VMware Live Site Recovery uses VM readiness signals to control recovery sequencing between priority groups. Recovery Priority is used to start and validate higher-priority workloads before lower-priority workloads continue, which is important for application dependency chains such as identity services, databases, middleware, and application servers. A VM being registered or powered on does not prove that the guest operating system is usable. Similarly, final replication completion only confirms storage synchronization, not guest readiness. VMware Tools heartbeat provides a guest-level indication that the operating system has started and is responsive. This makes it the correct mechanism for determining that a recovery priority step has completed and that the recovery plan can continue to the next priority group. The “successfully recovered” state is the result of the recovery workflow, not the signal used to progress between priority groups.

NFS must be used as principal storage because the hosts have no local storage available. vSAN OSA and vSAN ESA both require local storage devices on the ESX hosts to create the vSAN datastore, so neither can be selected as principal storage in this design. NVMe over RDMA is supported as a high-performance NVMe over Fabrics transport in vSphere, but in the VCF storage model it is treated as supplemental storage rather than principal storage for workload domain creation. Therefore, NVMe over RDMA cannot be the initial principal datastore used to build the Workload Domain. NFS is the valid principal storage option from the provided choices, and after the Workload Domain is created, NVMe over RDMA can be added as supplemental storage for additional performance or capacity use cases. This build order satisfies the lack of local disks, uses a supported principal storage type, and allows the NVMe over RDMA design requirement to be met after the domain exists.

The correct steps are to create an NFS export on the storage array and mount the NFS datastore on each ESX host in the cluster. NFS datastore creation begins on the storage system, where the storage administrator creates and exports the NFS volume or directory with the required access permissions for the ESX hosts. After the export exists, vSphere mounts that export as a datastore. For a clustered VCF workload domain, the datastore must be mounted consistently across all ESX hosts in the cluster so that HA, DRS, vMotion, and VM placement can operate correctly. Mounting the datastore on only one host would create inconsistent datastore accessibility and could prevent workloads from moving or restarting on other hosts. “Attach NFS as a secondary datastore” is not the correct procedural step; the datastore is created and mounted as a vSphere datastore. Configuring vSAN is irrelevant because the workload domain already uses NFS storage and the task is to add another NFS datastore.
