2V0-620 · Question #9
Which two Virtual SAN related actions might start resynchronization of virtual machine objects? (Choose two.)
The correct answer is A. Editing a virtual machine storage policy to increase the number of replicas. C. Editing a virtual machine storage policy to increase the number of disk stripes. When a vSAN storage policy is modified to demand more resources - specifically more replicas or more stripes - vSAN must provision new data components, which triggers resynchronization to satisfy the updated policy.

Why each option
When a vSAN storage policy is modified to demand more resources - specifically more replicas or more stripes - vSAN must provision new data components, which triggers resynchronization to satisfy the updated policy.
Increasing the number of replicas forces vSAN to provision additional replica components on different hosts, triggering a resynchronization operation to copy existing VM object data to the new replica locations and bring the object into compliance with the updated policy.
Reducing the number of replicas causes vSAN to retire and delete excess replica components rather than create new ones, so no resynchronization is initiated.
Increasing the number of disk stripes requires vSAN to create additional stripe components for the VM object, triggering resynchronization to redistribute the object's data across the newly required stripe configuration.
Reducing the number of disk stripes causes vSAN to consolidate existing stripe components rather than provision new ones, so resynchronization is not triggered.
Concept tested: vSAN storage policy changes triggering object resynchronization
