質問 # 279
Which snapshot option is set automatically when a Pool is configured?
- A. Total Pool Consumption
- B. Pool Automatic Deletion Policy
- C. Snapshot Pool Consumption
正解：B
解説：
Explanation
The snapshot option that is set automatically when a pool is configured is the Pool Automatic Deletion Policy.
This option determines how the system handles the deletion of snapshots when the pool reaches a certain threshold of capacity utilization. The user can choose between three policies: Never Delete, Delete Oldest, or Delete LowestPriority. The Total Pool Consumption and the Snapshot Pool Consumption are not snapshot options, but rather metrics that show the amount of pool space consumed by the pool data and the snapshots respectively.
