of 200 and the value that it takes runs from 8 to 200 in increments of 4, which the form checks.
- It sets capacity aside for the storage vault so that the smart flash and memory cache keeps its share of it, and the value runs from 34 to 300 as a percentage of the whole.
- It sets capacity aside for the cluster as a whole rather than per virtual machine, and the totals of the form that the engineer sees then divide that capacity among the machines of the cluster.
