The Capacity Reserve feature in vSAN 8.0 OSA reduces the amount of capacity reserved for transient and rebuild operations by using a slack space threshold. This threshold is calculated based on the size of the largest component in the cluster and the number of failures to tolerate. If the used space on vSAN datastore exceeds the suggested slack space threshold, the feature will not operate properly and vSAN will revert to using the host rebuild reserve threshold. The other scenarios will not affect the Capacity Reserve feature. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 28

In a vSAN stretched cluster configuration, both data sites are active sites, but one site must be designated as the preferred site and the other site as the secondary or nonpreferred site. This configuration helps to ensure that data remains on a given site in case of a network partition between the sites. If the network connection between the two active sites is lost, vSAN continues operation with the preferred site, unless it is resyncing or has another issue. The site that leads to maximum data availability is the one that remains in operation. The other options are not relevant to this scenario.

The maximum amount of capacity disks an administrator can have in disk groups on a single vSAN OSA host is 35. This is because a single host can have up to five disk groups, and each disk group can have up to seven capacity disks. Therefore, the maximum number of capacity disks per host is 5 x 7 = 35. The other options are not correct, as they are lower than the maximum number of capacity disks per host. References: Designing and Sizing vSAN Storage; [vSAN ReadyNode Hardware Guidance]
