問題文
Two server pools are configured on a five-node cluster. A node that belongs to the more important pool fails and that pool falls below its minimum size. What does the clusterware do?
選択肢
- It starts an additional instance on one of the surviving servers of the deficient pool, because the minimum size counts instances rather than servers.
- It moves a server from another pool of the cluster of the site into the deficient pool, taking it from a less important pool even if that pool then falls below its own minimum size.
- It leaves the pools as they are, because the minimum size is a single hint that is evaluated when the cluster of the site starts.
- It moves a server from another pool into the deficient pool, taking it solely from a pool that stays above its own minimum size, and if no such pool exists the deficient pool stays below it.
