An all-flash vSAN ESA cluster has four nodes.

Which two storage policies can this cluster satisfy?

Choose two
  • A FTT=3 (RAID-1 Mirroring)
  • B FTT=2 (RAID-1 Mirroring)
  • C FTT=l (RAID-5 Erasure Coding)
  • D FTT=l (RAID-1 Mirroring)
  • E FTT=2 (RAID-6 Erasure Coding)
Explanation

vSAN ESA supports FTT=1 RAID-1 mirroring with a minimum of three hosts and FTT=1 RAID-5 erasure coding with a minimum of three hosts. A four-node cluster therefore satisfies both policies. Higher fault-tolerance policies require more hosts: FTT=2 RAID-1 requires five, FTT=2 RAID-6 requires six, and FTT=3 RAID-1 requires seven.
