To achieve the best performance for the database virtual machines and tolerate two host failures in a vSAN OSA cluster, the administrator must use RAID-1 as the RAID configuration in the storage policy. RAID-1 is a mirroring technique that creates multiple replicas of each object across different hosts. RAID-1 provides the best performance among the available RAID configurations, as it does not involve any parity calculations or stripe splitting. To tolerate two host failures, the administrator must set the Failures to Tolerate (FTT) policy to 2, which means that each object will have three replicas. The other options are not correct. RAID-5 and RAID-6 are erasure coding techniques that split each object into data segments and parity segments across different hosts. RAID-5 can tolerate one host failure, while RAID-6 can tolerate two host failures. However, both RAID-5 and RAID-6 have lower performance than RAID-1, as they involve more complex calculations and network traffic. RAID-0 is a striping technique that splits each object into multiple stripes across different hosts. RAID-0 does not provide any data redundancy or fault tolerance, and therefore cannot tolerate any host failure.

To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.

To avoid storage policy non-compliance, the vSAN maintenance mode option that should be used is Full data migration. This option evacuates all data from the host to other hosts in the cluster and maintains the current object compliance state. This means that the VM objects will have access to all their replicas and will be compliant with their assigned storage policies. The other options might result in storage policy non-compliance, as they do not guarantee full data redundancy or policy adherence. Ensure accessibility only migrates the components that are essential for running the VMs, but might not have access to all their replicas. Partial maintenance mode is not a valid option for vSAN clusters. No data migration does not evacuate any data from the host and might result in VM unavailability or data loss.
