3V0-23.25試験無料問題集「VMware Advanced VMware Cloud Foundation 9.0 Storage 認定」
An administrator is responsible for a VMware Cloud Foundation (VCF) Private Cloud and has been tasked with identifying which storage model is supported in the different VCF Workload Domains.
Drag and drop the Support Status of each storage model on the left to each type of Workload Domain on the right.

Explanation:
The support status is based on the VCF 9.0 Principal and Supplemental Storage model. vSAN ESA is supported as principal storage for the Management Domain default cluster, Management Domain additional clusters, and Virtual Infrastructure Workload Domains. A vSAN Storage Cluster is not supported for the Management Domain default cluster, but it is supported as principal storage for Management Domain additional clusters and VI Workload Domains. NFS storage supports principal and supplemental usage when the protocol is NFS v3; the table states "Principal (NFS v3)" and "Supplemental (NFSv3 and NFSv4.1)" across all three domain categories, so NFS v3 maps to Both. iSCSI is supported only as supplemental storage across the Management Domain default cluster, Management Domain additional clusters, and VI Workload Domains. This follows the VCF distinction where principal storage is used during workload domain or cluster creation, while supplemental storage is added after creation for workloads or data-at-rest use cases such as templates, backups, and ISO images. Reference topics: Storage Models, Principal Storage, Supplemental Storage, vSAN ESA, vSAN Storage Cluster, NFS, iSCSI.
An administrator is responsible for a VMware Cloud Foundation (VCF) Private Cloud and has been tasked with identifying and explaining the different Fibre Channel (FC) Storage Area Network (SAN) components within a VCF Workload Domain cluster.

Explanation:
LUN Masking = A security process performed on the storage array by which specific storage components are hidden to prevent unauthorized access to data; Datastore Cluster = A collection of shared resources with a shared management interface that enables resource allocation policies; SAN Fabric = A dedicated high-performance network infrastructure for storage devices; Datastore = A manageable storage entity used as a repository for Virtual Machine files including log files, scripts, configuration files and virtual disks; Host Bus Adapter (HBA) = Added to an ESX host server to allow the host access to the dedicated storage area network; Zoning = A security process completed on the Storage Area Network to ensure only certain devices can communicate with each other.
These definitions describe the core components of a Fibre Channel SAN design in a VCF Workload Domain. LUN masking is performed on the storage array and controls which hosts can see specific LUNs, preventing unauthorized access to storage. A datastore cluster is a collection of datastores managed as a shared resource pool, allowing placement and balancing policies through Storage DRS. A SAN fabric is the dedicated high-performance network that interconnects ESX hosts, Fibre Channel switches, and storage arrays. A datastore is the vSphere logical storage container where VM configuration files, virtual disks, logs, and related files reside. A Host Bus Adapter is the physical or virtual adapter in the ESX host that connects the host to the Fibre Channel storage area network.
Zoning is performed on the Fibre Channel fabric and controls which initiators and targets can communicate. Together, zoning and LUN masking provide layered access control, while datastores and datastore clusters provide the vSphere consumption model. Reference topics: Fibre Channel SAN Concepts, SAN Fabric, Zoning, LUN Masking, VMFS Datastores, Datastore Clusters.
An administrator has been tasked with suggesting storage models for a new VMware Cloud Foundation (VCF) Private Cloud. The following information has been provided:
* All existing implementations of VMware vSphere use the existing third-party block-based storage solution.
* The block-based storage solution only has sufficient scale, capacity and IOPS to cater for the new workload storage requirements.
* There is a dedicated and highly resilient storage area network connecting hosts to the provided block-based storage.
* There are 5 existing hosts with enough CPU and RAM resources and resilient Host Bus Adapters (HBAs) to cater for the new workload resource requirements only.
* There is sufficient budget to purchase some hardware, however the solution must re-use the existing hardware where possible.
The administrator suggests the following high-level solution:
* Single VCF Instance with a single Workload Domain.
* Deploy 4 new servers to create a Management Domain.
* Repurpose the 5 existing servers to create a single cluster in the Workload Domain.
Which two storage models should the administrator recommend? (Choose two.)

A clustered legacy application is scheduled for decommissioning at the end of the month. While in use, it stored application and quorum data on a pair of vSAN iSCSI Target LUNs.
After the vSAN iSCSI Target Service is disabled, what will happen to the existing targets and LUNs?

An administrator is tasked with deploying a VMware Cloud Foundation (VCF) Workload Domain that meets the following requirements:
* vSAN ESA as principal storage
* RAID-6 with FTT=2
* Support for Storage Traffic Separation
The administrator is provided the following hardware to perform the task:
* Four ESX hosts, each host contains:
* 24 CPU cores
* 96 GB memory
* Two 25GbE network NICs
* 12 NVMe devices 4 TB each, connected to a single SATA/SAS/NVMe Tri-mode controller What four changes must the administrator make to the hardware before deploying the new Workload Domain?

An administrator is monitoring a vSAN ESA backed workload domain that is dedicated for running AI inferencing. When the administrator navigates to the Storage Performance dashboard in VMware Cloud Foundation Operations, the performance dashboard shows:
* High backend write latency ( > 8 ms)
* Low read latency ( < 1 ms)
* Normal network throughput
* Disk Group Health = Green
Based on the readings above, what would be the explanation?
* High backend write latency ( > 8 ms)
* Low read latency ( < 1 ms)
* Normal network throughput
* Disk Group Health = Green
Based on the readings above, what would be the explanation?
