You created a LUN in a new volume on your NetApp ONTAP cluster. You enabled the default Snapshot schedule and enabled Snapshot autodelete on the volume.
In this scenario, in which three situations does the Snapshot autodelete feature automatically delete Snapshot copies in the volume? (Choose three.)
Snapshot autodelete in a NetApp ONTAP volume is triggered in specific scenarios to manage storage efficiently. The three scenarios where Snapshot autodelete is employed are: when the Snapshot reserve space is nearly full, when the volume is nearly full, and when the overwrite reserve space is full. These triggers help ensure that there is enough space in the volume to maintain performance and prevent storage issues. The aggregate being nearly full or the LUN being nearly full does not directly impact the Snapshot autodelete feature.
It is B, D and E
A, D and E.....Depending on what is selected in the "Trigger" option, Snapshot Autodelete will automatically delete a snapshot when, either the volume space utilized, or the snapshot reserve reaches a threshold capacity specified below. Automatic deletion of Snapshot copies from flexible volumes Data ONTAP can automatically delete one or more Snapshot copies on the volume, provided the Data ONTAP Snapshot copy autodeletion policy is enabled and set to trigger when the overwrite reserve is nearly full on the volume.
