VMware 2V0-16.25 - VMware vSphere Foundation 9.0 Administrator

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.

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.

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.

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 avSAN Original Storage Architecture (OSA) cluster, the feature that provides themaximum storage space reductionisDeduplication and Compression.

Deduplication removes duplicate blocks across the cluster.

Compression further reduces the space used by unique blocks.

These are applied at thedisk group leveland are essential inVDI environmentswhere identical VM images consume space.

Why others are incorrect:

A. Disable Object Checksum→ Only reduces CPU overhead, not storage space.

C. Object space reservation→ Controls reserved capacity, not reduction.

D. Compression only→ Reduces space, but less than Deduplication + Compression combined.

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.

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.

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).
