2V0-16.25 VMware vSphere Foundation 9.0 Administrator Questions and Answers

The requirement is to followleast privilegewhile granting specific VM operations:

Power on/off virtual machines

Open consoles

Create snapshots

TheVirtual Machine Power Userrole is the correct out-of-the-box role, as it includes all these privileges without granting unnecessary administrative access.

Other roles:

Administrator (A):Grants full environment control → too broad.

Virtual Machine Console User (B):Limited to console access, cannot power on/off or snapshot.

Virtual Machine User (C):Can interact with VMs but lacks snapshot privileges.

InVCF Operations for Logs, administrators can analyze logs using queries, fields, and charts. A key feature is the ability toview the value range of a specific field.

When a log query is executed, results appear in theEvents table.

Each field shown in the Events table is interactive.

Byclicking on a field in the Events table, administrators can drill down into the data tovisualize its value distribution (range), typically in the form of a histogram or grouped data set.

This provides insight intowhat values are present and how frequently they occur, which is useful for troubleshooting, anomaly detection, and refining queries.

Why not the other options?

A. Click the pencil in the Manage Fields pane→ Used toedit or extract fields, not visualize ranges.

C. Click on the field in Manage Fields→ Displays field definitions and settings, not real-time value ranges.

D. Click on the field in the Field Table→ The Field Table lists defined fields but does not provide value range visualization.

To ensure that only specific users can manage VMs in a specific VMware vCenter folder, the following three steps are required:

Create a new role in vCenter with VM management permissions(Answer B):You must define a custom role tailored to managing VMs, which includes permissions such as powering on/off VMs, editing VM settings, and accessing consoles. This role must include the appropriate privileges under the “Virtual machine” category in vCenter permissions.

Apply the role to the specific vCenter folder(Answer C):The custom role needs to be applied directly to the target vCenter folder. This enables scope-based access control, where permissions are applied only to VMs within that folder.

Assign the new role to the appropriate users/groups(Answer A):After creating the role and applying it to the folder, the role must be associated with the correct users or groups. This step uses the vCenter Server's identity source integration to assign roles.

Why the other options are incorrect:

D. Add the identity source to vCenter:This is a prerequisite step for any role assignment but is not directly required in this specific scenario if the identity source is already configured.

E. Create a datastore cluster:This is unrelated to managing VM access. Datastore clusters pertain to storage management and are not involved in user permissions or role assignments.

To satisfy both IT and executive requirements:

IT team→ Needsdetailed technical metrics, which are available throughOut-of-the-Box dashboards in VCF Operations. (A)

Executives→ Need acustom KPI-focused dashboard, with summaries and high-level visibility. This can be shared via aURL linkthat always shows the latest data. (B)

Why others are incorrect:

C. Custom dashboard in VCF Operations for Logs→ Logs are not KPI-focused performance metrics.

D. Out-of-the-Box dashboards in VCF Automation→ VCF Automation is not designed for KPI reporting.

The capability inVMware Cloud Foundation (VCF) Operationsthat directly enablesmonitoring and optimizationof aVMware vSphere Foundation (VVF) environmentisCapacity Analytics.

Capacity Analyticsprovides real-time and predictive insights intoresource utilization, capacity forecasting, and optimization.

It analyzeshistorical and real-time utilization datato predict future workload demands, enabling administrators to proactively plan expansions or right-size workloads.

This includeswhat-if scenario modeling,workload optimization, andresource reclamationto ensure workloads are efficiently placed, avoiding bottlenecks and waste.

Why not the other options?

A. Intelligent Alerts→ Provides proactive alerts and recommendations but is more focused onissue detection and notification, not optimization.

C. Log Insight Integration→ Enables log analysis and troubleshooting, not capacity optimization.

D. Infrastructure Visibility→ Provides monitoring and observability but does not performpredictive optimization.

ForConfidential Computing in vSphere 9.0:

Hardware Memory Isolation: RequiresAMD SEV-SNP (Secure Encrypted Virtualization – Secure Nested Paging)orIntel TDX (Trust Domain Extensions)enabled in the host BIOS and supported by ESXi. (C)

Trusted Hosts: Must usevSphere Trust Authority (vTA)to ensure that only verified, secure hosts run Confidential VMs. The VM must have theConfidential Computing flagset. (E)

Other options:

A. VM Hardware version 22→ Required for new features, but Confidential Computing specifically requires hardware + vTA.

B. TPM 2.0 guest OS attestation→ Not used for Confidential Computing, that’s host-based attestation.

D. Encrypted vMotion Required→ Recommended for secure VMotion, but not sufficient for Confidential Computing.

InVCF Operations for Logs(formerly vRealize Log Insight):

ThePrimary Nodeis responsible forcoordinating the overall functioning of the cluster, including configuration management and directing traffic.

Worker/Data Nodeshandle log ingestion and query execution.

Replica Nodeprovides HA for the Primary Node but does not act as the main coordinator.

Two supported methods exist for adding widgets toVCF Operations for Logs dashboards:

From Explore Logs– Create a widget (e.g., query result) and selectAdd to Dashboard. (B)

Dashboard Design Pane– Use the design interface todrag and drop widgets. (C)

Other options:

A. Clone widget from existing dashboard→ Not a supported method.

D. Import widget in design pane→ Import is for dashboards, not individual widgets.

E. Management Pack Builder→ Not related to Logs dashboard widgets.

ForDisconnected mode licensingin vSphere Foundation:

Administrators must manuallyexport a registration file, upload it to theVCF Business Services console, and thenimport the license fileback into VCF Operations.

This process must be repeatedevery 180 daysto maintain license validity.

Other options:

A. Switch to Connected mode once every 365 days→ Incorrect; 180-day requirement.

C. License is perpetual→ Not correct; subscription-based license requires refresh.

D. Provide internet connection every 180 days→ Violates security restriction (Disconnected mode is required).

In this scenario, anetwork failureoccurred on a host, and VMs on that host didnot restart on other hosts, even thoughHA and DRS were enabled.

This indicates thatvSphere HA detected an isolation event(the host lost network connectivity) but tookno action, because theHost Isolation Response was disabled.

Normally, with Host Isolation Response set to "Power Off and Restart VMs," HA restarts affected VMs on surviving hosts.

Since powering off a host manually triggers a restart correctly, the failure here was specific toisolation behavior.

Other options:

B. Affinity rule "should run on"→ Would still allow HA restart elsewhere if isolation occurred.

C. DRS not enabled→ DRS only balances load; HA is responsible for restarts.

D. HA not enabled→ Contradicts the scenario (HA was enabled).

The requirement is for acentralized platformto monitorperformance, health, and capacityacross theentire VMware vSphere Foundation (VVF) environment.

VCF Operations

Providesend-to-end performance monitoring, capacity management, and health analyticsacross vCenter, ESXi, vSAN, and NSX.

IncludesFinOps and Capacity Planning,performance diagnostics, andAI-driven troubleshootingfor faster remediation.

This is the primary component for monitoring theentire VCF environment.

VCF Operations for Networks

Extends observability tonetwork operationsby monitoring NSX health, VPCs, and network flows.

Providestraffic summaries, alerts, and network capacity metrics.

Integrated with VCF Operations to ensure acomplete platform-wide viewof health and performance.

Why not the others?

VCF Operations for Logs→ Focused onlog management, troubleshooting, and diagnostics(not holistic performance/capacity monitoring).

vSphere Supervisor→ ProvidesKubernetes namespace and workload management, not centralized performance/capacity monitoring.

To deploy theVCF Operations for Logs OVA appliance:

ThevSphere Clientis used to deploy.ovaand.ovftemplates directly into a vCenter environment.

After deployment, the appliance can be configured and integrated with VCF.

Other options:

A. VCF Fleet Management→ Used for multi-instance management, not OVA deployment.

C. VCF Automation→ Provides automation workflows, not appliance deployment.

D. VCF Operations→ Monitoring and analytics platform, not used for OVA installs.

The requirements:

QA must not lose performance during contention→ QA must haveguaranteed resources, soFixedis correct.

Marketing can use leftover resources when QA is idle→ Marketing must beScalable, so it can borrow resources from QA’s allocation when available.

Other options:

A. Both Fixed→ Marketing would not be able to use QA’s unused resources.

C. QA Scalable, MKT Fixed→ QA would lose guaranteed resources, violating requirements.

D. Not possible→ Incorrect; VMware supports this configuration.

In aVMware vSphere Foundation (VVF) deploymentwithvCenter Supervisor Namespaces enabled, the method for creating VMs inside a Supervisor Namespace relies on thevSphere VM Service.

TheVM Serviceexposes VMs as Kubernetes-native objects that are managed usingkubectl.

Administrators (or DevOps engineers with appropriate permissions) must write aVM YAML manifest file, which specifies parameters such as apiVersion, kind: VirtualMachine, spec.imageName, spec.className, spec.storageClass, and spec.networkInterfaces.

The YAML manifest is thenapplied with kubectlto the Supervisor context.

This approach is documented as the supported method:

"As a DevOps engineer, provision a VM and its guest OS in a declarative manner by writing VM deployment specifications in a Kubernetes YAML file."

Why the other options are incorrect:

B. Deploy using the vSphere Client→❌The vSphere Client is used to configure Namespaces, permissions, and VM classes, butactual VM creation in Supervisor Namespaces is done via kubectl + YAML.

C. Use VCF CLI to deploy the VM→❌VCF CLI (kubectl vsphere login) is used only to authenticate and obtain context, not to create VMs.

D. Log in to VCF Automation Service Broker→❌This is used for vRealize Automation/Aria Automation integration, not for direct Supervisor Namespace VM creation.

InVCF Operations (vRealize Operations) cluster architecture:

ThePrimary Nodehandles administration and management.

TheReplica Nodeprovidesfault tolerance for the Primary Node, ensuring that administrative functions remain available in case of failure.

Data Nodeshandle data collection and analytics.

Witness Node→ Not a role in VCF Operations; relevant to vSAN clusters.

Thus, the node type providingfault tolerance for administrative functionsis theReplica Node.
