You are configuring a vSAN Stretched Cluster in a VVF environment. The secondary site loses network connectivity to the primary site, but the witness appliance is still reachable by both sites.
What happens to the virtual machines?
A. VMs on the secondary site are restarted on the primary site.
B. VMs on both sites are powered off to prevent split-brain.
C. VMs continue to run on their respective sites, but vSAN resyncs data to the witness.
D. The primary site forms a quorum with the witness, and VMs on the secondary site lose access to storage and are restarted on the primary site.
Explanation:
In a vSAN Stretched Cluster, if the inter-site link fails but the witness is accessible, the site that can communicate with the witness (typically the preferred/primary site) forms a quorum. The secondary site loses quorum, causing its VMs to lose storage access. vSphere HA will restart those VMs on the primary site.
