Pearson 3V0-24.25 New Attempt

Configuration Sequence (in order):

Deactivate the service.

Confirm uninstallation.

Delete the service.

Confirm deletion.

Uninstalling a Supervisor Service cleanly follows a “stop/remove/cleanup” pattern to avoid orphaned components and to ensure the Supervisor isn’t still reconciling the service while you remove it. First, youDeactivate the serviceso the Supervisor stops managing and running the Harbor service components. This prevents new service resources from being created while you are attempting to remove them and allows the platform to transition the service into a non-operational state safely.

Next, youConfirm uninstallationto initiate the removal workflow. This step acknowledges that the service’s deployed components (such as pods, controllers, and any associated objects) will be removed from the Supervisor-managed environment. After the uninstall workflow is initiated and the service is no longer active, you proceed toDelete the serviceto remove the Harbor service registration/entry from the Supervisor Services list, ensuring it is no longer available to namespaces or consumers. Finally, youConfirm deletionas the last safeguard, since deletion is typically destructive and removes the service definition from the environment’s available services catalog.

VCF 9.0 design guidance for theSupervisor NSX Load Balancer modelstates that theNSX load balancers run on NSX Edges, and sets explicit sizing requirements at theEdge nodelevel. In the “NSX Load Balancer Design Requirements,” VCF 9.0 requires that theNSX Edge cluster must be deployedbecause “NSX Load Balancers run on NSX Edges.” It further requires that“NSX Edge nodes must be deployed with a minimum of Large form factor”because NSX load balancers havefixed resource allocations on NSX Edge nodes, and the Large form factor is needed to accommodate basic system and workload needs.

This directly ties “deployment size” of the load balancer service capacity to theEdge node form factor(Small/Medium/Large, etc.) rather than the number of pods or the number of clusters. The document also notes that if additional load balancers are required, NSX Edges can bescaled up or out, again reinforcing that sizing is anEdge nodesizing decision.

Answer (Correct Order):

Navigate in VCF Operations to Fleet Management → Tasks, select the instance and review Tasks

Check for errors or failed ClusterConfig objects

SSH into the Supervisor Cluster to review logs / attempt manual cleanup if required

Restart the WCP Service

To determinewhya Supervisor upgrade failed, you start where the platform records the most actionable failure context: themanagement-plane task history. The Fleet/Task view surfaces the upgrade workflow steps, timestamps, and the specific operation that failed, which gives you the fastest pointer to the failing phase (precheck, image staging, reconciliation, add-on updates, etc.). Next, you validate the Kubernetes-side reconciliation state by checking forfailed ClusterConfigobjects, because Supervisor enablement/upgrade actions commonly drive configuration via controller reconciliation; a failed ClusterConfig often contains the clearest “reason” and “message” fields that explain what blocked progress (validation errors, dependency issues, unreachable endpoints, incompatible components).

If the management-plane/task view and ClusterConfig status still don’t isolate the root cause, the next escalation is toSSH into the Supervisorto inspect component logs/events and identify low-level failures that may not bubble up cleanly (for example, admission failures, controller crashes, or connectivity/auth issues). Finally,restarting WCPis a remediation step that can clear stuck states, but it’s placed last because it can alter evidence and should not be your first action when you’re still trying to identify the original failure cause.

Kubernetes Role-Based Access Control (RBAC) is implemented through theRBAC API group(rbac.authorization.k8s.io) and defines the core authorization primitives used to grant permissions to users, groups, and service accounts. The cluster-scoped objects declared by the RBAC API areClusterRoleandClusterRoleBinding. AClusterRoledefines a set of permissions (verbs such as get/list/watch/create/update/delete) over resources at thecluster scope(including cluster-wide resources and optionally namespaced resources across namespaces). AClusterRoleBindingthenbindsthat ClusterRole to a subject (user/group/serviceaccount), making those permissions effective cluster-wide.

This differs from namespace-scoped RBAC objects (RoleandRoleBinding) which apply only within a single namespace. The other options are incorrect becauseClusterObject/ClusterNodeare not RBAC API objects,ValidatingAdmissionPolicybelongs to the admission control API surface (policy enforcement),ResourceQuotais a namespace resource governance object, andContainer/Deploymentare workload/runtime concepts defined in the core/apps APIs rather than authorization primitives.
