A vSAN administrator has recently upgraded a vSAN cluster to 7.0 U1 and has enabled Capacity Reserve features to reduce the amount of capacity reserved for transient and rebuild operations.
Which scenario would prevent this feature from operating properly?
The used space on vSAN datastore exceeding the suggested host rebuild threshold would prevent the Capacity Reserve feature from operating properly. When the used space exceeds this threshold, vSAN may not have enough free capacity to properly reserve space for transient operations and rebuild tasks, which can hinder the effectiveness of the Capacity Reserve feature.
The Answer is C Note that if the used space on the vSAN datastore exceeds the suggested Operations threshold, vSAN might not operate properly. Similarly, if the used space on the vSAN datastore exceeds the suggested Host rebuild threshold https://cormachogan.com/2020/10/29/vsan-capacity-management-in-v7-0u1/
Host build reserve
I feel like this is a trick question because its asking what would prevent Capacity Reserve from operating properly. Wouldn't that mean what did we do before Capacity Reserve which means underutilize space is above 25-30% of the total capcity.
Correct answer should be C

C is the correct
