Question

Which three configurations are required to enable read caching in Cisco HyperFlex? (Choose three.)

Accepted Answer

A. Write-back (default): Only write information and the most commonly used information are deposited in the cache.; C. No caching (SSD): With all-flash nodes, because there is little difference in read speeds between SSDs.; E. Write-through (install option for VDI): Only the most commonly used data is cached, optimizing VDI performance.

Answer

Level 4 cached (SSD): With semi-flash nodes, there is a large difference in read speeds between SSDs.

Answer

Battery-Initiated Read-back (default): Only read data and most commonly used data are deposited in the Level 4 read-back cache.

Answer

Write-first (default for VDI): Infrequently used data is cached, freeing system resources for VDI performance.
