In VMware Cloud Foundation 9.0 Operations,tags created inside VCF Operations do not automatically appear in vCenter. Tags must be explicitly synchronized ("pushed") to the selected vCenter instance before they become usable for VM tagging within vCenter. This is because VCF Operations maintains its own metadata store for tags, super metrics, groups, and policies.

The correct workflow is:

Create the tag in VCF Operations.

Push (synchronize) the tag to the appropriate vCenter instance.

The tag then appears in vCenter’sTags & Custom Attributessection.

Administrators can then assign the tag to VMs.

If the push step is skipped, the tag exists only inside VCF Operations and cannot be referenced by vCenter, which is exactly the symptom described:tag not found when attempting to assign it to a VM.

Option A is incorrect because Custom Groups do not affect vCenter tag visibility.

Option B is incorrect because tag synchronization is not tied to a specific vCenter version as long as the vCenter is officially supported by VCF 9.x.

Option D is irrelevant—VMware Tools has nothing to do with tag visibility.

When upgrading fromVCF 5.0 to VCF 9.0, the upgrade workflow requires that theSDDC Manager be upgraded firstbefore any other component bundles (vCenter, ESX, NSX) become visible. This is explicitly stated in the VMware Cloud Foundation upgrade process:the upgrade bundles for the management domain components are dependent on the SDDC Manager version. The online depot will not present the 9.0 upgrade bundles for vCenter, ESX, or NSX until the SDDC Manager itself has reached the target major version (in this case, 9.0).

This is because SDDC Manager contains the updatedLifecycle Management (LCM)engine and updatedbundle manifests, which are required to understand, download, and orchestrate the remaining component upgrades. Attempting to download the other bundles without upgrading SDDC Manager first is not supported.

Options B and D (download tools) are incorrect because the issue isnot that the bundles are missing from the depot, but that SDDC Manager 5.x cannot interpret 9.0 component bundles. Option C (upgrade to 5.2 first) is also incorrect because the VCF 5.x → 9.x upgrade path is directly managed by the upgrade planner once SDDC Manager is upgraded.

Thus, the correct resolution is toupgrade the SDDC Manager to 9.0, after which the remaining component bundles will become available.

VMware Cloud Foundation 9.0 introduces a major architectural redesign that replaces the traditional SDDC Manager–centric domain management model with aunified Fleet Management architectureimplemented throughVCF Operations Fleet Manager. In this model, each Workload Domain operates withits own vCenter, but Enhanced Linked Mode (ELM) isremovedto improve isolation, reduce blast radius, and support multi-site scalability. As a result, administrators logged into the vSphere Client of the Management Domaincan 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 fullglobal viewnecessary 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 throughVCF 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 (A) is no longer the correct interface for VCF 9.0 domain expansion operations.

In VMware Cloud Foundation (VCF) Automation for All Apps, avSphere Namespacecan span multipleSupervisor Zones. However, workloads—including catalog item deployments—canonlybe deployed into zones that are explicitlyassigned to that Namespace. The user in the scenario successfully deploys intozone1andzone2, which confirms that those zones are correctly associated with the Namespace.

The failure to deploy intozone3, while deployments into the other zones work, strongly indicates thatzone3 is not part of the Namespace configuration.

This behavior matches how Supervisor Zones function:

A zone must beadded to the Namespacein Supervisor configuration.

If the zone is not associated,VCF Automation will not present it as an eligible deployment location, and deployment into that zone fails.

Option A and D (project roles) are incorrect because insufficient permissions would prevent deploymentinto any zone, not a single missing zone.

Option B (Namespace Class) is irrelevant because Namespace Classes define resource limits, not which Supervisor Zones the Namespace is mapped to.

vDefend – Distributed Firewall is a security capability delivered byNSXwithin VMware Cloud Foundation. Although VCF components such as SDDC Manager, VCF Operations, and VCF Automation rely on licensing frameworks, the enforcement and activation ofNSX features—including Distributed Firewall—occur entirely withinNSX Manager.

To enablevDefend (Distributed Firewall), NSX Manager must detect a valid NSX license that includes security features. Without applying the correct license directly to NSX Manager:

The Distributed Firewall feature remains locked

vDefend cannot be enabled in workload domains

Security rules and micro-segmentation capability remain unavailable

VCF does not apply NSX security licensing at the SDDC Manager, VCF Automation, or VCF Operations layers. Instead, NSX Manager handles all feature entitlement checks internally.

Therefore, the new license must be installeddirectly in NSX Manager, under:

System → Licensing → NSX → Add License

Options A, C, and D are incorrect because none of those components control NSX feature activation.

To diagnose and resolve the intermittent performance and connection drop issues with the supplemental iSCSI storage, the administrator should focus on network layer consistency and health, particularly regarding packet size (MTU) and delivery (TCP).

Examine the iSCSI VMkernel port for TCP retransmissions (Action B - Diagnose):"Intermittent" connection drops and slow I/O are classic symptoms of packet loss or fragmentation issues. By examining the ESXi network stats (e.g., using esxtop key n or viewing vSphere performance charts) forTCP retransmissions, the administrator can confirm if packets are being dropped or lost in transit.Checksum offload errorscan also indicate issues where the NIC hardware is incorrectly validating packets, causing the OS to drop them. This step identifies theroot cause(packet loss/corruption).

Ensure all ESX hosts have the VMkernel port MTU set to 9000 (Action E - Resolve):For high-performance storage traffic like iSCSI in a VMware Cloud Foundation environment, it is best practice to useJumbo Frames (MTU 9000)end-to-end (Host -> Switch -> Storage Array).

The symptom thatsomehosts are affected suggestsconfiguration driftwhere those specific hosts might be set to a different MTU (e.g., 1500) or are mismatched with the physical network/target (which is likely set to 9000 for performance).

An MTU mismatch (e.g., Target sending 9000-byte frames to a Host/Switch expecting 1500) typically results in the "Do Not Fragment" (DF) bit causing packet drops, leading to the reported connection drops and retransmission delays. Ensuring a consistent MTU of 9000 across the fleet resolves this and aligns with VCF performance standards.

Note: Option A (CHAP) is for authentication security, not performance. Option C (Update network plugin) is a lifecycle task but less likely to be the immediate fix for "some hosts" having intermittent drops compared to the common issue of MTU mismatch. Option D (MTU 1500) would resolve drops if the physical network doesn't support Jumbo Frames, but would degrade performance, making E the preferred resolution for a "performance" storage tier.

When replacing certificates in VMware Cloud Foundation (VCF) Operations, the system performs strict certificate chain validation. The error shown:

“Certificate chain validation failed due to 'Signature does not match’”

indicates that VCF Operations attempted to validate the presented certificate chain but detected that the server certificate did not correctly match the signing CA certificate. This occursmost commonly when the administrator pastes the server certificate and CA root/intermediate certificates into the wrong fields during import.

VCF requires the certificate bundle to be uploaded in the correct format:

Server certificate→ Server Certificate field

Intermediate certificates→ Intermediate Chain field

Root certificate→ Root CA field

If the chain order is wrong or the server certificate is mistakenly placed in an intermediate or root CA field, the cryptographic signature validation fails. This exact failure mode is documented in VMware certificate replacement workflows.

Option A is incorrect because including an IP address in a CSR does not invalidate chain signatures.

Option B is incorrect because an untrusted CA produces atrustfailure, not asignature mismatch.

Option C is unrelated: accessibility is not required for certificate validation.

In VMware Cloud Foundation 9.0,all host commissioning operationsare performed throughVCF Operations, not through vSphere Client, Cloud Builder, or the VCF Installer. Once VCF is deployed, Cloud Builder is no longer used, and the VCF Installer is for lifecycle and bundle management—not for host workflows. The vSphere Client also cannot commission hosts because host commissioning is a foundational VCF workflow requiring hardware validation, storage type checks, NIC checks, HCL conformance, and version compatibility.

The error message provided:

“Hosts must be unassigned, commissioned with at least one physical NIC and the same storage type… and the ESX version must be compatible…”

is a standard VCF 9.0 validation message shown whenno commissioned hostsmatching the workload domain requirements exist. VMware documentation states that hosts must be commissioned under:

VCF Operations → Fleet Management → Hosts → Commission Host

Here, VCF validates:

Storage type (vSAN ESA, vSAN OSA, NFS, FC, etc.)

Network pool membership (matching the WLD plan)

ESXi version compatibility with the Management Domain baseline

NIC mapping and certifications

Until hosts are commissioned, they cannot appear in the workload domain creation wizard.

Thus, the correct method to commission hosts isD. Using VCF Operations.
