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

TheVCF Operations Orchestrator Plug-in for VMware vSphere Web Clientallows orchestration workflows directly in the vSphere Client.

However,only one vSphere instance can be integratedat a time with the vSphere Client via this plug-in.

This limitation ensures a consistent, single orchestration endpoint per vSphere Client environment.

Other options (8, 10, 15) apply to scaling of vCenter or data sources but not to the Orchestrator Plug-in integration.

VCF Operations requires that custom SSL certificates meet these requirements:

Certificates and private key must be inPEM format. (A)

Theserver certificate must be listed firstin the file. (D)

The file must include theserver certificate, private key, and full certificate chain(issuing/intermediate/root CA). (E)

Why others are wrong:

B. Server certificate last→ Incorrect, it must be first.

C. Cannot use SAN extension→ Incorrect, SAN is supported and recommended.

F. PFX format→ Not supported for VCF Operations.

Hardware abstraction in VMware virtualization:

Thehypervisor abstracts physical resources(CPU, memory, storage, networking) and presents them to VMs asstandardized virtual hardware.

This allows VMs to run independently of underlying physical devices, enabling features likevMotion and hardware independence.

Other options:

A. Encrypting data→ Security feature, not abstraction.

B. Isolating memory access→ Memory protection, not full abstraction.

C. Live migration between Intel and AMD→ Possible with compatibility modes, but not a direct definition of abstraction.

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.

ThevSphere Foundation 9.0 licensing modelusesper-core licensing.

Current license covers1024 cores.

Existing hosts =960 cores, leaving64 cores licensed.

Adding a96-core host→ 32 cores exceed the license.

Result:

The new host runs inevaluation mode.

If not licensed after the evaluation period, the host isdisconnected from vCenter.

Other options:

A. Limited to 64 cores→ Not how VMware licensing enforcement works.

B. Limited to 64 cores until license upgrade→ Incorrect; VMware does not partially disable cores.

D. No issue→ Incorrect; licensing compliance will cause issues.

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.

When creating acustom alert in VCF Operations, the final required step is:

Enable the alert in an Active Policy, so it applies to the target objects.

Without policy activation, the alert exists but will never trigger.

Other options:

A. Super metric→ Only required if monitoring a custom metric, not for standard alerts.

B. REST Notification Plugin→ Used for outbound integration, not triggering alerts.

C. Payload Template→ Used in notifications, not in core alert configuration.

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.

To allow a Content Library in vSphere Foundation to be accessed byother vCenter Server instances, it must bepublished.

Once published, other vCenters cansubscribeto the library.

Synchronization ensures subscribed vCenters receive updated templates and ISOs.

Other options:

A. Automatic synchronization→ Works only for subscribers, not for publishing.

B. Store on vSAN datastore→ Storage choice does not enable multi-vCenter access.

C. Store on NFS datastore→ Similar, datastore type does not matter.

To enableenhanced capabilities of Storage Operations for vSAN 9.0 in VCF Operations(Diagnostic Troubleshooting, Benchmarking, and Optimizing), administrators must complete several prerequisites that ensure vSAN health, performance, and permissions are properly set up.

Enable and start the vSAN Performance service in the target vCenter (B):

The vSAN Performance Service must be enabled for cluster-level monitoring.

This provides the telemetry data needed for diagnostic and benchmarking capabilities in VCF Operations.

Without enabling this service, no performance metrics can be collected.

Configure a vSAN account for the vCenter Integration Instance (C):

A dedicated vSAN service account must be configured so that VCF Operations can communicate with vCenter for vSAN data collection.

This ensures secure and role-specific access for monitoring operations.

Assign the credentials configured in the vCenter Integration instance to have access to vSAN objects (E):

The credentials used in the vCenter integration must have the required privileges to access vSAN objects (such as datastore, cluster objects, and health checks).

This ensures that VCF Operations can run diagnostics, benchmarking, and optimization functions without permission errors.

Why the other options are incorrect:

A. No configuration required, Run New Diagnostics is enabled automatically:❌Incorrect. Configuration is required before these advanced features can be enabled.

D. Assign the VCF Operations Service Account administrative rights to vSAN Objects:❌Too broad and not a best practice. Instead, specific rights via the vCenter integration account (option E) are recommended.

F. Open port 5989 on each VCF Operations node on which the vSAN adapter exists:❌Not required for enabling vSAN advanced diagnostics in VCF 9.0. vSAN operations rely on vCenter connectivity, not direct port 5989.

TheVM Storage Policy rulethat controlsdata redundancy in vSANisFailures to Tolerate (FTT).

Defines the number of hardware failures (host, disk, network) that vSAN can tolerate while maintaining data availability.

Configurations includeRAID-1 (mirroring),RAID-5/6 (erasure coding).

Other options:

B. Disk Stripes Per Object→ Defines performance striping, not redundancy.

C. Stripe Width→ Same as above, not redundancy.

D. Flash Read Cache Reservation→ Relates to caching performance, not redundancy.

To move a VM to another cluster:

Requirement: Zero downtime→ RequiresvMotion.

Challenge: Datastore not shared→ RequiresStorage vMotion.

The combined operation,Cross-Cluster vMotion with Storage vMotion, allows moving compute and storage at the same time, with no downtime.

Other options:

A. vMotion only→ Requires shared datastore, not available here.

B. Backup/restore→ Causes downtime, not acceptable.

D. Cannot be moved→ Incorrect; vMotion + Storage vMotion supports this.

When a newly installedESX hostcannot be reached and all basic network tests (gateway, DNS, hostname resolution) fail:

Thefirst troubleshooting stepis to confirm that themanagement network TCP/IP configuration(IP address, subnet mask, default gateway, DNS servers) is correct.

If this is misconfigured, the host will not communicate with vCenter or resolve names.

B. Verify DVS configuration in vCenter→ Requires host connectivity first.

C. Reinstall ESX→ Too drastic without confirming networking basics.

D. Disconnect/reconnect cable→ Less likely since VLANs/adapters are reported as connected.

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.

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.
