   A hospital's Dell Unity array has a FAST VP-enabled pool with SAS flash and NL-SAS tiers. The EHR application's LUNs are set to 'Autotier'. The storage administrator is seeing high latency during the day. An analysis shows that the EHR data is on the NL-SAS tier, while a large amount of data from a nightly backup job is on the SAS flash tier. The backup LUNs are also set to 'Autotier'. The backup job runs from 2 AM to 6 AM. What is the most likely cause of the daytime latency, and what is the best corrective action?

   • AThe backup LUNs are set to 'Highest Available'; change them to 'Autotier'
   • BThe backup data is being promoted to flash during the nightly run and is not being demoted quickly enough; change the backup LUNs' policy to 'Lowest Available'
   • CThe EHR data is not being accessed enough to be promoted; manually relocate the EHR LUNs to the flash tier
   • DThe FAST VP relocation cycle is running too frequently; increase the time between cycles

   A storage administrator is planning the deployment of a new Dell Unity array for a large organization. The organization has a mix of workloads with varying performance requirements. The administrator is considering using a single large storage pool with FAST VP enabled, rather than creating multiple smaller pools. What is a key architectural advantage of using a single pool with FAST VP?

   • AIt simplifies management by allowing all LUNs to share the same tiering policy
   • BIt guarantees that all workloads will have the same performance level
   • CIt eliminates the need for data protection features like snapshots and replication
   • DIt provides a larger set of drives for the FAST VP algorithm to optimize across, improving the efficiency of data placement

   A company is planning to deploy a new Dell Unity array. The storage administrator is explaining the benefits of FAST VP to the management team. The management team asks how FAST VP can improve performance without requiring them to manually move data. Which statement best describes the underlying mechanism of FAST VP?

   • AIt compresses data on the slower tiers to increase available capacity
   • BIt creates multiple copies of hot data on different tiers to ensure redundancy
   • CIt uses a caching algorithm to store frequently accessed data in a portion of the array's RAM
   • DIt automatically relocates data between different drive tiers within a storage pool based on access frequency

   Which benefit does FAST VP provide in a Dell Unity environment?

   • AEliminates the need for backup software
   • BReduces the need for manual data migration between drive types
   • CIncreases the total raw capacity of the storage system
   • DGuarantees zero data loss in the event of a drive failure
