問題文
Preemptible services on the resource allocation platform are being stopped and restarted often enough that users complain. An administrator considers guaranteeing a minimum run time per node pool. What is the trade-off?
選択肢
- The guarantee also raises the work's priority, which resolves the complaint without affecting anything else.
- The setting applies only to work that was already marked as non-interruptible, so it changes nothing for the services in question and the restarts must be addressed by raising the share.
- Once started, such work behaves as if it cannot be interrupted for that duration; on a pool that also serves interactive or latency-sensitive work, those requests may then be delayed significantly.
- The guarantee is enforced by reserving the resources in advance, so the pool's utilization drops by the same proportion.
