2V0-15.25 Leak Questions

In VMware Cloud Foundation 9.0 Automation, the Provider Portal must have full visibility into the underlying VCF inventory—includingNSX Managers,clusters,regions,vCenters, andSDDC Manager objects—before new regions can be created for Kubernetes-based deployments (All Apps Orgs).

The issue described:

“The NSX Manager for the workload domain does not appear in the list of available NSX Managers”

occurs whenSDDC Manager is not integratedinto VCF Automation. Without this integration, VCF Automation cannot discover workload domains or their associated NSX Managers. As a result, when attempting to create a new region, the NSX Manager list is empty.

The required action is:

Add the SDDC Manager integration under VCF Automation → Provider Portal → Integrations.

This integration enables Automation to pull:

NSX Manager inventory

vCenter endpoints

Workload domain topology

Cluster details

Only after this integration is complete will the NSX Manager appear and allow region creation.

Option A and D (deploying new WLD or cluster) are unnecessary—inventory access is the problem, not resources.

Option B (triggering inventory sync) cannot work becauseno SDDC Manager integration exists.

Application Monitoring in VCF Operations uses Telegraf agents running inside virtual machines. These agents forward metrics to theCloud Proxy, which then sends them to the Operations analytics cluster. One of the most common reasons an agent stops reporting data—especially exactly24 hoursafter deployment—isclock drift or time mismatchbetween the VM (running the Telegraf agent) and the Cloud Proxy.

VCF Operations enforcesstrict timestamp validation. If the timestamps from the agent are outside the acceptable drift window, the Cloud Proxyrejectsincoming data as invalid. In this case, the Telegraf agents appear installed and functional, but no new metrics are received by the analytics engine.

This is a well-known issue documented in VMware Aria/VCF Operations agent-based monitoring, where:

Agents send metrics with local system time.

Cloud Proxy enforces time validation to prevent corrupt metric ingestion.

A drift >5 minutes commonly results inzero data collectiondespite healthy connectivity.

Options B and C cannot stop data flow after exactly 24 hours; they would preventinitialcollection. Option D (virtual hardware/tools compatibility) affects VM operations butnotTelegraf metric time-stamp validation.

In VMware Cloud Foundation 9.0,all host commissioning operationsare performed throughVCF Operations, not through vSphere Client, Cloud Builder, or the VCF Installer. Once VCF is deployed, Cloud Builder is no longer used, and the VCF Installer is for lifecycle and bundle management—not for host workflows. The vSphere Client also cannot commission hosts because host commissioning is a foundational VCF workflow requiring hardware validation, storage type checks, NIC checks, HCL conformance, and version compatibility.

The error message provided:

“Hosts must be unassigned, commissioned with at least one physical NIC and the same storage type… and the ESX version must be compatible…”

is a standard VCF 9.0 validation message shown whenno commissioned hostsmatching the workload domain requirements exist. VMware documentation states that hosts must be commissioned under:

VCF Operations → Fleet Management → Hosts → Commission Host

Here, VCF validates:

Storage type (vSAN ESA, vSAN OSA, NFS, FC, etc.)

Network pool membership (matching the WLD plan)

ESXi version compatibility with the Management Domain baseline

NIC mapping and certifications

Until hosts are commissioned, they cannot appear in the workload domain creation wizard.

Thus, the correct method to commission hosts isD. Using VCF Operations.

In VMware Cloud Foundation 9.0, supplemental storage such as NFS is fully supported for workload domains when configured correctly. When an NFS datastore mounts successfully in vSphere but users cannot write data, the issue almost always lies in theexport permissions on the NFS server. vSphere will allow mounting a read-only NFS export, but write operations will fail silently at the VM or guest OS level.

VCF documentation confirms that ESXi requires explicitread/write export permissions, typically configured per-host or by IP subnet, on the NFS server. Even if network connectivity and VM-level access appear healthy, incorrect server-side permissions prevent ESXi from executing write operations.

Option A is incorrect because NFS servers are not validated by the HCL for write capability.

Option B (rebooting the host) is unnecessary and unrelated to permission enforcement.

Option D (MTU mismatch) may cause performance issues, not write-access failures.

Thus, the next troubleshooting step is to verify that the ESXi hosts haveread/write accesson the NFS share, makingCthe correct answer.
