Two actions that would cause some objects to be currently resyncing are:

• A change to the storage policy is applied to the objects. This action triggers a resynchronization of objects to make them compliant with the new policy settings, such as FTT, RAID level, stripe width, etc. The resynchronization process copies data from one host to another to create or update replicas or parity segments.
• A host failure occurs in the cluster. This action causes some objects to become non-compliant with their storage policy, as they lose one or more replicas or parity segments due to the host failure. The resynchronization process rebuilds the missing components on other hosts in the cluster to restore compliance and availability.References: : VMware vSphere Storage Guide, page 129 : Monitor the Resynchronization Tasks in the vSAN Cluster 1 : VMware vSAN Specialist v2 Exam Preparation Guide, page 13

To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host’s controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host’s drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

Horizon and Dynamic Environment Manager are two end-user computing (EUC) solutions that can be implemented on vSAN storage to provide a virtual desktop infrastructure (VDI) solution and store applications running inside the VDI environment. Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, while Dynamic Environment Manager is a tool that provides personalization and dynamic policy configuration across any virtual, physical, and cloud-based Windows desktop environment. The other solutions are not directly related to VDI or application storage on vSAN.
