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

The error:

“Internal Error: Failed to retrieve vim client”

occurs whenVCF Operations cannot establish a functional API session with vCenter. Thevim clientis the internal vSphere API client library used by VCF Operations to perform cluster actions such as modifying DRS settings, powering on/off workloads, or retrieving inventory.

When this error appears, VMware documentation identifies these common root causes:

Loss of connectivity between VCF Operations and vCenter

DNS resolution issues

Network interruption

Stale or expired authentication tokens

Credential mismatchIf the vCenter password was changed manually, VCF Operations may be unable to authenticate.

vCenter services restarting or unavailableIf vCenter backend services (vpxd, sts, etc.) are unstable, VCF Operations cannot establish a vim session.

Option A is incorrect—DRS automation state in the vSphere Client does not cause vim client retrieval errors.

Option B (vCenter overloaded by API requests) would cause timeouts, not a vim client initialization failure.

Option D (insufficient licensing) affects feature use, not API connectivity.

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.

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.

Before applying updates to a vCenter Server Appliance (VCSA), an administrator must validate that all vCenter services are healthy. VMware provides two supported and documented methods for checking vCenter service status:

1. Using the vCenter Appliance Shell

Running the command:

services-control --status

This command displays the status of all vCenter-related services (vmdird, vmcad, vpxd, vsan-health, etc.). It is the authoritative diagnostic tool embedded in the appliance for confirming whether services are running, stopped, or in a degraded state. This method is explicitly documented in vSphere 9.0 service management procedures.

This matchesOption B.

2. Using the vCenter Server Management Interface (VAMI)

Accessed at:

https:// :5480

The VAMI console provides a graphical interface underServices, showing the real-time health, status, and start/stop controls for all vCenter services. VMware documentation instructs administrators to review service status here before performing upgrades or maintenance operations.

This matchesOption C.

Incorrect Options Explained

A. vSphere performance charts→ These show workload data, not service health.

D. vim-top command→ Displays vSphere hosts’ runtime metrics, not vCenter services.

E. Running services.sh on ESXi DCUI→ vCenter doesnotrun ESXi services; this script is for ESXi hosts only.

In VMware Cloud Foundation 9.0 Automation, each VPC is governed by aVPC Service Profile, which defines the default network services applied to the VPC’s DHCP server—this includesDNS servers, NTP servers, DHCP lease values, and other network attributes. When a subnet is associated with a VPC and DHCP is enabled, the DHCP service inherits its DNS and NTP configuration from the VPC Service Profile.

In the scenario, virtual machines attached to the new VPC subnet receive an IP address, but not DNS or NTP settings. This indicates that the DHCP server is functioning correctly, but its service profile lacks DNS and NTP configuration. Updating thedefault VPC Service Profileallows the administrator to specify DNS resolver addresses and NTP time sources, which will then automatically be pushed to all DHCP-enabled subnets under that VPC.

Option B (changing to DHCP Relay) is incorrect because relay mode does not configure DNS/NTP—it delegates DHCP to an external DHCP server.

Option C (enable DNS/NTP passthrough) is not a feature of NSX DHCP.

Option D (changing connectivity mode) affects routing and service placement, not DHCP options.

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.

In VMware Cloud Foundation (VCF) 9.0 Automation, the visibility of debug-level information in Task Logs is controlled centrally by theProvider Administratorthrough theProvider Management portal. Debug logging is not enabled by default because it exposes verbose operational details intended primarily for troubleshooting. According to the VCF Automation architecture and operations model, advanced logging capabilities—including debug output—are gated behindfeature flags.

To enable debug-level information, the Provider Admin must navigate to:

Provider Management → Administration → Feature Flags → Display Debug Information

Once this flag is enabled, the system begins emitting additional diagnostic detail into Task Logs, improving insight into failures, orchestration flows, API calls, and service-to-service interactions. This aligns with VCF’s multi-tenant design, where only the Provider tier has permission to modify global settings that affect all Organizations.

Options A, C, and D are incorrect because Organization-level settings do not control system-wide logging, and the Events/Tasks or General Settings sections do not contain the mechanism for enabling debug output. Only theFeature Flagsection controls this capability.

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.

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.

In VMware Cloud Foundation (VCF) 9.0 usingdisconnected mode licensing, VCF Operations does not automatically synchronize license status with VMware’s cloud services. Instead, the administrator must periodically refresh the license file using amanual offline workflow. When the VCF Operations console reports that licenses have expired, it means the license entitlement in theVCF Business Services portalis out of date, and therefore VCF Operations cannot validate the current usage.

The VMware-documented offline licensing workflow requires the following steps:

Export the usage filefrom VCF Operations.This usage file contains consumption details needed to generate a new offline license.→C is correct.

Upload the usage file to the VCF Business Services consoleand generate a new offline license file.In disconnected mode, the Business Services portal is the only mechanism to create updated license entitlements.→D is correct.

Import the updated VCF license file into VCF Operations, specifically assigning it to theSDDC Manager.SDDC Manager is the system that validates and enforces licensing across workload domains, so the new license must be applied there—not only to a vCenter.→F is correct.

Options A and B do not affect license validation.

Option E is incorrect because workload-domain vCenter licensing is independent and not the root cause of VCF license expiration.

The error message com.vmware.esx.settings.daemon.software.scan_spec (reconstructed from the typo setungs_aaemon.sonware.scan_spec) is a specific failure generated by thevSphere Lifecycle Manager (vLCM)compliance engine on the ESXi host.

Cause - Removed Component:This error is a documented known issue in vSphere 8.x/VCF 5.x+, specifically occurring when an administrator hasremoved a componentfrom the Cluster Image that the system validates as "required" or "structural" for the host's hardware configuration (common with hosts using DPUs or specific OEM add-ons).

The Scenario:The mention of "High CPU ready times" likely implies the administrator attempted to streamline the host image byremovinga perceived "bloatware" component (like a vendor monitoring agent or unused driver) to improve performance.

The Result:When vLCM attempts to build the "Scan Specification" (scan_spec) to validate the host against this modified image, the internal struct validation fails because the removed component creates an invalid dependency state, throwing the Invalid field software_spec... or scan_spec exception.

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.

When deploying a new workload domain in VMware Cloud Foundation (VCF), only ESXi hosts that fully meetall pre-requisitesare displayed in the VCF Operations UI for selection. Although all six hosts appear in theUnassigned Host Inventoryin vCenter, VCF performs additional validation before making them selectable for workload domain deployment.

One of the mandatory requirements for any vSAN-enabled workload domain is that the ESXi hosts must be associated with aNetwork Pool configured for vSAN traffic. A network pool defines the host network configuration (VLANs, MTU, NIC mapping) used during domain deployment.

If the two missing hosts are associated with a network pool thatdoes not have vSAN traffic enabled, or are associated withno network pool at all, VCF willexcludethem from the workload domain deployment wizard. This is documented behavior: VCF filters out hosts when required network intents—such as vSAN—are not present.

Other options are incorrect:

A. Management port group enabled for vSAN traffic— vSAN shouldneverrun on the management PG.

B. FTT setting— Has no effect on host visibility; applies only after deployment.

C. Disk partitions— Affects vSAN disk claim but doesnotprevent host selection in VCF.

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 9.0 Operations,tags created inside VCF Operations do not automatically appear in vCenter. Tags must be explicitly synchronized ("pushed") to the selected vCenter instance before they become usable for VM tagging within vCenter. This is because VCF Operations maintains its own metadata store for tags, super metrics, groups, and policies.

The correct workflow is:

Create the tag in VCF Operations.

Push (synchronize) the tag to the appropriate vCenter instance.

The tag then appears in vCenter’sTags & Custom Attributessection.

Administrators can then assign the tag to VMs.

If the push step is skipped, the tag exists only inside VCF Operations and cannot be referenced by vCenter, which is exactly the symptom described:tag not found when attempting to assign it to a VM.

Option A is incorrect because Custom Groups do not affect vCenter tag visibility.

Option B is incorrect because tag synchronization is not tied to a specific vCenter version as long as the vCenter is officially supported by VCF 9.x.

Option D is irrelevant—VMware Tools has nothing to do with tag visibility.

When troubleshootingBGP peering issueson an NSX Edge Transport Node, VMware documentation directs administrators to examinerouting logs, because BGP failures are often caused by adjacency negotiation errors, authentication mismatches, keepalive/hold timer issues, or route-policy failures.

The NSX Edge CLI command:

get log-file routing follow

streams real-time routing logs, including BGP daemon logs (bfdd, routed, wdog) and provides detailed insight into:

BGP session establishment and teardown

Keepalive and hold timer exchanges

Neighbor state transitions

Route advertisement or rejection

Authentication mismatches

MTU or connectivity issues on TEP / uplinks

This is theonlycommand in the list that exposesdiagnostic-level BGP informationneeded to troubleshoot peering.

Option A (edge-cluster status) shows cluster membership only.

Option B (get logical-routers) shows logical router configuration, not BGP logs.

Option C (edge-cluster history state) is unrelated to routing.

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.

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.
