An all-flash vSAN cluster contains four nodes.
Which two storage policies can the cluster satisfy? (Choose two.)
An all-flash vSAN cluster contains a sufficient number of capacity devices and cache devices to support different RAID levels.
FTT=3(RAID-1 Mirroring) - This policy requires at least 4 capacity devices, where each object is mirrored across three copies of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.
FTT=1 (RAID-1 Mirroring) - This policy requires at least 2 capacity devices, where each object is mirrored across one copy of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.
FTT=2 (RAID-6 Erasure Coding) - This policy requires at least 6 capacity devices, where each object is striped across two sets of parity and data. This cannot be satisfied by the 4 nodes all-flash vSAN cluster.
FTT=1 (RAID-5 Erasure Coding) - vSAN does not support RAID-5 Erasure coding.
