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]

To view the resynchronizing metrics, the vSAN administrator should open the Backend performance category. This category shows the performance of vSAN data components, such as read/write latency, IOPS, throughput, congestion, and resync traffic. The other categories are not relevant for this task. Disks shows the performance of physical disks in the cluster, Host Network shows the network performance of vSAN hosts, and Resvnc Latency shows the latency of resynchronization operations.

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
