VMware 3V0-23.25 Exam Dumps

The workload domain should use Fibre Channel as principal storage because the existing five hosts already have resilient HBAs and are connected to a dedicated, highly resilient storage area network. The third-party block storage is also stated to have sufficient scale, capacity, and IOPS for the new workload requirements only, so it should be reused where it directly fits: the VI workload domain. VMware Cloud Foundation supports Fibre Channel as both principal and supplemental storage for VI workload domains. The management domain should use VMware vSAN as principal storage because the four new servers are being purchased for the management domain, and the existing block storage is not sized for management workloads. vSAN is a native VCF principal storage model for management domains and provides automated deployment, policy-based management, lifecycle integration, and integrated operations. iSCSI is not the right answer because the scenario describes Fibre Channel SAN connectivity and HBAs, not an iSCSI design. vSAN for the workload domain would also fail the reuse requirement because it would ignore the existing block storage investment. Reference topics: Principal Storage, Fibre Channel Storage Model, vSAN Storage Model, Management Domain Storage.

When vertically scaling a vSAN ESA cluster, adding the same model and capacity drives helps preserve a balanced and predictable cluster design. vSAN works best when hosts use uniform storage configurations. The guidance states that unbalanced host configurations reduce predictability of storage performance because vSAN does not store the same number of components on each host, can introduce different maintenance procedures, and can reduce performance on hosts with smaller or different device types. In ESA, each storage device contributes both capacity and performance through the storage pool model, so mixing device models, endurance classes, or capacities can create uneven consumption and inconsistent backend behavior. Using the same drive model and capacity across hosts improves capacity symmetry, keeps maintenance and replacement procedures consistent, and makes performance planning more predictable. The cache-drive option is incorrect because ESA is single-tier and does not use separate cache and capacity tiers. Equal cache and capacity tiers apply to OSA-style thinking, not ESA. vSAN File Services being configured does not drive the requirement to use identical drives.

The available custom recovery steps are top-level commands, message prompts, and per-machine commands. VMware Live Site Recovery recovery plans operate like automated runbooks, and administrators can insert custom steps to match business continuity requirements. Broadcom TechDocs states that custom recovery steps can run commands or present messages to the user during a recovery. Command recovery steps are divided into two categories: top-level commands and per-virtual-machine commands. Top-level commands are inserted directly into the recovery plan and run on the VMware Live Site Recovery server. Per-machine commands are associated with individual recovered VMs and run before or after that VM is powered on, depending on placement in the workflow. Message prompts are interactive steps that pause the plan until an operator acknowledges the message, making them useful for manual validation, external approvals, or runbook checkpoints. IP reconfiguration is handled through recovery plan networking and guest customization, not as a custom step type. Writable storage snapshots are part of test recovery/storage behavior, not a custom recovery step. Reference topics: VMware Live Site Recovery Recovery Plans, Creating Custom Recovery Steps, Top-Level Commands, Message Prompts, Per-VM Commands.

The Live! vSphere Heavy Hitter VM dashboard is the correct place to identify which virtual machines are driving storage IOPS and disk throughput problems. In VCF Operations, heavy hitter dashboards are designed to isolate the consumers creating the highest demand on shared infrastructure resources. For storage troubleshooting, this dashboard identifies VMs producing significant I/O load, including IOPS and throughput. This is especially useful when a Fibre Channel datastore is reporting performance alerts because the datastore itself may show contention, but the root cause is often one or more high-demand VMs consuming disproportionate backend storage resources. The vSAN Health dashboard is not correct because the affected datastore is Fibre Channel, not vSAN. The vSphere Storage Inventory dashboard is useful for topology and inventory visibility, but it is not the best view for identifying the VM-level consumers causing IOPS and throughput pressure. The Storage Operations page is broader and less targeted than the Live heavy hitter view. Reference topics: VCF Operations Performance Dashboards, Storage Heavy Hitters, VM IOPS and Throughput Troubleshooting.

Windows Server Failover Cluster shared disks require coordinated access to shared block storage. vSAN supports Windows Server Failover Clusters by providing SCSI-3 Persistent Reservation support at the virtual disk level, which allows cluster nodes to arbitrate access to a shared disk resource. One supported approach is to use the vSAN iSCSI Target Service, which presents vSAN-backed LUNs to initiators and can be used for clustered workloads that require shared block access. Another supported approach is to configure a shared virtual disk using a VMware Paravirtual SCSI controller with physical bus sharing. Physical bus sharing allows multiple VMs to access the same shared virtual disk in a WSFC configuration where supported. Raw Device Mapping is not the vSAN ESA-native solution for this requirement. NFS v4.1 is a file datastore protocol, not a WSFC shared block disk mechanism. ''LSI SCSI controller per disk'' does not satisfy the required shared-disk bus sharing configuration.
