VMware 3V0-23.25 Exam Dumps - Actual Questions Answers

vSAN ESA Storage Clusters are the optimal choice because the workload profile is capacity-heavy and benefits from disaggregated storage. The requirement for 2.5 PB of application data, archival workloads, gateways, and development/test applications indicates a need to scale storage capacity independently from compute resources. VMware Cloud Foundation describes a vSAN storage cluster as a disaggregated storage solution based on vSAN ESA. It provides storage resources but not compute resources, and its datastore can be mounted by vSAN compute clusters or vSAN HCI clusters. This model is designed for storage-dense environments where capacity and performance can be expanded without adding unnecessary compute. A standard vSAN ESA HCI cluster is excellent for high-performance workloads, but it scales compute and storage together. vSAN OSA all-flash and hybrid use the older disk-group architecture and are less suitable for this large-capacity, storage-centric design. Therefore, the principal storage recommendation should be vSAN ESA Storage Clusters to meet scalability, performance, and capacity growth requirements.

The prerequisite is to enable vSAN on the non-vSAN cluster so it can operate as a vSAN compute cluster. A vSAN compute cluster is a vSphere cluster that does not contribute local vSAN capacity, but it has vSAN functionality enabled so it can mount a remote vSAN datastore provided by a vSAN Storage Cluster. The Datastore Management option under the vSAN section appears only when the consuming cluster is prepared for vSAN datastore sharing. Without vSAN enabled in compute-cluster mode, the vSphere cluster remains a conventional VMFS-backed cluster and cannot use the vSAN remote datastore management workflow. The cluster does not need to be in a different VCF Workload Domain, and there is no requirement that the storage cluster maintain exactly 80% free space before the option appears. A fourth host is also not required simply to mount remote vSAN capacity. The key requirement is enabling vSAN capability on the client cluster so it can communicate with and consume the remote ESA datastore.

The requirement is to alternate the primary site every six months, which requires a disaster recovery design that can reverse protection direction after failover. Inventory mappings define how resources such as compute resources, folders, networks, and datastores map between the protected and recovery sites. Using “Prepare reverse mappings” during inventory mapping creation ensures that the same mapping structure can be used when the recovery site later becomes the protected site. After a failover or planned migration succeeds, VMware Live Site Recovery uses the re-protect operation to reverse the protection relationship. This makes the formerly recovered site the new protected source and prepares replication and recovery plans for failback or for the next scheduled site rotation. A test recovery plan validates recovery without changing the primary site. Extending the network can simplify workload mobility but is not required for reprotection. Reconfiguring vSAN Data Protection manually is not the Live Site Recovery workflow for reversing protected and recovery site roles.
