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]

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

The purpose of the TRIM/UNMAP process is to reclaim disk space that is no longer used by the guest operating system or the virtual machine. TRIM and UNMAP are commands that allow the guest operating system to inform the underlying storage layer that certain blocks are no longer in use and can be freed up. This process helps to improve storage efficiency and utilization,especially for thin-provisioned disks that grow dynamically as data is written to them. The other options are not correct. The TRIM/UNMAP process does not collect vSAN log files, repair internal cache errors, or delete orphaned snapshots. These are different tasks that are performed by other tools or processes.
