   What is a common misconfiguration that can cause witness host issues in a vSAN Stretched Cluster?

   • ASetting the witness host's memory to the minimum required
   • BUsing a witness host that is not part of the vCenter Server domain
   • CPlacing the witness host in the same fault domain as one of the availability zones
   • DConfiguring the witness host with a single network adapter

   Which symptom indicates a network partition between the two availability zones in a vSAN Stretched Cluster?

   A vSAN Stretched Cluster has Zone A (preferred) and Zone B (secondary). A complete site failure occurs at Zone B, and all hosts in that zone become unavailable. The witness host remains reachable from Zone A. What is the expected outcome for VMs that had replicas on both zones?

   • AVMs will be automatically failed over to the witness host.
   • BVMs will be restarted on Zone A only if they were configured with a failover priority.
   • CVMs will continue to run on Zone A, and the cluster will enter a 'degraded' state until Zone B is restored.
   • DAll VMs will be powered off because the cluster loses quorum without Zone B.

   A vSAN Stretched Cluster has Zone A as the preferred site and Zone B as the secondary site. A network partition occurs between the two zones, but the witness host remains reachable from both zones. The administrator observes that VMs in Zone B are still running, but vCenter reports that the cluster is in a 'partitioned' state. What is the expected behavior of the cluster in this scenario?

   • ABoth zones will continue to serve VMs independently because the witness is still reachable.
   • BThe witness will vote with Zone A, allowing Zone A to continue serving VMs, while Zone B becomes non-compliant and its VMs may be restarted when connectivity is restored.
   • CVMs in Zone B will be powered off because the preferred site is unavailable.
   • DVMs in Zone A will continue to run, and VMs in Zone B will be restarted on Zone A.

   A VCF administrator manages a vSAN Stretched Cluster with two availability zones connected over a 10 Gbps link. Users report that VMs in Zone A are experiencing intermittent I/O latency, while VMs in Zone B are unaffected. The vSAN health checks show a 'Network latency check' warning between Zone A and the witness host, but the link between the zones appears healthy. The administrator verifies that the witness host is located at a third site. What is the most likely cause of the latency issue?

   • AThe network path from Zone A to the witness host has higher latency than the inter-site link, causing stretched cluster operations to time out.
   • BThe witness host is running an older ESXi version than the data nodes, causing a protocol mismatch.
   • CThe vSAN cluster is configured with a single fault domain that spans both zones, preventing proper data placement.
   • DThe witness host is placed in a fault domain that is incorrectly associated with Zone A.
