Q3 Multiple choice

Which two items represent the tradeoffs regarding capacity and performance when deduplication is enabled?

Select all that apply.

  • 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.
