Question

Options

• AFTT=2 (RAID-1 Mirroring)
• BFTT=2 (RAID-6 Erasure Coding)
• CFTT=1 (RAID-1 Mirroring)
• DFTT=1 (RAID-5 Erasure Coding)
• EFTT=3 (RAID-1 Mirroring)

• A
  4% (1)
• B
  4% (1)
• C
  79% (19)
• E
  13% (3)

Explanation

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 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 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. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID- 2E99D1D1-1D9E-4C9A-9F17-0E1A7C846F5D.html
