The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

To implement HCI mesh between two clusters on vSAN that are located in geographically separate sites, the vSAN administrator should consider the following requirements:

• Either Layer 2 or Layer 3 communications can be used. HCI mesh supports both Layer 2 and Layer 3 network configurations, as long as the network latency and bandwidth requirements are met3
• The configuration must meet the same latency and bandwidth requirement as local vSAN. HCI mesh requires a network latency of less than or equal to 5 ms RTT between any two hosts in the participating clusters, and a network bandwidth of at least 10 Gbps for the vSAN network vmkernel port3 References: 3: VMware vSAN Specialist v2 Exam Preparation Guide, page 15

The reason why the vSAN administrator cannot find any vSAN performance statistics on the cluster summary page is that the vSAN performance service is not enabled. The vSAN performance service is a feature that collects and analyzes performance metrics and displays them in graphical charts in vCenter. The vSAN performance service must be turned on manually for each vSAN cluster, as it is not enabled by default. The other options are not correct. The integration of vRealize Operations Manager with the vSAN cluster is not required to view vSAN performance statistics, as they are available in vCenter. The administrator’s permissions on the cluster level do not affect the visibility of vSAN performance statistics, as they are accessible to any user who can view the cluster. vSAN performance statistics are not only available via CLI, as they can also be viewed in vCenter using the vSAN performance service.
