Question
A vSAN Administrator has a cluster of six vSAN nodes. The vSAN datastore was 55% utilized, and due to a power outage, one node was lost. The vSAN administrator needs to resolve the storage policy compliance for the virtual machines on RAID-5. Which action, if any, needs to be taken to meet this goal?
Options
- ANo action is needed since vSAN automatically rebuilds the objects
- BThe one failed node must be restored
- CChange the RAID-5 FTT from 2 to 1
- DTrigger vSAN object repair from ESXCLI

Explanation
In a RAID-5 (Erasure Coding) configuration, data and parity are distributed across at least four nodes. When one node fails in a six-node vSAN cluster, the objects on RAID-5 become non- compliant because the minimum number of nodes required to maintain data and parity integrity is no longer available. vSAN cannot rebuild or repair these objects until the failed node is restored or replaced, after which compliance will be automatically reestablished.
