QUESTION: 69 What happens when the Thin Provisioning property is set for a LUN?
A. This property allows the volume size to exceed the amount of available space. B. A share reserves exactly enough space to completely fill the share. C. Thin provisioning allows the storage administrator to divide the pool capacity into evenly sized LUNs. D. A ZFS file system is created by setting a quota and reservation to the same value.
Answer: A

QUESTION: 73 Which two items represent the tradeoffs regarding capacity and performance when deduplication is enabled?
A. Netbackup backups will use much less space if stored on a deduplicated share, and performance is not impacted because the workload is sequential. B. Netbackup backups will see little benefit in space utilization, but also little impact on performance due to the sequential writes. C. The effective capacity of disk space may be greatly enhanced with deduplication, and the performance impact will be greatly dependent on the amount of data to be written, the blocksize selected, and whether the DDT stays in ARC (memory) or not. D. Video streams, encrypted data, and precompressed data may see little or no capacity benefit with deduplication, and throughput performance will be degraded, perhaps even significantly.
Answer: A, D
QUESTION: 74 Which statement is false about Cluster Configuration of ZFS Storage Appliances?
A. To utilize resource of both nodes simultaneously, you need at least two storage pools: one that maps to node1 and another that maps to node2. B. You can always set up an Active-Active Cluster Configuration anytime if you use Striped Data profiles. C. In Cluster environment, only one node at a time can be the owner of each storage pool. D. If a controller fails, the other controller will take control of all known resources and provide the services associated with those resources.
Answer: C
