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

After successfully deploying theVCF Installer appliance, and ensuring ESXi hosts are powered on and meet prerequisites, thenext stepis to:

Launch the VCF Installer deployment wizard, which guides administrators through host onboarding, vCenter deployment, and cluster setup forvSphere Foundation.

Other options:

A. Enable SSH on all ESX hosts→ Not required unless troubleshooting.

C. Install SDDC Manager using VCF Installer→ Only applies to full Cloud Foundation, not vSphere Foundation deployment.

D. Manually deploy vCenter Server Appliance→ The Installer wizard automates this.

For an8-node vSAN OSA cluster, the administrator needs a storage policy that:

Tolerates2 host failures, and

Providesmaximum usable capacity.

RAID-5/6 (erasure coding)is more capacity-efficient than RAID-1 mirroring.

To tolerate2 failures, the correct policy isRAID-5 with FTT=2.

RAID-1 (mirroring) would consume far more capacity, reducing usable space.

Other options:

A. 1 failure - RAID-1→ Only tolerates one failure.

C. 3 failures - RAID-1→ Provides higher resilience but uses much more capacity, not maximum efficiency.

D. 1 failure - RAID-5→ Tolerates only one failure.

The administrator wants toproactively manage performance degradationduring peak times without overwhelming the IT team.

The correct method is tocreate a custom alert with specific metric, threshold, and duration(A).

This ensures alerts are triggered only when sustained performance issues occur, reducing noise.

B. Default alert settings→ Too generic, may cause alert storms.

C. Custom dashboard→ Useful for visualization but not proactive alerting.

D. Notify during off-peak hours→ Defers the issue, not proactive.

To configureService Discovery for Linux Guest OSin VCF Operations using anon-root user:

Activate Service Discoveryin thevCenter instanceto start discovery operations. (B)

Enable Use Sudoin the Service Discovery instance so the non-root account can run necessary privileged commands. (E)

Other options:

A. Activate Use Sudo in vCenter instance→ Wrong, this is configured in Service Discovery.

C. Activate in NSX instance→ Not applicable; Service Discovery integrates with vCenter.

D. Deactivate Use Sudo→ Opposite of required security setting.

TheVCF Operations for Logs capabilitymost useful forroot cause analysis and troubleshootingisLog Querying.

Allows searching, filtering, and correlating log events to diagnose issues.

Log Forwarding (A)→ Sends logs elsewhere, not analysis.

Alerting (B)→ Notifies about issues but does not provide investigation details.

Dashboarding (C)→ Provides visualization, but root cause analysis requiresqueries.

ForvSAN ESA (Express Storage Architecture), minimum requirements differ from OSA:

25GbE NICsare required to handle high-performance traffic. (C)

NVMe PCIe flash devicesmust be used for storage. (D)

128GB Memory minimumper host is required. (F)

Other options:

A. 10GbE→ Only supported in vSAN OSA, not ESA.

B. 256GB Memory→ Recommended for large workloads, not minimum.

E. SAS SSDs→ Not supported in ESA; NVMe required.

InVCF Operations, when monitoring metrics like CPU demand across ESX hosts, includinghistorical usage and forecast data, the best visualization is aTrend view.

Trend viewsdisplay data over time, showing both past and predicted future behavior.

This makes them ideal forcapacity planning, performance forecasting, and demand analysis.

Table (A)→ Shows raw values but lacks predictive visualization.

Distribution (B)→ Useful for comparing values across objects but not for time-based or forecasted trends.

Text (C)→ Displays static values or metrics, not historical/forecasting data.

Thecore benefit of server consolidation using VMware server virtualizationis the ability to runmultiple independent virtual machines (VMs)on asingle physical host.

This increases hardware utilization, reduces physical server sprawl, and cuts operational costs.

A. Load balancing→ Achieved through features like DRS, not basic server consolidation.

C. Ransomware protection→ Achieved through security features and backups, not consolidation.

D. Automating application clusters→ A benefit of orchestration tools, not consolidation.

Thet-shirt sizing model(Small, Medium, Large) forvCPU allocationis an example ofslab-based pricing.

Base rate slabsallow administrators to define different ranges (slabs) of resource usage with associated rates.

In this case, vCPUs are grouped into ranges (1–2, 3–4, 5–8), and charges are applied per slab.

Other options:

A. Base rate storage per GB→ Applies to storage, not CPU.

C. Base rate CPU per GHz→ Charges by GHz usage, not vCPU count.

D. Base rate CPU per vCPU→ Flat per vCPU, no slab/tier-based flexibility.

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.

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.

WhenSupervisor is enabled:

It providesSupervisor Namespaces, which grant DevOps teamssecure, policy-based accessto vSphere resources (VMs, storage, networking) through Kubernetes tooling.

This enforcesboundaries and quotasfor compute/storage consumption.

Other options:

B. VM backup via ConfigMaps→ Not a feature of Supervisor.

C. vSphere Replication between namespaces→ Not a Supervisor function.

D. Granting administrator access to vCenter system namespace→ Violates least-privilege security.

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.

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.

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).
