   A VxRail cluster has nodes with 32 GB RAM and 8 cores. The storage team enables deduplication and compression. The memory utilization increases from 50% to 70%. What is the most likely reason?

   • ADeduplication and compression use memory for metadata and hash tables.
   • BThe CPU is overloaded, causing the system to use more memory.
   • CThe storage is full, causing the system to use memory as a cache.
   • DThe network is slow, causing the system to buffer more data in memory.

   A VxRail cluster is being designed for a VDI environment where many virtual desktops run the same operating system and applications. Which configuration consideration is most appropriate?

   • AEnable deduplication only, but disable compression to avoid CPU overhead.
   • BEnable compression only, because deduplication is not effective for VDI.
   • CEnable deduplication and compression to maximize storage efficiency from the high data redundancy.
   • DDisable deduplication and compression because VDI workloads are too performance-sensitive.

   A VxRail cluster runs a real-time analytics platform that processes streaming data. The storage team proposes enabling deduplication and compression to reduce capacity. The nodes are at 70% CPU utilization. What should the architect recommend?

   • AEnable deduplication and compression, and add more nodes to handle the CPU overhead.
   • BDisable deduplication and compression to avoid adding latency to the streaming data pipeline.
   • CEnable deduplication and compression, and accept the performance impact.
   • DEnable only compression, since it has less CPU overhead than deduplication.

   A VxRail cluster has 80 TB of raw capacity. The storage administrator enables deduplication and compression, achieving a 4:1 ratio. The cluster currently stores 200 TB of logical data. What is the actual raw space used?

   • A200 TB
   • B80 TB
   • C800 TB
   • D50 TB

   When planning a VxRail node configuration with deduplication and compression enabled, what should the capacity planner consider about the data reduction ratio?

   • AThe ratio is fixed at 2:1 for all workloads.
   • BThe ratio depends on the workload's data characteristics, such as redundancy and compressibility.
   • CThe ratio is determined by the number of nodes in the cluster.
   • DThe ratio is always 1:1 because deduplication and compression do not affect capacity.
