VMware 2V0-15.25 Online Practice Questions and Exam Preparation

VMware 2V0-15.25 Online Questions & Answers

• Question 1:

  An administrator is troubleshooting network connectivity issues on a VMware ESX host configured with a dedicated VMware vSAN vSphere Distributed Switch (vDS) port group. The VMware vSAN vDS port group has two physical adapters and two uplinks assigned. After a failure of the active physical adapter, the vSAN vDS connection over the vSAN network was lost. What is the cause of the issue?

  A. The vSAN storage policies are misconfigured.
  B. VLAN tagging is not correctly configured on the vDS.
  C. A physical adapter is set to "Not Used" in the vDS configuration.
  D. The vDS failover policy does not allow fallback.
  C. A physical adapter is set to "Not Used" in the vDS configuration.

  ---

  In vSAN ESA or OSA networking configured through a dedicated vSphere Distributed Switch (vDS), each vSAN vmkernel port must have at least one Active physical uplink available at all times. The scenario describes a vDS with two physical adapters and two uplinks, but after failure of the active uplink, vSAN traffic was lost. This only occurs when the second physical NIC is not actually assigned to the vSAN port group --typically because its uplink is set to "Unused".

  In such a misconfiguration:

  vSAN traffic only uses the single active uplink.

  When that uplink fails, vSAN has no failover path, causing immediate connectivity loss. Option A (storage policies) does not affect network uplink behavior. Option B (VLAN tagging) could cause connectivity failure but would not suddenly break only after an uplink failure.

  Option D (failover policy not allowing fallback) affects recovery order, not immediate redundancy.

• Question 2:

  An administrator is responsible for managing a VMware Cloud Foundation (VCF) fleet. The following information has been provided about the VCF fleet configuration:

  The VCF fleet consists of a single VCF instance with a single management domain and a single workload domain.

  VCF Automation has a single Organization for VM Apps configured with a VCF Cloud Account for the workload domain.

  The administrator has been tasked with creating a new Organization for All Apps to support the developers need to deploy Kubernetes-based applications in a new region in a workload domain.

  The administrator attempts to create a new region through the VCF Automation Provider Portal but the VMware NSX manager for the workload domain does not appear on the list of available NSX managers.

  What action must the administrator complete to resolve the issue?

  A. Deploy an additional VCF workload domain cluster.
  B. Trigger an inventory synch in VCF Operations fleet management.
  C. Add the SDDC Manager integration for the VCF instance.
  D. Deploy a new VCF workload domain.
  C. Add the SDDC Manager integration for the VCF instance.

  ---

  In VMware Cloud Foundation 9.0 Automation, the Provider Portal must have full visibility into the underlying VCF inventory--including NSX Managers clusters regions vCenters,,,, and SDDC 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 when SDDC Manager is not integrated into 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 because no SDDC Manager integration exists.

• Question 3:

  An administrator has a vSphere 8.0 update 3 environment with the following configuration:

  A 3-node vSAN cluster

  A vSphere Standard Switch (VSS)

  Several standalone ESX hosts in the vCenter inventory

  They want to convert this vSphere environment into a new VMware Cloud Foundation (VCF) 9.0 management domain.

  Identify two changes they will need to make before converting this vSphere environment into a VMWare Cloud Foundation (VCF) Management domain? (Choose two.)

  A. Remove the vSphere Standard Switch from the vCenter Inventory.
  B. Upgrade vSphere 8.0 Update 3 to vSphere 9.0.
  C. Configure a vSphere Distributed Switch.
  D. Remove the standalone hosts from the vCenter inventory.
  B. Upgrade vSphere 8.0 Update 3 to vSphere 9.0.
  C. Configure a vSphere Distributed Switch.

  ---

  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 9.0 as part of its Bill of Materials (BOM). The uploaded VCF 9.0 documentation confirms that VCF 9.0 is built on vSphere 9.0, vCenter 9.0, and NSX versions that align with the 9.x stack. A vSphere 8.0 Update 3 environment is not supported as a foundation for a VCF 9.0 management domain; therefore, the administrator mustupgrade the entire vSphere platform to vSphere 9.0 before VCF deployment.

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

  Second, VCF management domain creation strictly requires vSphere Distributed Switches (vDS). VCF does not support vSphere 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 a vSphere Distributed Switch and migrating host networking

  accordingly before Cloud Builder deployment.

  Removing standalone hosts or removing a VSS from inventory is not required. Only the hosts selected for the management domain need to be prepared.

  Thus, the required changes are:

  Option B: Upgrade vSphere 8.0 Update 3 to vSphere 9.0

  Option C: Configure a vSphere Distributed Switch

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

• Question 4:

  An administrator is attempting to log into the vCenter using the vSphere Client but receives an error stating "no healthy upstream". What are two possible causes for this? (Choose two.)

  A. The vpxd service is not running.
  B. The SSO Service is not running.
  C. Port 443 is not opened between the local machine and the vCenter.
  D. The administrator logged in with the root account.
  E. The vmware-rbd-watchdog service is not running.
  A. The vpxd service is not running.
  B. The SSO Service is not running.

  ---

  The vSphere Client " no healthy upstream " error is a classic indicator that one or more vCenter 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:

  Option 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.

  Option 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 do not match the behavior:

  Option C: (Port 443 closed) would produce a connection failure, not the upstream error. Option D: (logging in with root) is fully supported and does not trigger this message. Option E: (vmware-rbd-watchdog) relates to backup/restore health, not core authentication/management planes.

• Question 5:

  An administrator is troubleshooting an issue relating to VMware Cloud Foundation (VCF) Automation. While troubleshooting, the administrator realizes that debug-level information is not displayed in the VCF Automation Task Log. How would the Administrator enable debug-level information in the Task Log?

  A. Enable "display debug information" in the Administer > Settings section of the Organization Management portal.
  B. Enable "display debug information" in the Administration > Feature Flag section of the Provider Management portal.
  C. Enable "display debug information" in the Administration > Events and Tasks section of the Provider Management portal.
  D. Enable "display debug information" in the Administration > General Settings section of the Provider Management portal.
  B. Enable "display debug information" in the Administration > Feature Flag section of the Provider Management portal.

  ---

  In VMware Cloud Foundation (VCF) 9.0 Automation, the visibility of debug-level information in Task Logs is controlled centrally by the Provider Administrator through the Provider 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 behind feature 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 the Feature Flag section controls this capability.

• Question 6:

  An administrator has observed that the vSphere Global Inventory is only available from the management domain vCenter. The Global Inventory is not available from the workload domain's vCenter. Why is the "Global Inventory" missing from the workload domain's vCenter?

  A. VCF SSO and vCenter Linking have not been configured.
  B. Supervisor Management has not been enabled.
  C. An inventory sync was not run following the workload domain creation.
  D. An external VIDB instance has not been configured.
  A. VCF SSO and vCenter Linking have not been configured.

  ---

  The Global Inventory List (GIL) is only available when multi-vCenter SSO domain linking is configured. In VMware Cloud Foundation, the management domain vCenter is deployed first and becomes the root vCenter for global inventory data. For workload domains, their vCenter Servers must beregistered into the same SSO domain and linked with 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.

• Question 7:

  An administrator is preparing to perform maintenance on a VMware vCenter Server Appliance (VCSA) in a VMware Cloud Foundation (VCF) 9.0 management domain. Before proceeding, the administrator wants to validate service health from the appliance shell. Which command should the administrator run?

  A. vpxd-service --status
  B. services-control --status
  C. vimtop
  D. esxtop
  B. services-control --status

  ---

  In VMware Cloud Foundation environments, verifying vCenter service health prior to maintenance (patching, reboot, certificate operations, or lifecycle workflows) is a required best practice because VCF orchestration depends on stable vCenter services.

  The supported and authoritative method from the VCSA appliance shell is the services-control utility.

  Running:

  services-control --status

  returns the current state of all relevant services (for example, vpxd, vmdird, sts, and other VCSA components), allowing the administrator to confirm that services are running and not in a failed or stopped state before beginning maintenance.

  Option A is not a standard supported service-health command for VCSA in this context. Option C (vimtop) is used for observing vCenter process-level utilization rather than presenting a clear running/stopped service list. Option D (esxtop) is an ESXi host performance tool and does not apply to VCSA service validation.

• Question 8:

  An administrator logs into the VMware NSX Manage UI and observes a "Remote Logging Not Configured" alarm for each NSX Management node. What is a possible reason for this issue?

  A. Update the NSX Edge Cluster Profile to configure a remote logging server.
  B. Update the NSX Uplink Profile to configure a remote logging server.
  C. Update the NSX Node Profile to configure a remote logging server.
  D. Update the NSX Configuration Profile to configure a remote logging server.
  C. Update the NSX Node Profile to configure a remote logging server.

  ---

  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 as Syslog Servers, NTP settings, and Core Dump configurations--across a fleet of nodes is to use an NSX 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 Option A/B:Edge Cluster Profiles manage networking/BFD settings; Uplink Profiles manage NIC teaming and MTU.

• Question 9:

  An administrator logs into the vSphere client to check the health of a cluster. An alert appears on the cluster stating, "vSphere HA host status".

  The administrator toggles vSphere HA off and on and the following error appears on the host "A general system error occurred: Failed to start fdm service on host".

  What is the cause of this issue?

  A. The vmware-fdm service is disabled on the ESX host.
  B. The vmware-fdm vib is missing from the ESX host.
  C. vSphere HA Admission Control settings are not configured correctly.
  D. vSphere HA startup policy is not configured correctly.
  B. The vmware-fdm vib is missing from the ESX host.

  ---

  vSphere High Availability (HA) depends on the FDM agent (Fault Domain Manager) that runs on every ESXi host in the cluster. When an administrator enables HA on a cluster, vCenter automatically installs or updates the vmware-fdm VIB on each participating ESXi host. This VIB contains the HA agent binaries and is mandatory for HA services to start.

  The error encountered:

  "A general system error occurred: Failed to start fdm service on host" is a classic and well-documented symptom of a missing or corrupted vmware-fdm VIB. When vSphere HA is toggled off and on, vCenter attempts to reinstall or restart the FDM agent; if the VIB is not present, HA cannot deploy successfully, and the FDM service fails to start.

  Why the other answers are incorrect:

  Option A: The vmware-fdm service is disabledESXi does not allow manual disabling of this system service in normal operations. If the service fails to start, the root cause is usually the absence or corruption of the VIB--not a disabled service.

  Option C: Admission Control settings not configured correctlyAdmission Control errors affectVM failover capacity, not the ability to start FDM services.

  Option D: HA startup policy not configured correctlyThere is no per-host HA startup policy that prevents FDM from starting.

• Question 10:

  An administrator has been tasked with expanding an existing VMware Cloud Foundation (VCF) workload domain by adding a new cluster. The VCF fleet has the following configuration:

  1.

  Three workload domains, including the management domain are configured.

  2.

  The management domain (WLD-01) and one of the workload domains (WLD-02) are running VCF 9.0.

  3.

  The other workload domain (WLD-03) is running VCF 5.2.1 and is an isolated workload domain.

  When attempting to perform the required steps using the vSphere Client UI the cluster cannot be added to the WLD-02 workload domain.

  What step should the administrator perform to complete the workload domain expansion?

  A. Use the SDDC Manager UI to create the cluster in WLD-02.
  B. Use the SDDC Manager API to create the cluster in WLD-03.
  C. Use the vSphere Client UI to create the cluster in WLD-03.
  D. Use the VCF Operations Fleet Manager UI to create the cluster in WLD-02.
  D. Use the VCF Operations Fleet Manager UI to create the cluster in WLD-02.

  ---

  VMware Cloud Foundation 9.0 introduces a major architectural redesign that replaces the traditional SDDC Manager-centric domain management model with a unified Fleet Management architecture implemented through VCF Operations Fleet Manager. In this model, each Workload Domain operates with its own vCenter, but Enhanced Linked Mode (ELM) is removed to improve isolation, reduce blast radius, and support multi-site scalability. As a result, administrators logged into the vSphere Client of the

  Management Domain can 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 full global view necessary 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 through VCF 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 (Option A) is no longer the correct interface for VCF 9.0 domain expansion operations.
