A six-node vSAN ESA cluster contains multiple virtual machines, and a vSAN storage policy with the rule "Failures to tolerate" set to "1 failure - RAID-5 (Erasure Coding)" is assigned. A vSAN administrator has changed the rule in the assigned policy to "2 failures - RAID-6 (Erasure Coding)".
What is the result of this change?
When the rule within the assigned vSAN storage policy is changed, the new policy settings are serially applied to the virtual machines. This ensures that the system avoids excessive network and disk traffic by applying changes incrementally rather than all at once. Therefore, the updated policy is implemented gradually to maintain stability and performance.
The updated policy is serially applied to the virtual machines is the correct answer because changing the rule in the assigned policy will trigger a policy compliance check and a resynchronization of the affected objects. The policy change will not be rejected, queued, or ignored, as it is a valid and supported operation. However, the policy change will not be applied in parallel, as that would cause too much network and disk traffic. Instead, the policy change will be applied one virtual machine at a time, starting with the most critical ones, until all virtual machines are compliant with the new policy.
D - Correcy
A. No changes occur until the policy is reapplied. The policy change is not immediately applied to the virtual machines or objects. Instead, it is queued, and the policy will only be applied when it is reapplied to the virtual machines or objects. This allows you to control when and how the new policy is enforced, giving you flexibility and the opportunity to plan for any potential resource or capacity impacts.
No, if you modified an existing policy, it applied as stated in answer D. The case you detail is if you attach a new storage policy to a VM or an object.
