3V0-23.25 Practice Questions

The design requires four hardware corrections. First, RAID-6 with FTT=2 requires six fault domains or hosts because RAID-6 erasure coding must place data and parity components across enough independent hosts to tolerate two failures. Therefore, four hosts are insufficient and the host count must increase to at least six. Second, Storage Traffic Separation requires sufficient physical NICs to support separate storage and non-storage traffic paths. With two distributed switches and redundant uplinks, the design must increase to four 25 GbE NICs per host. Third, vSAN ESA requires at least 128 GB of host memory; the provided 96 GB is below the minimum. Fourth, NVMe devices attached to a SATA/SAS/NVMe Tri-mode controller are not supported for vSAN storage pools. The documentation states that vSAN supports SAS and SATA devices on Tri-mode controllers, but NVMe devices must be directly connected to PCIe or use a supported NVMe design. The CPU count does not need to increase because 24 cores satisfies the stated vSAN ESA minimum in the referenced design guidance.

Deploy ESX 9.x

Configure to use NVMe storage

Deploy vCenter 9.x

Deploy the VCF Installer Appliance

Download binaries for the installation

Deploy VCF 9.x using existing components as building blocks

Add additional components

The sequence begins with deploying ESX 9.x on the blade hosts because the hosts are the physical foundation for the future management domain. Since there is no local storage beyond the operating system and the external array supports NVMe/TCP only, the hosts must then be configured to use NVMe storage before vCenter is deployed. This provides the required shared datastore for the vCenter deployment and for later VCF management component placement. After the NVMe storage is accessible, vCenter 9.x is deployed to manage the ESX hosts and form the existing vSphere building block. The convergence process then moves into the VCF workflow: deploy the VCF Installer Appliance, download the required binaries to the installer appliance, and deploy VCF 9.x by using the existing vCenter and ESX hosts as starting building blocks. Because Aria Operations is not currently deployed, VCF Installer deploys the required missing components during the converge process, and remaining additional components are added after the core platform deployment is complete.
