A vSAN cluster recently experienced a network partition due to a major network outage. The system administrator noticed that:
• The virtual machines running on the vSAN cluster remained powered on all hosts.
• When the network was restored, some VMs were duplicated between the different ESXi hosts.
What should the administrator check to prevent this from happening again?
The issue described involves virtual machines being duplicated between ESXi hosts after a network partition and restoration. This suggests that while the VMs stayed powered on during the partition, there may have been confusion about their active state due to the network partition. To prevent this, it's important to check and configure vSphere HA Advanced Parameters, which include settings that control how HA responds to network partitions and other failures, ensuring proper reconfiguration and avoiding duplication of VMs.
My answer is D.
