Question

The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing. Which two actions would cause this situation? (Choose two.)

Options

  • ADRS is relocating VMs between vSAN nodes.
  • BHA Virtual Machine Monitoring forced a VM to reboot.
  • CA host failure occurs in the cluster.
  • DA change to the storage policy is applied to the objects.
  • EA VM snapshot is being deleted.

Explanation

The following events trigger resynchronization in the cluster: Editing a virtual machine (VM) storage policy. When you change VM storage policy settings, vSAN might initiate object recreation and subsequent resynchronization of the objects. Certain policy changes might cause vSAN to create another version of an object and synchronize it with the previous version. When the synchronization is complete, the original object is vSAN ensures that VMs continue to run, and resynchronization does not interrupt their operation. This process might require additional temporary capacity. Restarting a host after a failure. Recovering hosts from a permanent or long-term failure. If a host is unavailable for more than 60 minutes (by default), vSAN creates copies of data to recover the full policy compliance. Evacuating data by using the Full data migration mode before you place a host in maintenance Exceeding the capacity threshold of a capacity device. Resynchronization is triggered when a capacity device in the vSAN cluster approaches or exceeds the threshold level of 80 percent.
