   A Unity administrator is planning to enable data reduction on a LUN that is protected by snapshots and replication. What is the impact of data reduction on these data protection features?

   • AData reduction has no effect on snapshots or replication.
   • BData reduction must be disabled on the LUN before enabling snapshots or replication.
   • CData reduction increases the capacity needed for snapshots because they store full copies.
   • DData reduction reduces the capacity needed for snapshots and the bandwidth for replication.

   A Unity array hosts a virtual desktop infrastructure (VDI) environment. Many VMs run the same operating system and applications. The storage team wants to maximize capacity savings. Which data reduction feature should they rely on most?

   • ASnapshots, because they reduce the storage needed for VM backups.
   • BDeduplication, because it eliminates duplicate blocks across the VMs.
   • CThin provisioning, because it reclaims unused space in the VMs.
   • DCompression, because it reduces the size of each VM's data.
