VMware Advanced VMware Cloud Foundation 9.0 Storage 認定 3V0-23.25 試験問題 (Q11-Q16):

質問 # 11
An administrator is tasked with designing a highly available vSAN ESA two-node cluster for a remote VMware Cloud Foundation (VCF) workload domain. The solution should be able to survive the failure of any disk group in addition to a host failure without data loss.
What is the minimum total number of nested fault domains required for the design?

A. 0
B. 1
C. 2
D. 3

正解：A

解説：
The minimum total number of nested fault domains is six. In a two-node vSAN design, site disaster tolerance is provided through host mirroring between the two data hosts, with a witness maintaining quorum. The requirement adds another layer: the solution must also survive a disk group or local storage failure in addition to a host failure. vSAN's two-node host mirroring rule states that each data host must have at least three disk groups, or three disks in a storage pool, to use the rule. In ESA, the equivalent construct is disks in the storage pool rather than OSA-style disk groups. Because there are two data hosts, and each data host requires three nested placement units, the minimum total is 3 + 3 = 6 nested fault domains. Four would not meet the host-mirroring rule requirement, and two would only represent the two hosts without local storage fault isolation. Reference topics: vSAN Two-Node Cluster, Host Mirroring, Nested Fault Domains, vSAN ESA Storage Pool Placement.

質問 # 12
An administrator has deployed a three-host vSphere cluster with a small amount of VMFS storage and wants to add additional capacity from a vSAN ESA cluster located in the same vCenter Server.
When the administrator selects the vSphere cluster and navigates to the Configure tab, the Datastore Management option is missing under the vSAN section.
What prerequisite must be met before the administrator can mount the remote datastore?

A. A fourth host must be commissioned for the vSphere cluster.
B. vSAN must be enabled on the non-vSAN cluster to act as a compute cluster.
C. The vSAN Storage cluster must have a minimum of 80% free space.
D. The vSphere cluster must be deployed to a different VCF Workload Domain.

正解：B

解説：
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. Reference topics: vSAN Compute Cluster, Remote vSAN Datastore, Datastore Management, vSAN Storage Cluster.

質問 # 13
A Solutions Architect is calculating the network bandwidth saturation for a specific VMDK under heavy write load in a vSAN ESA cluster. The available Top-of-Rack switch throughput is limited to 25 GbE.
The VM generates 500 MB/s of raw write data.
The architect evaluates two different Storage Policies applied to this specific VM:
```
[SPBM Configuration Options]
Policy A: Failures To Tolerate: 1 (RAID-1 Mirroring)
Policy B: Failures To Tolerate: 1 (RAID-5 Erasure Coding)
```
How do these different SPBM policies directly alter the actual "on-the-wire" network traffic profile for vSAN, and what is the impact on the 25 GbE fabric? (Select all that apply.)

A. Both policies consume zero network bandwidth for reads when the "Site Locality" feature is enabled.
B. Policy B (RAID-5) significantly reduces the network bandwidth multiplier compared to RAID-1, because the erasure coding algorithm spreads parity overhead (1.33x) rather than duplicating the full dataset.
C. Policy A (RAID-1) generates 1000 MB/s of total backend network traffic (a 2.0x multiplier) because the DOM Client must simultaneously send the 500 MB/s data payload to both Mirror 1 and Mirror 2 across the network.
D. Switching from Policy A to Policy B doubles the network traffic overhead because RAID-5 requires a
4th parity node.
E. vSAN ESA compresses the data BEFORE it leaves the host (DOM Client level); therefore, if the VM generates highly compressible data (e.g., 2:1 ratio), Policy B will only push ~332 MB/s across the network, preserving the 25 GbE switch buffers.

正解：B、C、E

質問 # 14
A VI Admin is planning the expansion of a 3-node vSAN cluster to a 6-node vSAN cluster. The 3- node cluster is currently operating near maximum safe capacity due to the strict "Host Rebuild Reserve" threshold.
```
[Log Snippet: vmkernel.log - Capacity Daemon]
2026-11-20T10:00:00Z WARN vsan-dom - Host Rebuild Reserve active: 33%
of Raw Capacity locked.
2026-11-20T12:00:00Z INFO vpxd - Cluster expansion complete. Host
count: 6.
2026-11-20T12:05:00Z INFO vsan-dom - Host Rebuild Reserve recalculated:
[ ? ]%
```
How does the physical expansion of the cluster mathematically alter the "Host Rebuild Reserve" percentage, and what is the direct impact on usable VM capacity?

A. The reserve percentage remains fixed at 33% to comply with the FTT=1 storage policy, meaning usable capacity scales linearly but overhead remains high.
B. The reserve percentage increases to 50% because a 6-node cluster inherently carries a higher statistical risk of dual-host failures.
C. The required reserve percentage automatically decreases from 33% down to approximately 16%; this releases a significant portion of previously "locked" storage on the original hosts back into the usable VM capacity pool.
D. The log indicates that Host Rebuild Reserve is disabled automatically upon reaching 6 nodes because Distributed Resource Scheduler (DRS) handles capacity allocation above the 4-node threshold.

正解：C

質問 # 15
An Operations Engineer is attempting to expand a VCF 9.0 Workload Domain by adding a new ESXi host via the SDDC Manager UI.
```
[SDDC Manager - Pre-Check Validation]
Status: FAILED
Error Code: VSAN_HEALTH_CHECK_FAILED
Details: "Network Performance Proactive Test detected bandwidth below
threshold."
[UI - SDDC Manager Capacity View]
Current Cluster: 3 Hosts (75% Consumed)
Target: Add esx-04
```
Why does SDDC Manager explicitly execute and mandate the "vSAN Network Performance Test" before allowing a new host to join the live cluster? (Choose 2.)

A. The test injects multicast traffic to measure the switch buffer depth; if the switch drops packets, the host is deemed unsuitable for Stretched Clustering.
B. The test runs a physical memory scan on the new host to determine if it can run vCenter.
C. The test calculates the deduplication savings on the new host to ensure it matches the existing capacity.
D. The Proactive Network test verifies that the new host's physical bandwidth can actually support the background resync (rebalance) that will immediately trigger when the 4th host is added to the
75% full cluster.
E. SDDC Manager treats vSAN as the core infrastructure backbone; adding a host with a degraded network link (e.g., faulty SFP negotiating at 1GbE instead of 25GbE) would destabilize the existing quorum.

正解：D、E
