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.

In VMware Cloud Foundation, deletion of a workload domain requires that VCF Operations can correctly discover and process the NSX components attached to that domain. The workload domain delete workflow explicitly includes removal of the NSX Manager and NSX Edge components associated with the domain, unless those NSX components are shared.

In earlier and current VCF guidance, VMware state that NSX Edge clusters for a workload domain must be removed using the documented/VCF-aware method (for example, using the NSX Edge removal process referenced in KB 78635, not by deleting objects directly in NSX Manager). If an administrator deletes theNSX Edge cluster directly in NSX Manager, the VCF inventory and orchestration logic still “believes” the Edge cluster exists. When the workload domain delete workflow reaches the stage“Gather input for deletion of NSX component”, it queries NSX / internal state for Edge cluster data. Because the underlying object has been manually removed, the returned structure is null, which results in an internal“Cannot read the array length because "<locall9>" is null”style error.

Using theNSX Edge Cluster Deployment Removal Toolas per documentation keeps VCF and NSX in sync and is thesupportedpath, so option A is not the likely cause. Network pools and shared NSX Manager configurations do not match the specific NSX-component array/null condition described.

InVMware Cloud Foundation (VCF) 9.0, the management of appliance credentials and lifecycle operations is centralized within theVCF Operations Fleet Manager(which subsumes the roles of the legacy SDDC Manager Life Cycle Management).

The Problem:The administrator is unable to log in as root via the console or SSH. This indicates a credential synchronization issue or account lockout, which prevents them from manually enabling SSH via the console (the traditional method).

The Solution (Remediate Password):The "Remediate Password" workflow in VCF Operations allows the administrator to reset and synchronize the root password for VCF components (like the VCF Ops instance itself) directly from the management plane.

By navigating toFleet Management > Passwords(or similar path in VCF 9.0), the administrator can select the affected instance and chooseRemediate.

This process updates the password in the centralized database and on the appliance, restoring the ability to log in.

Once the root access is restored via remediation, the administrator can then proceed to enable SSH (either via the VCF Operations settings UI or the console). Without the correct password (which "Remediate" fixes), SSH cannot be enabled.

Note: Options A and B (Reset/Reboot) are legacy manual steps that do not ensure the VCF inventory database is updated, potentially leading to further "configuration drift" or sync errors. Option C is unnecessary for a credential issue.

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.

The status"Node Not Ready"in the NSX Manager UI (specifically in theConfiguration Statecolumn of the Edge Transport Nodes view) indicates that the NSX Manager has failed to push or validate the necessary configuration to the Edge VM.

Check Uplink Network Configuration (Option C):This is the most common cause for a "Node Not Ready" state during deployment or operation. For an Edge Node to be "Ready" (Success/Up), it must have a validTransport Nodeconfiguration, which includes theUplink Profile,IP Pool(for TEPs), and mapping to theFastpath Interfaces(N-VDS). If the uplink configuration is missing, incorrect, or the management plane cannot communicate with the edge to apply it, the node remains in a "Not Ready" state.

Why not Option A?While an Edge must be in anEdge Clusterto beutilizedby a Tier-0 Gateway, a standalone Edge Node should still report a status of "Success" (Configuration) and "Up" (Node Status) if it is healthy. Adding a "Not Ready" (unhealthy/unconfigured) node to a cluster will not fix the underlying configuration issue.

Why not Option D?Missing CPU reservations typically lead to a"Degraded"status or service crashes (Dataplane down), but "Node Not Ready" is the specific indicator of an incomplete or stalled configuration workflow, usually tied to the transport/uplink setup.

When anNSX Adminaccount becomes locked in NSX Manager, this occurs due to failed login attempts exceeding the lockout threshold for either:

CLI access,

API access, or

UI login, which is tied to API authentication.

Once locked, the only supported method to recover the NSX admin account is tolog in to the NSX Manager console as the root userand manually clear the lockout counters. This is documented in NSX Manager password-recovery procedures and is the standard administrative recovery action.

The root console provides access to:

clear account-lockout admin

or the equivalent reset methods within NSX Manager.

Why the other options are incorrect:

A. SSH into NSX Manager as AdminImpossible — the admin account is locked and cannot be used to SSH.

B. Change password age policy in vCenterNSX Manager accounts arenotgoverned by vCenter password policy.

C. Rotate admin password in SDDC ManagerSDDC Manager rotates NSX passwords when unlocked; it cannot unlock a locked account.

VMware Cloud Foundation 9.0 Operations manages credentials for integrated components such as vCenter Server through its internal password vault. When administrators modify passwordsdirectly on the component—such as manually changing thevCenter rootpassword—VCF Operations is no longer able to authenticate using its stored credentials. As a result, any password rotation or update operation initiated through VCF Operations fails during the validation step.

The error"Failed to authenticate with the guest operating system using the supplied credentials"is a direct symptom of this condition. VCF Operations attempts to log in to vCenter using thepreviously stored credential, which no longer matches the actual root password. Documentation describes this as an "out-of-sync credential state," and the resolution is to performpassword remediationto re-synchronize VCF Operations with the system.

Option A (password complexity) is irrelevant because complexity is validated only after authentication.

Option C (vCenter down) would generate connectivity errors, not authentication errors.

Option D (SSH disabled) does not prevent password rotation because VCF Operations uses VMware Tools guest operations, not SSH, for authentication.

This issue stems from an incorrect role assignment during the user creation process in VMware Cloud Director (VCF Automation).

Organization Administrator Role (Option D): This role grants full control, including visibility of the Administration tab (to manage users, groups, and settings), Data Centers, and Monitor tabs. If the user were an Admin, they would see all tabs.

Organization Auditor Role (Option A): This is a read-only role, but by definition, an Auditor can view anything an Organization Administrator can see (including the Administration settings), just without edit rights. Therefore, an Auditor would still see the Administration tab.

Organization User Role (Option B): This is a consumer-level role designed for deploying and managing vApps. By default, this role does not have access to the Administration tab or high-level organization settings. If the organization is new and has no vApps or VDCs populated yet, a user with this role might see a very restricted view (effectively just a dashboard or "Overview") because they lack the rights to see the administrative configuration menus.

Conclusion: The fact that the "Administration" tab is missing (implied by "only Overview is visible") identifies the user as an Organization User (or a restricted Custom Role) rather than an Administrator or Auditor.

VMware Cloud Foundation (VCF) 9.x usesVMware Identity Broker (VIDB)as the central identity provider for the entire VCF fleet. VIDB synchronizes user and group metadata from the connected enterprise identity source, in this caseActive Directory. When a user is added to an AD groupafterthe group was already synced into VIDB,VIDB does not automatically resync group membership on demandunless a directory synchronization is performed.

In this scenario, the groupVCFA_ProviderAdminswas synchronized five days earlier. When the new userprovideradmin05was later added to the AD group, VIDB—and therefore the VCF Automation Provider Management Portal—does not recognize that new user until amanual directory resynchronizationoccurs fromVCF Operations.

This operation forces VIDB to:

Requery Active Directory

Update group membership information

Repopulate available users for import into VCF Automation

Options B and D are incorrect because they donotinfluence Identity Broker directory synchronization. Option C (disable VCF SSO) would break authentication and is not a valid solution.

To collect detailed per-VM CPU metrics—especiallyCPU Ready (%RDY)—the correct command-line utility on an ESXi host isesxtop. This tool provides real-time, low-level performance data for CPU, memory, disk, and network usage, and is the authoritative method for diagnosing CPU contention issues in VMware environments.

When troubleshootinghigh CPU Ready times, esxtop allows administrators to:

View CPU contention at the VM level

Inspect co-stop, wait, and scheduling delays

Monitor NUMA distribution and pCPU saturation

Capture historical performance snapshots using batch mode

The other options do not provide the necessary VM-level CPU scheduling metrics:

A. vimtop: Only available on vCenter Server Appliance (VCSA), not ESXi; doesnotshow VM CPU ready.

B. esxcli: Used for configuration and health checks; not for real-time CPU metrics.

C. vim-cmd: Used to manage VMs via vSphere API bindings; not a performance monitoring tool.

When troubleshootingBGP peering issueson an NSX Edge Transport Node, VMware documentation directs administrators to examinerouting logs, because BGP failures are often caused by adjacency negotiation errors, authentication mismatches, keepalive/hold timer issues, or route-policy failures.

The NSX Edge CLI command:

get log-file routing follow

streams real-time routing logs, including BGP daemon logs (bfdd, routed, wdog) and provides detailed insight into:

BGP session establishment and teardown

Keepalive and hold timer exchanges

Neighbor state transitions

Route advertisement or rejection

Authentication mismatches

MTU or connectivity issues on TEP / uplinks

This is theonlycommand in the list that exposesdiagnostic-level BGP informationneeded to troubleshoot peering.

Option A (edge-cluster status) shows cluster membership only.

Option B (get logical-routers) shows logical router configuration, not BGP logs.

Option C (edge-cluster history state) is unrelated to routing.

When VMware Cloud Foundation Operations performs actions on vCenter—such as powering on or off a VM—the tasks are initiatedthrough an integration service account, not the identity of the user logged into the VCF Operations UI. VCF Operations connects to vCenter using a configuredcollector or integration credential, typically a service account defined during initial setup.

VCF documentation clarifies that all automated or orchestrated tasks originating from VCF Operations use this trusted account to ensure consistent auditing, RBAC enforcement, and operational isolation from user identities. Therefore, in the vCenter task pane, the “Initiated By” field always reflects theVCF Operations ? vCenter service account, even if the end-user triggered the action indirectly.

Option A is incorrect because the logged-in user does not directly interface with vCenter.

Option C refers to SDDC Manager’s integration account, which is unrelated to VCF Operations workflows.

Option D (administrator@vsphere.local) appears only when vCenter’s built-in admin performs the action.

To successfully configure aMicrosoft Certificate Authority (CA)inVMware Cloud Foundation (VCF) Operations(formerly vRealize/Aria Operations), the service account used for the integration must have specific permissions on the Certificate Template (e.g., the "VMware" template).

Required Permissions:The VCF 9.0 and Aria Operations documentation explicitly states that the service account must be assignedReadandEnrollpermissions on the target Certificate Template.

Read:This permission is critical for the "Discovery" and "Validation" phase. It allows VCF Operations to query the CA, list available templates, and read the template's properties (like Key Usage and Extended Key Usage) to ensure they meet the security requirements (e.g., Server Authentication, Non-Repudiation).

Enroll:This permission allows the account to actually submit a Certificate Signing Request (CSR) via the interface and receive a signed certificate.

The Cause of Failure (Option A):If the user account is configured withonly the "Enroll" permission, it effectivelylacks the "Read" permission. Without "Read", VCF Operations cannot "see" or validate the template during the configuration wizard. The application attempts to fetch the template details, fails (because the template is invisible to it), and throws the error"Certificate authorities update failed."

Why other options are incorrect:

Option D (Read and Enroll):This is thecorrectand recommended configuration. If the user had these permissions, the operation would succeed (assuming other prereqs like Basic Auth are met).

Option C (Autoenroll):TheAutoenrollpermission is designed for Windows Group Policy-based background renewal. It isnot requiredfor the VCF Operations API-based integration, which relies on explicit "Enroll" calls.
