To protect a virtual machine against a disk or disk group failure, the storage policy must have a failure tolerance method (FTM) of RAID-1 or RAID-6 and a failure to tolerate (FTT) value of at least 1. RAID-1 mirrors the data across multiple disk groups, while RAID-6 uses erasure coding to stripe the data and parity information across multiple disk groups. RAID-5 is not suitable for this scenario, as it can only tolerate one disk failure per stripe. FTT 2 or 3 would require more disk groups than available in the cluster. Therefore, the correct options are C and E. References: 1, page 8; 2, section 3.1

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.

In a vSAN stretched cluster configuration, both data sites are active sites, but one site must be designated as the preferred site and the other site as the secondary or nonpreferred site. This configuration helps to ensure that data remains on a given site in case of a network partition between the sites. If the network connection between the two active sites is lost, vSAN continues operation with the preferred site, unless it is resyncing or has another issue. The site that leads to maximum data availability is the one that remains in operation. The other options are not relevant to this scenario.
