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.

To upgrade multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters, the administrator can upgrade two witness node types: appliance witness node and nested witness node. An appliance witness node is a virtual ESXi host that runs on a physical ESXi host and contains the witness components of VM objects stored in the vSAN cluster. A nested witness node is a virtual ESXi host that runs on another virtual ESXi host and contains the witness components of VM objects stored in the vSAN cluster. Both types of witness nodes can be managed by vLCM as independent nodes since vSphere 7.0 Update 3, as long as they are version 7.0 Update 2 or later. The other options are not correct. A shared witness node is a witness node that serves multiple vSAN clusters, which is not supported by vLCM. A dedicated witness node is a witness node that serves only one vSAN cluster, which is not a specific type of witness node. A physical witness node is aphysical ESXi host that contains the witness components of VM objects stored in the vSAN cluster, which cannot be upgraded by vLCM.

The minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring) is six hosts. This is because a vSAN stretched cluster requires at least three hosts per site, and each site must have enough hosts to tolerate one host failure. Therefore, the minimum configuration is three hosts per site, plus one witness host at a third site, for a total of six hosts. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 14
