   A stretched cluster has a witness host in a third site. The administrator is troubleshooting a 'vSAN Witness Health' alarm that shows 'Witness not reachable'. The data hosts in both sites are healthy and can communicate with each other. The administrator checks the witness host and finds that it is powered on and the vSAN VMkernel adapter is configured correctly. What should the administrator check next?

   • ACheck the firewall rules on the witness host to ensure vSAN traffic is allowed.
   • BVerify that the witness host has a valid vSAN license.
   • CVerify that the witness host is on the same subnet as the data hosts.
   • DCheck the vSAN health service on the witness host to ensure it is running.

   A vSAN cluster is using a standard vSwitch with two uplinks for vSAN traffic. The administrator notices that the vSAN network is experiencing intermittent packet loss. The vSAN health check 'vSAN Network' shows 'Partitioned' for some hosts. The administrator checks the physical switches and finds that one of the uplinks is flapping. What should the administrator do to resolve the issue?

   • AConfigure the vSAN VMkernel adapter to use 'Route based on physical NIC load' to avoid the flapping uplink.
   • BRemove the flapping uplink from the vSAN VMkernel adapter and use only one uplink for vSAN traffic.
   • CIncrease the MTU on the vSAN VMkernel adapter to reduce packet loss.
   • DCheck the physical switch configuration for issues such as duplex mismatch or cable problems that may cause the uplink to flap.

   • BOne or more hardware components are not listed on the vSAN Compatibility Guide
   • CThe vSAN network is not configured with jumbo frames
   • DThe vSAN cluster has insufficient memory for the configured storage policies

   A vSAN cluster is reporting a 'vSAN object health' alarm for a mission-critical VM. The VM is running but the administrator notices that the 'vSAN performance service' shows high latency for the affected VM's disk. The health check 'vSAN object health' shows 'Object accessible' but 'Component health' shows one component 'Degraded'. The cluster is configured with FTT=1 and RAID-1 (mirroring). What should the administrator do first to resolve the degraded component?

   • ARemove the disk group that contains the degraded component and re-add the disks.
   • BImmediately re-apply the VM storage policy to force a rebuild of the degraded component.
   • CCheck the 'vSAN Disk Health' checks to identify if the underlying disk has a predictive failure or is experiencing errors, then evacuate the disk if needed.
   • DUse the 'vSAN Health Service' to run the 'vSAN Object Health' check and then 'Rebuild' the object from the vSAN Health panel.

   An administrator notices a vSAN health check that reports a warning about the cluster's network configuration. What is the primary purpose of vSAN health checks?

   • ATo guarantee that all vSAN objects are always accessible and fully redundant
   • BTo provide a proactive assessment of the vSAN cluster's configuration and operational state
   • CTo replace the need for regular monitoring and alerting in the vSAN environment
   • DTo automatically remediate any detected configuration issues without administrator intervention
