Which statement is true regarding virtual disk availability in this environment?
In a vSphere 7.0 environment with a vSAN default storage policy, each virtual disk is configured to have two replicas of data. This default policy, also known as RAID-1 (Mirroring), ensures data redundancy by creating two copies of the data on separate vSAN disk groups within the clusters. This configuration allows the virtual disk to tolerate the failure of a disk group or a host, thus providing data protection and high availability.
The vSAN default storage policy in vSphere 7.0 ensures that each virtual disk is configured with two replicas of data. This means that for every virtual disk, there will be two copies of the data stored on separate vSAN disk groups within the clusters. This provides redundancy and data protection by allowing the virtual disk to withstand the failure of a disk group or a host. Option A is incorrect because replicas will be placed on different disk groups, but they can potentially be placed on the same host. Option B is incorrect because while the replicas are placed on different disk groups, they can still be placed on the same host. Option C is incorrect because the vSAN default storage policy configures two replicas of data, not four replicas.
Default VSAN storage policy is FFT=1, which means we can lose one copy of the data. In order to comply with this, we need at least one more copy of the data. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-C228168F-6807-4C2A-9D74-E584CAF49A2A.html

Can somebody link a good reference document? The one listed isn't coming up.
RAID1 is the default policy
How many disks does a server node need as a minimum to participate in a vSAN cluster? It is generally recommended to have two disk groups per vSAN node, as a minimum.
