2V0-15.25 Exam Dumps - VMware Certified Professional - VMware Cloud Foundation 9.0 Support

A Comprehensive and Detailed Explanation: When enabling vSphere Supervisor with NSX Classic (using the traditional NSX-T Data Center networking stack rather than the newer NSX VPC mode), the vSphere Workload Management wizard filters the list of available NSX Edge Clusters to ensure they are explicitly designated for use with Kubernetes workloads.

The "WCPReady" Tag Requirement: The primary mechanism vCenter uses to identify a valid, compatible Edge Cluster for Workload Management is a specific tag on the NSX Edge Cluster object. This tag must be WCPReady (case-sensitive).

Symptoms: If this tag is missing—which often happens if the Edge Cluster was created manually in NSX Manager rather than through the SDDC Manager automation—the validation process will fail to find any usable clusters. This results in the specific error message: "No valid edge cluster for VDS [UUID]", or simply an empty list of compatible clusters in the wizard.

Resolution: The administrator must log in to the NSX Manager, navigate to System > Fabric > Nodes > Edge Clusters, select the target cluster, and manually add the tag WCPReady (often with the scope "Created for", though the tag itself is the critical filter).

Why other options are incorrect:

B: Large Edge nodes are actually a requirement for vSphere Supervisor (Small/Medium are typically unsupported for this role), so deploying them as Large would make the cluster compatible, not incompatible.

C: vSphere Supervisor fully supports Distributed Connectivity (connecting directly to the VDS), so Central Connectivity is not a hard requirement causing this specific error.

D: While AVI (NSX Advanced Load Balancer) is a supported load balancer, the "No valid edge cluster" error occurs during the Edge Cluster discovery phase, preceding the load balancer configuration.

VMware Cloud Foundation 9.0 Operations manages credentials for integrated components such as vCenter Server through its internal password vault. When administrators modify passwordsdirectly on the component—such as manually changing thevCenter rootpassword—VCF Operations is no longer able to authenticate using its stored credentials. As a result, any password rotation or update operation initiated through VCF Operations fails during the validation step.

The error"Failed to authenticate with the guest operating system using the supplied credentials"is a direct symptom of this condition. VCF Operations attempts to log in to vCenter using thepreviously stored credential, which no longer matches the actual root password. Documentation describes this as an "out-of-sync credential state," and the resolution is to performpassword remediationto re-synchronize VCF Operations with the system.

Option A (password complexity) is irrelevant because complexity is validated only after authentication.

Option C (vCenter down) would generate connectivity errors, not authentication errors.

Option D (SSH disabled) does not prevent password rotation because VCF Operations uses VMware Tools guest operations, not SSH, for authentication.

In VMware Cloud Foundation 9.0 with vSAN ESA, storage policies must match the capabilities of the existing cluster. The scenario describes a5-node vSAN ESA clusterwhere the vSAN Default Storage Policy isRAID-1 (FTT=1). The administrator attempts to apply a2 Failures – RAID-6policy, which ESA supportsonly on clusters with at least 7 nodes. Because the cluster has only five nodes, the policy fails immediately—this is expected and documented in the vSAN ESA design specifications.

Since RAID-6 is not an option and capacity is low, the administrator must look for a method to reclaim storage usage without requiring additional nodes or unsupported policy changes. Converting VMs fromthick provisioning to thin provisioningis a safe and effective mitigation approach. Thin provisioning reduces consumed space by allowing disks to grow only as needed, immediately recovering unused blocks. This is a standard vSAN-supported method to temporarily alleviate capacity pressure.

Enabling encryption (A) or compression (D) doesnotreduce capacity usage retroactively and may actually increase overhead. Using RAID-5 (B) is also not possible because RAID-5 requiresat least 6 ESA-enabled hosts.

The status"Node Not Ready"in the NSX Manager UI (specifically in theConfiguration Statecolumn of the Edge Transport Nodes view) indicates that the NSX Manager has failed to push or validate the necessary configuration to the Edge VM.

Check Uplink Network Configuration (Option C):This is the most common cause for a "Node Not Ready" state during deployment or operation. For an Edge Node to be "Ready" (Success/Up), it must have a validTransport Nodeconfiguration, which includes theUplink Profile,IP Pool(for TEPs), and mapping to theFastpath Interfaces(N-VDS). If the uplink configuration is missing, incorrect, or the management plane cannot communicate with the edge to apply it, the node remains in a "Not Ready" state.

Why not Option A?While an Edge must be in anEdge Clusterto beutilizedby a Tier-0 Gateway, a standalone Edge Node should still report a status of "Success" (Configuration) and "Up" (Node Status) if it is healthy. Adding a "Not Ready" (unhealthy/unconfigured) node to a cluster will not fix the underlying configuration issue.

Why not Option D?Missing CPU reservations typically lead to a"Degraded"status or service crashes (Dataplane down), but "Node Not Ready" is the specific indicator of an incomplete or stalled configuration workflow, usually tied to the transport/uplink setup.

When upgrading fromVCF 5.0 to VCF 9.0, the upgrade workflow requires that theSDDC Manager be upgraded firstbefore any other component bundles (vCenter, ESX, NSX) become visible. This is explicitly stated in the VMware Cloud Foundation upgrade process:the upgrade bundles for the management domain components are dependent on the SDDC Manager version. The online depot will not present the 9.0 upgrade bundles for vCenter, ESX, or NSX until the SDDC Manager itself has reached the target major version (in this case, 9.0).

This is because SDDC Manager contains the updatedLifecycle Management (LCM)engine and updatedbundle manifests, which are required to understand, download, and orchestrate the remaining component upgrades. Attempting to download the other bundles without upgrading SDDC Manager first is not supported.

Options B and D (download tools) are incorrect because the issue isnot that the bundles are missing from the depot, but that SDDC Manager 5.x cannot interpret 9.0 component bundles. Option C (upgrade to 5.2 first) is also incorrect because the VCF 5.x → 9.x upgrade path is directly managed by the upgrade planner once SDDC Manager is upgraded.

Thus, the correct resolution is toupgrade the SDDC Manager to 9.0, after which the remaining component bundles will become available.
