Questions 26–28

   A vSAN Stretched Cluster has two availability zones, each with three hosts. The witness host is a single ESXi host at a third location. The administrator notices that the witness host has lost connectivity to both zones simultaneously. The vCenter alarms show 'vSAN witness host disconnected' and the vSAN health checks report 'Witness host network partition'. VMs remain running and accessible in both zones. What is the immediate impact on the stretched cluster?

   • AThe cluster will continue to serve I/O, but new writes may be blocked or delayed because the witness cannot participate in quorum for metadata updates.
   • BAll VMs will be powered off because the cluster loses quorum without the witness.
   • CThe witness host will be automatically rebuilt from a snapshot of the data nodes.
   • DThe cluster will automatically fail over all VMs to the preferred site to maintain availability.

   A vSAN Stretched Cluster is experiencing intermittent performance issues. The administrator runs the vSAN health checks and sees a warning on 'Witness host connectivity'. The administrator also checks the Skyline Health diagnostics and finds a 'High latency to witness host' issue. The administrator verifies that the network path to the witness host is within the supported latency limits. What should the administrator do next to further diagnose the issue?

   • ACheck the vSAN performance service metrics for the witness host to see if there are any I/O bottlenecks.
   • BReboot the witness host to clear any temporary issues.
   • CDisable the witness host health check to avoid false alarms.
   • DExamine the vmkernel.log on the data nodes for any vSAN-related errors or warnings.

   What is the correct configuration for fault domains in a vSAN Stretched Cluster?

   • AEach availability zone should be configured as a separate fault domain, and the witness host should be in its own fault domain.
   • BFault domains are not required in a stretched cluster.
   • CThe witness host should be in the same fault domain as the preferred site.
   • DAll hosts should be in a single fault domain to simplify management.
