2V0-15.25 Sample Questions Answers

In VMware Cloud Foundation 9.0 Automation, every Organization requires a properly configured Networking Configuration for each Region in which it operates. This configuration step—performed by the Provider Administrator—creates the NSX Project corresponding to the Organization, enabling Namespace creation, VPC visibility, and workload provisioning.

The error “Failed to list VPC after selecting a region” combined with the absence of an NSX Project in NSX Manager is a direct indicator that the Organization’s Networking Configuration was never initialized. VCF Automation automatically creates the NSX Project only when the Provider Admin completes this step.

Option B is invalid because the Organization Administrator cannot create NSX Projects manually; they are system-generated during networking setup.

Option C is incorrect because role assignment affects administrative permissions, not NSX project creation.

Option D is also incorrect—the Organization Admin cannot create a VPC until the NSX Project exists.

When importing an existing vSphere environment into VMware Cloud Foundation (VCF) as a workload domain, several strict prerequisites must be met. One of the key requirements documented in VCF 9.0 is that allVMkernel adapters (vmk ports)used for vSAN, vMotion, management, or other system trafficmust have statically assigned IP addresses. DHCP-assigned VMkernel IPs arenot supportedfor VCF workload domain bring-up or import operations.

In the provided scenario, the environment includes:

vSphere 8.0 U3

A 3-node vSAN OSA cluster

Two VDS switches

VMkernel adapters using DHCP

Before VCF can successfully validate and import the environment, the administrator must convert these VMkernel interfaces tostatic IP addressing. VCF uses IPAM assumptions and deterministic host networking configurations; DHCP introduces variability incompatible with automated lifecycle operations.

Option A (consolidating VDS) is unnecessary—VCF supports multiple VDS configurations during import.

Option B (upgrading to vSphere 9.0) is not required for import.

Option D (convert OSA to ESA) is impossible pre-import and not required—VCF supports OSA clusters.

In VMware Cloud Foundation 9.0, publishing aVCF Operations Orchestratorworkflow to aVCF Automation project catalogrequires that the Organization has a valid integration withVCF Operations Orchestrator. The question states that the usercannot see the Workflows option under Content Hub, and theorganization is not a Provider Consumption Organization (PCO). According to the VCF 9.0 documentation, only organizations withVCF Operations Orchestrator integrationare allowed to publish workflows into the catalog. Both embedded and external orchestrator integrations must be configured depending on the environment. Ifno orchestrator (embedded or external)is integrated with the organization, workflows cannot be listed or published. This aligns with the documented VCF Automation and VCF Operations Orchestrator design requirements, which specify that workflow publishing is only available when the orchestrator instance is properly registered.

Additionally, user role permission issues could prevent workflow visibility, but the key blockers described in the scenario are the missing workflow section and the organization type. Because the organization isnot a PCO, advanced provider features—including workflow publishing—are disabled unless a proper orchestrator integration exists. Therefore, the two most likely causes are:

A:An external VCF Operations Orchestrator is not integrated with their Organization.

D:An embedded VCF Operations Orchestrator is not integrated with their Organization.

These two conditions directly match the documented behavior in VMware Cloud Foundation 9.0.

vDefend – Distributed Firewall is a security capability delivered byNSXwithin VMware Cloud Foundation. Although VCF components such as SDDC Manager, VCF Operations, and VCF Automation rely on licensing frameworks, the enforcement and activation ofNSX features—including Distributed Firewall—occur entirely withinNSX Manager.

To enablevDefend (Distributed Firewall), NSX Manager must detect a valid NSX license that includes security features. Without applying the correct license directly to NSX Manager:

The Distributed Firewall feature remains locked

vDefend cannot be enabled in workload domains

Security rules and micro-segmentation capability remain unavailable

VCF does not apply NSX security licensing at the SDDC Manager, VCF Automation, or VCF Operations layers. Instead, NSX Manager handles all feature entitlement checks internally.

Therefore, the new license must be installeddirectly in NSX Manager, under:

System → Licensing → NSX → Add License

Options A, C, and D are incorrect because none of those components control NSX feature activation.

In VMware Cloud Foundation 9.0,host commissioningis performed exclusively throughSDDC Manager, not from the vSphere Client. When expanding a vSAN cluster inside a workload domain, all ESXi hosts must first be placed in anUnassignedstate and thencommissionedin SDDC Manager before they can appear in the “Add Host” wizard of the vSphere Client. The message in the problem—“No unassigned hosts available with storage type VSAN. Commission hosts with physical NICs 0 & 1 to Add Host from UI”—indicates that SDDC Manager has not yet commissioned any suitable hosts with the required NIC layout.

VCF 9.0 documentation states that for workload domain expansion, hosts must be commissioned under:

SDDC Manager → Workload Domains → (Select WLD) → Hosts → Commission Hosts.

This validates hardware, storage type (such as vSAN ESA or OSA), NIC placement, and ensures the host is compatible with the domain’s configuration.

Options pointing to vSphere Client (A, D) or VCF Operations (B) do not perform the commissioning workflow. Therefore, the correct and verified answer isC, the only interface where host commissioning is officially supported.

To convert an existing vSphere environment into aVMware Cloud Foundation (VCF) 9.0 Management Domain, several prerequisites must be met as defined in the VCF 9.x documentation.

First,VCF 9.0 requires vSphere 9.0as part of its Bill of Materials (BOM). The uploaded VCF 9.0 documentation confirms that VCF 9.0 is built onvSphere 9.0, vCenter 9.0, and NSX versions that align with the 9.x stack. A vSphere 8.0 Update 3 environment isnot supportedas a foundation for a VCF 9.0 management domain; therefore, the administrator mustupgrade the entire vSphere platform to vSphere 9.0before VCF deployment.

(Reference: VCF 9.0 BOM — vSphere 9.0 is mandatory.)

Second, VCF management domain creation strictly requiresvSphere Distributed Switches (vDS). VCF doesnotsupportvSphere Standard Switches (VSS)for any management domain hosts. The VCF 9.0 design and deployment guides state that all ESXi hosts intended for a management domain must use vDS for management, vSAN, and vMotion networking. Therefore, the existence of a VSS must be corrected by deploying and configuring avSphere Distributed Switchand migrating host networking accordingly before Cloud Builder deployment.

Removing standalone hosts or removing a VSS from inventory isnot required. Only the hosts selected for the management domain need to be prepared.

Thus, the required changes are:

✔B. Upgrade vSphere 8.0 Update 3 to vSphere 9.0

✔C. Configure a vSphere Distributed Switch

These are the only changes explicitly required by VCF 9.0 documentation.

When activating avSphere Supervisor using VCF Networking with VPC, theSupervisor Workload Networkmust use aVPC Connectivity Profile. These profiles arescoped to an NSX Project, andcannot be consumed from the Default Project.

VCF Automation requires that:

Acustom NSX Projectbe used for VPC networking integrations.

TheDefault Projectcannot host Connectivity Profiles or VPC constructs intended for Supervisor activation.

Even though the administrator verified that a VPC Connectivity Profileexistsin NSX, the Supervisor wizard will not display it if:

The VPC Connectivity Profile belongs to adifferent project, or

The current selection is theDefault Project, which blocks visibility.

This exact behavior—empty VPC Connectivity Profile dropdown—is documented when attempting Supervisor activation under the Default NSX Project.

Option A (T0 active/active) affects North-South routing but does not hide VPC profiles.

Option B (Supervisor HA mode) does not impact network profile selection.

Option D (missing default VPC) is incorrect because the wizard is complaining aboutavailability of Connectivity Profiles, not VPC instances.

VMware Cloud Foundation 9.0 introduces a major architectural redesign that replaces the traditional SDDC Manager–centric domain management model with aunified Fleet Management architectureimplemented throughVCF Operations Fleet Manager. In this model, each Workload Domain operates withits own vCenter, but Enhanced Linked Mode (ELM) isremovedto improve isolation, reduce blast radius, and support multi-site scalability. As a result, administrators logged into the vSphere Client of the Management Domaincan no longer manage or expand clusters in other Workload Domains, which explains why the vSphere UI blocks the attempted expansion of WLD-02.

Fleet Manager becomes the new authoritative control plane for lifecycle, topology, host commissioning, and workload domain expansion. Only Fleet Manager maintains the fullglobal viewnecessary to orchestrate cluster addition operations across distributed vCenters and domains. Because WLD-02 is running VCF 9.0 and is fully fleet-aware, its expansion must occur throughVCF Operations Fleet Manager, not through the vSphere Client or legacy SDDC Manager workflows.

Options involving WLD-03 are invalid since that domain is running VCF 5.2.1, is isolated, and cannot participate in fleet-aware operations. SDDC Manager (A) is no longer the correct interface for VCF 9.0 domain expansion operations.

The vSphere Client “no healthy upstream” error is a classic indicator that one or morevCenter backend services are not running or responding, preventing the reverse proxy layer (envoy / nginx) from routing requests to the appropriate upstream services.

Two services in particular are known root causes:

A. vpxd service not running

vpxd is the core vCenter Server service responsible for inventory, host management, and client interaction. If vpxd is stopped, crashed, or restarting, the vSphere Client cannot communicate with backend APIs, resulting in the “no healthy upstream” condition.

B. SSO (vmware-stsd / identity service) not running

Authentication in vCenter depends on the SSO/Identity service. If SSO is unavailable, login sessions cannot be validated, and vCenter marks the upstream service as unhealthy.

Other options donotmatch the behavior:

C (Port 443 closed)would produce a connection failure, not the upstream error.

D (logging in with root)is fully supported and does not trigger this message.

E (vmware-rbd-watchdog)relates to backup/restore health, not core authentication/management planes.

In VMware Cloud Foundation, deletion of a workload domain requires that VCF Operations can correctly discover and process the NSX components attached to that domain. The workload domain delete workflow explicitly includes removal of the NSX Manager and NSX Edge components associated with the domain, unless those NSX components are shared.

In earlier and current VCF guidance, VMware state that NSX Edge clusters for a workload domain must be removed using the documented/VCF-aware method (for example, using the NSX Edge removal process referenced in KB 78635, not by deleting objects directly in NSX Manager). If an administrator deletes theNSX Edge cluster directly in NSX Manager, the VCF inventory and orchestration logic still “believes” the Edge cluster exists. When the workload domain delete workflow reaches the stage“Gather input for deletion of NSX component”, it queries NSX / internal state for Edge cluster data. Because the underlying object has been manually removed, the returned structure is null, which results in an internal“Cannot read the array length because "<locall9>" is null”style error.

Using theNSX Edge Cluster Deployment Removal Toolas per documentation keeps VCF and NSX in sync and is thesupportedpath, so option A is not the likely cause. Network pools and shared NSX Manager configurations do not match the specific NSX-component array/null condition described.

In VCF 9.0, when deployingVCF Automationusing the VCF Installer in aSimple Deployment Model, the appliance requirestwo IP addresses:

Primary IP– Management interface

Secondary IP– Required for service separation and internal routing for Automation services

VMware’s JSON schema for VCF Installer enforces this requirement. If the second IP is missing, incorrectly formatted, or placed under the wrong JSON section, the installer validation will fail immediately with a JSON schema error before deployment begins.

This is one of themost common causesof validation failure for VCF Automation deployment.

Option A (component binaries missing) produces abundle downloaderror, not JSON schema failure.

Option C (NSX Manager size = large) is allowed and does not break JSON validation.

Option D (separate vDS for vSAN) is allowed if defined correctly and also does not cause JSON schema failure.

TheGlobal Inventory List (GIL)is only available whenmulti-vCenter SSO domain linkingis configured. In VMware Cloud Foundation, themanagement domain vCenteris deployed first and becomes theroot vCenterfor global inventory data. For workload domains, their vCenter Servers must beregistered into the same SSO domainandlinkedwith the management-domain vCenter in order for the global inventory data (VMs, hosts, clusters, content libraries) to appear.

If a workload domain vCenter is not SSO-linked, it operates in its own identity domain, and thereforecannot access or present Global Inventory, resulting in exactly the symptom described: the management domain vCenter shows the GIL, while the workload domain vCenter does not.

Option B (Supervisor Management) relates to vSphere with Tanzu and has no impact on Global Inventory.

Option C (inventory sync) is incorrect—there is no manual sync required; GIL relies entirely on SSO linking.

Option D (VIDB) is not related to vCenter linking or inventory visibility; it is used by VCF Identity Broker.

Therefore, the reason the Global Inventory is missing from the workload domain vCenter is thatSSO/vCenter Linking has not been configured, which is required for federation across all VCF vCenters.

The"Remote Logging Not Configured"alarm in NSX Manager is a system-health alert indicating that one or more Transport Nodes (Edges or Hypervisors) or Management Nodes do not have a Syslog server defined.

NSX Node Profiles:In VMware NSX (and by extension VCF), the standard method to apply consistent administrative settings—such asSyslog Servers, NTP settings, and Core Dump configurations—across a fleet of nodes is to use anNSX Node Profile.

Configuration Path:The administrator should navigate toSystem > Fabric > Profiles > Node Profiles. Here, they can create or edit a profile that specifies the remote syslog server's IP/FQDN, port, and protocol.

Application:Once the Node Profile is applied to the NSX Management Cluster or Edge Clusters, the configuration is pushed to all respective appliances, clearing the alarm.

Why not A/B:Edge Cluster Profiles manage networking/BFD settings; Uplink Profiles manage NIC teaming and MTU.

In VCF 9.0, when adding a host to a vSAN ESA-enabled cluster, the hostmust be commissioned with a network pool that includes a vSAN network configuration. Network pools define host-level networking templates for VCF, including management, vSAN, vMotion, and overlay networks. A host commissioned with avMotion-only network pooldoes not have the required vSAN ESA network interfaces (vmk + NIC mapping) to join an ESA cluster.

Because the administrator successfully commissioned the new host but only using avMotion-only network pool, VCF correctly prevents the host from being added to the ESA cluster.

The required action is:

Reassociate the host with the correct network pool that includes the vSAN ESA network.

Option A (reinstall ESXi) is unnecessary; commissioning workflows can be redone.

Option C (manual vCenter configuration) is explicitly unsupported—VCF manages host networking.

Option D (reconfiguring the existing pool) is not correct because the new host must be associated with thesame network pool used by the existing ESA cluster, not change the pool definition itself.

Therefore, the precise and VMware-documented resolution isB.

In VMware Cloud Foundation (VCF) Automation, eachAutomation Regionmust be associated with adedicated NSX Local Manager. A single NSX Local Manager instancecannot be reused across multiple Automation Regions.

In the provided scenario:

The existing environment hasWLD1andWLD2, both sharingone NSX Local Manager.

Region-1 in VCF Automation already consumes this shared NSX Local Manager.

When creatingRegion-2, the interface shows“No results”when selecting an NSX Local Manager.

This behavior matches documented VCF Automation constraints:an NSX Local Manager can only be mapped to a single Automation Region. Once it is consumed by one region, it isnot availablefor any additional region.

To create a second region (Region-2), anew NSX Local Manager instancemust exist in the environment. The only supported method to obtain a new NSX Local Manager is todeploy a new workload domain, because NSX Local Manager is deployed as part of every VI Workload Domain.

Thus, the administrator mustdeploy a new (third) workload domain, which includes its own NSX Local Manager package, allowing Region-2 to be created successfully.
