   A financial services firm runs a VxRail cluster hosting a high-frequency trading application that requires sub-millisecond latency. The storage team proposes enabling deduplication and compression to reduce capacity costs. The cluster nodes are CPU-constrained, with 80% average utilization. What should the architect recommend?

   • AEnable deduplication and compression, and accept the minor performance impact.
   • BKeep deduplication and compression disabled to avoid adding latency and CPU contention.
   • CEnable deduplication and compression, and add more memory to the nodes.
   • DEnable only compression, since it has no CPU overhead.

   A VxRail cluster has 200 TB of raw capacity. The storage administrator enables deduplication and compression, achieving a 5:1 ratio. How much logical data can be stored before the cluster is full?

   • A1,000 TB
   • B40 TB
   • C200 TB
   • D500 TB

   A VxRail cluster has 100 TB of raw storage capacity. If deduplication and compression provide a 2:1 data reduction ratio, what is the effective usable storage capacity for user data?

   • A200 TB
   • B150 TB
   • C50 TB
   • D100 TB

   Which statement correctly describes how deduplication and compression achieve storage savings in a VxRail cluster?

   • ADeduplication compresses data blocks, and compression removes duplicate blocks.
   • BDeduplication reduces the number of VMs, and compression reduces the number of disks.
   • CDeduplication and compression both work by reducing the number of nodes in the cluster.
   • DDeduplication removes redundant data blocks across the cluster, and compression encodes data using fewer bits.

   A media company is deploying VxRail for video editing. The storage team wants to enable deduplication and compression to reduce capacity. The video files are large, mostly unique, and already compressed. What should the architect recommend?

   • AEnable only deduplication, since it works well on compressed files.
   • BDisable deduplication and compression because the data is already compressed and mostly unique.
   • CEnable only compression, since video files compress well.
   • DEnable deduplication and compression to maximize capacity savings.
