During a design workshop for a stretched vSAN cluster, the requirement that some of the VMs be configured with no-mirror between sites was discussed.
Which three recommendations should the architect provide to address an event of a network partition between two sites? (Choose three.)
For a VSAN stretched cluster, to handle a network partition between two sites, it is crucial to have isolation addresses configured correctly to detect and manage network isolation events. One isolation address should reside in the site 1 data center and another in the site 2 data center. This setup allows vSphere HA to validate complete network isolation during connections failures. Additionally, using DRS rules to ensure that VMs run where the data resides helps to keep workloads optimally placed in terms of data locality and availability. Therefore, the recommendations include configuring isolation addresses in both site 1 and site 2 data centers and using VMware vSphere DRS rules to force the VMs to run where the data resides.
CDF is correct for sure...here Network Isolation Response and Multiple Isolation Response Addresses In a Virtual SAN Stretched Cluster, one of the isolation addresses should reside in the site 1 datacenter and the other should reside in the site 2 datacenter. This would enable vSphere HA to validate complete network isolation in the case of a connection failure between sites. https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/VMware-Virtual-SAN-6.1-Stretched-Cluster-Guide.pdf/subassets/page38.pdf
I think CDF
This confirms C and F: In a VSAN stretched cluster, one of the isolation addresses should reside in the site 1 data center and the other should reside in the site 2 data center. This would enable vSphere HA to validate complete network isolation in the case of a connection failure between sites. https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/VMware-Virtual-SAN-6.1-Stretched-Cluster-Guide.pdf/subassets/page38.pdf
