61 A. It must have a read-only Vserver root volume. B. It must be in the same cluster as the source Vserver C. It must be created with the same language type as the source Vserver. D. It must have a different storage efficiency policy than the source Vserver. Correct Answer: C : Training material: Clustered_Data_ONTAP_82_Data_Protection_Guide How volume SnapMirror works with deduplication You can use volume SnapMirror to replicate a deduplicated volume regardless of size of the volume and logical data in the volume. When using volume SnapMirror with deduplication, you must consider the following information: You can enable deduplication on the source system, the destination system, or both systems. The shared blocks are transferred only once. Therefore, deduplication also reduces the use of network bandwidth. When the volume SnapMirror relationship is broken, the default deduplication schedule is applied at the destination storage system. When configuring volume SnapMirror and deduplication, you should coordinate the deduplication scheduleand the volume SnapMirror schedule. You should start volume SnapMirror transfers of a deduplicated volume after the deduplication operation is complete. This schedule prevents the sending of undeduplicated data and additional temporary metadata files over the network. If the temporary metadata files in the source volume are locked in Snapshot copies, these files consume extra space in the source and destination volumes. QUESTION 112 What happens if a load Sharing (LS) mirror replies a Vserver root volume to any node in the cluster and you promote one of the mirror destinations? A. All clients temporarily gain read/write access to the root volume B. The original source volume is prevented from becoming stale. C. All clients must re mount.
