The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host’s controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host’s drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

The maximum amount of capacity disks an administrator can have in disk groups on a single vSAN OSA host is 35. This is because a single host can have up to five disk groups, and each disk group can have up to seven capacity disks. Therefore, the maximum number of capacity disks per host is 5 x 7 = 35. The other options are not correct, as they are lower than the maximum number of capacity disks per host. References: Designing and Sizing vSAN Storage; [vSAN ReadyNode Hardware Guidance]
