VMware Advanced VMware Cloud Foundation 9.0 Storage 認定 3V0-23.25 試験問題 (Q16-Q21):

質問 # 16
A VCF Architect is calculating the performance TCO (Cost per IOPS) difference between upgrading a legacy SAN environment and deploying a new vSAN ESA HCI Cluster.
The architect examines the log output during a simulated application stress test that saturated the backend capabilities of both topologies.
```
[Log Analysis: vpxd.log - Congestion Events]
# Traditional SAN Cluster
2026-12-01T10:00:15Z WARN vpxd - [Storage] Datastore 'SAN-Tier1' queue
depth 64/64 full. Host I/O delayed.
# vSAN ESA Cluster
2026-12-01T10:15:22Z WARN vpxd - [vSAN] Component congestion on ESXi-
08. vSAN DOM applying localized backpressure.
2026-12-01T10:15:23Z INFO vpxd - [vSAN] DRS migrating VM 'App-DB' to
ESXi-02 to access uncongested storage path.
```
How does the HCI Operational Model provide a TCO and performance advantage for handling extreme utilization peaks, as demonstrated in this log? (Select all that apply.)

A. In a 3-tier SAN, the LUN queue is a rigid choke point; scaling performance requires physically upgrading the SAN controllers. In HCI, the queue is distributed across all NVMe drives on all hosts, naturally providing massively higher aggregate queues.
B. The operational cost of expanding the "queue depth" in HCI is effectively zero because it scales automatically as physical hosts and NVMe drives are added to the environment.
C. Traditional SANs cannot use vMotion to resolve storage congestion because the storage bottleneck is centralized at the array level, impacting all hosts connected to that LUN.
D. The ESA log output indicates a failure of the Deduplication engine, which forces the system to buy additional software licenses to process the I/O.
E. HCI allows performance troubleshooting to leverage standard compute resources. If an HCI host is congested, vSphere DRS can simply vMotion the VM to another host with available storage and compute cycles.

正解：A、B、C、E

質問 # 17
A Solutions Architect is designing the hardware bill of materials (BOM) for a new VCF 9.0 implementation. The customer has a strict budget and wants to reuse some existing legacy hardware, specifically 10 GbE network switches and SATA SSDs.
```
[Proposed Architecture Diagram]
Network: 10 GbE Top-of-Rack Switches
Host Storage: 2x 400 GB NVMe (Intel Optane) + 6x 3.84 TB SATA SSDs
```
The architect must choose between deploying vSAN OSA or vSAN ESA for this specific BOM.
Which TWO statements accurately describe the compatibility and compliance of this hardware with the two architectures? (Choose 2.)

A. This hardware profile is strictly non-compliant with vSAN ESA, which explicitly requires a minimum 25 GbE network fabric and an All-NVMe storage pool.
B. vSAN OSA fully supports this configuration by utilizing the NVMe devices for the Cache Tier and the SATA SSDs for the Capacity Tier, connected via the 10 GbE network.
C. The 10 GbE network is a hard blocker for both OSA and ESA in VCF 9.0; the architect must upgrade to 100 GbE switches to deploy any HCI solution.
D. vSAN ESA supports the SATA SSDs for the capacity tier, but only if they are formatted with the VMFS- L filesystem prior to the cluster bootstrap.
E. vSAN ESA can support this hardware if the SATA SSDs are bypassed and the environment uses the
10 GbE network for "vSAN Direct" mode only.

正解：A、B

質問 # 18
Which vSAN feature ensures data availability across sites?

A. Snapshot
B. RAID 0
C. Clone
D. Stretched Cluster

正解：D

質問 # 19
An administrator is working on a VMware Cloud Foundation (VCF) Workload Domain that was configured to use vSAN for principal storage. The administrator wishes to create and configure a datastore cluster to host tenant VMs using that vSAN backed storage across multiple clusters, mixed OSA and ESA, in the domain.
What should the administrator consider?

A. vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.
B. When using vSAN as the underlying datastore, an administrator must create the datastore cluster via vCenter APIs, include the vSAN datastore(s) in it, enable Storage DRS, and ensure the VM Storage Policies reference the appropriate vSAN-capable datastore.
C. A datastore cluster can combine different storage types, such as vSAN, FC, and NFS datastores, as long as they are in the same vCenter; Storage DRS will treat them uniformly.
D. When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.

正解：D

解説：
vSAN datastores are not managed through datastore clusters and Storage DRS in the same way as traditional VMFS or NFS datastore collections. A vSAN cluster exposes a distributed vSAN datastore, and VM placement, resilience, space efficiency, and compliance are controlled through vSAN Storage Policy Based Management rather than Storage DRS. The scenario also includes mixed vSAN OSA and vSAN ESA storage across clusters, which introduces an additional compatibility concern. vSAN OSA and vSAN ESA datastores are different architectures and are not combined into a single datastore- cluster construct for uniform Storage DRS placement. A datastore cluster should not combine different storage architectures such as vSAN, Fibre Channel, and NFS because Storage DRS assumes similar, interchangeable datastore resources. Creating a datastore cluster through APIs does not make vSAN datastores supported in this model. Therefore, the administrator should consider that vSAN datastores are not supported in datastore clusters and should use vSAN storage policies and appropriate datastore selection instead. Reference topics: vSAN Datastores, Storage Policy Based Management, Datastore Cluster Requirements, vSAN OSA and ESA Compatibility.

質問 # 20
An Operations Engineer is deploying a vSAN Stretched Cluster across two datacenters (Site-Alpha and Site-Beta). The network architecture uses a Layer 3 topology.
The engineer configures the vSAN VMkernel interface (vmk2) on the hosts:
```
# Site-Alpha Host Configuration (esx-a-01)
vmk2 IP: 10.10.10.11 / 24
vmk2 Gateway: 10.10.10.1
# Site-Beta Host Configuration (esx-b-01)
vmk2 IP: 10.20.20.11 / 24
vmk2 Gateway: 10.20.20.1
# Witness Host Configuration
vmk1 IP: 10.30.30.11 / 24
vmk1 Gateway: 10.30.30.1
```
The vSAN health check fails with the error "Host cannot communicate with one or more other nodes in the vSAN cluster." Based on the intersection of vSAN networking and Stretched Cluster mechanics, which of the following statements accurately diagnose the routing failure and define the required solution? (Select all that apply.)

A. The engineer must configure static routes on the ESXi hosts so that traffic leaving vmk2 bound for the
10.20.20.0/24 (Site-Beta) and 10.30.30.0/24 (Witness) subnets is directed to the 10.10.10.1 gateway.
B. The default gateway set on a standard ESXi host applies to the Management network (vmk0). By default, vmk2 has no inherent default gateway, meaning vSAN traffic cannot route out of the local subnet.
C. Stretched Clusters explicitly require Layer 2 adjacency between Site-Alpha and Site-Beta; this Layer 3 topology is unsupported and must be redesigned.
D. Enabling "vSAN Traffic" on the default management vmk0 interface will resolve the issue by utilizing the host's existing default routing table.
E. The system is failing because the Witness host does not have Jumbo Frames (MTU 9000) enabled, which is a hard requirement for all vSAN Stretched Cluster nodes.

正解：A、B
