VKS Cluster Provisioning, Monitoring and Scaling Commands (VCAP-VKS Exam Series, Part 20)
Objective 4.5 asks you to provision, delete, monitor and scale VKS clusters with kubectl and the VCF CLI. Here is the full lifecycle on a VCF 9.0 estate, with the operations the Supervisor refuses and the one the VCF CLI cannot do at all.

vSphere Pod and VM Service Workload Deployment on a Supervisor (VCAP-VKS Exam Series, Part 18)
Objective 4.3 as one lab: a vSphere Pod and a VM Service virtual machine dropped into the same vSphere Namespace on VCF 9.0, with the real errors each model throws and the Supervisor setting sitting behind them.
-
vSphere Namespaces and Zones, Configuration and Day Two Management (VCAP-VKS Exam Series, Part 17)
Objective 4.2 asks you to configure and manage vSphere Namespaces and Zones. Here is the runbook I use on a three zone VCF 9.0 Supervisor, the fields that lock at creation, and the CPU limit that quietly wedged an autoscaler for 41 minutes.
-
Istio Service Mesh Design for VKS Clusters (VCAP-VKS Exam Series, Part 15)
Objective 3.6 asks you to create an implementation of service mesh, not to name one. Here is how Istio actually lands on a VKS cluster, what sidecar and ambient mode cost in CPU and addresses, and the CNI choice that stops the install dead.
-
Supervisor Cluster Enablement Process on VCF 9 (VCAP-VKS Exam Series, Part 14)
Objective 3.4 is about the process, not the wizard. Five management addresses instead of three, the decisions that lock at activation, and the enablement failures that cost a change window.
-
VKS CNI, NSX Networking Objects and TLS Trust for Secure Clusters (VCAP-VKS Exam Series, Part 10)
Objective 2.5, printed a second time, covers CNIs, NSX networking objects and TLS certificates. Here is the Supervisor level CNI switch, the AntreaConfig override, and the double base64 certificate trap that wedges a VKS cluster in Provisioning.
-
VKS Content Libraries and Kubernetes Releases, Subscribed, Local and Air-Gapped (VCAP-VKS Exam Series, Part 9)
A subscribed library, a local library for the air gapped case, and the VKr naming rule that decides whether kubectl get kr shows anything at all. Objective 2.5 for 3V0-24.25, run against a VCF 9.0 Supervisor.
-
VKS Identity and Access with External Providers and Admin Credentials (VCAP-VKS Exam Series, Part 8)
Objective 2.4 is one registration screen and two authorisation surfaces that look like one. Full lab, the Pinniped path, the empty groups claim that costs candidates ninety minutes, and the break glass kubeconfig secret.
-
Supervisor Storage Policies and Persistent Volume Integration Across Zones (VCAP-VKS Exam Series, Part 7)
Objective 2.3 hinges on one thing candidates skip: every storage policy you attach to a vSphere Namespace produces two storage classes, and picking the wrong one wedges every claim on a three zone namespace. Here is the lab, the failure and the exam angle.
-
Supervisor Networking with VDS, NSX Segments or VPCs and Load Balancing (VCAP-VKS Exam Series, Part 6)
Objective 2.2 is not a load balancer comparison. Your workload network picks the shortlist, and on NSX VPC the shortlist has one name on it. Mapping table, discovery commands and the rebuild that taught me to ask the security question first.
-
Supervisor Capabilities, Services and Architecture Topologies (VCAP-VKS Exam Series, Part 5)
Objective 2.1 asks you to configure Supervisor capabilities, services and topologies. Here is which activation choice is permanent, which you can change on a Tuesday afternoon, and what a control plane resize actually costs in wall clock.
-
VMs and Containers, Choosing the Right Compute Model (VCAP-VKS Exam Series, Part 2)
Objective 1.1 asks you to pick a compute model, not define a container. Here is how vSphere Pods, VM Service virtual machines and VKS clusters actually differ on a VCF 9.0 Supervisor, with a selection matrix, measured provisioning times and the trap that catches vSphere admins.
