Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?
When proper VM Storage Policy Affinity Rules are set on a stretched vSAN cluster, it ensures that VMs on one site access their VMDKs locally on the same site. This means that if a site becomes disconnected, the VMs on the other site will continue to have access to their VMDKs without disruption. This setup is designed to maintain availability and performance despite a site failure.
I think B. If vms running on site A (compute) are using storage on site A, and VMs on site B are using storage on site B, using affinity rules, if we lost a site, the other site continue working without any problem.
B for sure,,,, Setting proper VM/Host Group Rules and VM Storage Policy Affinity Rules are beneficial for several reasons Bandwidth is not unnecessarily sent across the inter-site link Lower inter-site bandwidth utilization In the situation where the alternate site is disconnected, the VM will continue to have access to its vmdk. from https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7341-sub5
B, but only if the affinity was configured with should option
This is a giveaway. The fact that they said "proper" means you're likely going to choose the answer that sounds like best-case scenario. Answer B - VMware has writeups so you can read from the local site.
B is the correct : soft affinity rules are used to keep the VM local to the same site/fault domain where possible.
