Which three configurations for read caching in Cisco HyperFlex are valid? (Choose three.)

A: Battery-Initiated Read-back (default): Only read data and most commonly used data are deposited in the Level 4 read-back cache B: Write-back (default): Only write information and most commonly used information are deposited in the cache C: Write-through (install option for VDI): Only most commonly used data is cached: optimizing VDI performance D: No caching (SSD): With all-flash nodes; because there is little difference in read speeds between SSDs E: Level 4 cached (SSD): With semi-flash nodes; there is a large difference in read speeds between SSDs F: Write-first (default for VDI): Infrequently used data is cached: freeing system resources for VDI performance
