170 Hands-On Lab Tasks for the VCAP-VKS Exam 3V0-24.25 (VCAP-VKS Exam Series, Part 35)
Thirty-four parts of this series went through the 3V0-24.25 blueprint one objective at a time. This part is the other half: a workbook of 170 hands-on tasks in build order, from enabling a Supervisor to recovering a stalled upgrade. Each task carries the exam objective it covers, and the whole set is downloadable as a…

How I am turning my one laptop into a full AI and Kubernetes lab, layer by layer
My blueprint for rebuilding my AI applications (DrJhaGPT Pro, the Neevalay bots) as a production-style platform on one 20 GB laptop: 36 layers across cluster, delivery, security, observability, AI serving, backup and cost. For every layer, what I run today, the free open-source pick for the lab, and a drop-down of the enterprise products (VKS,…

I run a 70B model for free and own no GPU. So where does the enterprise AI stack come in?
One AI application followed end to end from a solution architect’s chair: how a RAG tool runs without a GPU, what VRAM and quantization mean, what a GPU would and would not change, why token limits disappear, where Kubernetes fits, and the sizing worksheet, BOM and three-year cost an architect has to produce. Every term…

VKS Cluster YAML Edits That Change a Live Deployment (VCAP-VKS Exam Series, Part 29)
Objective 4.14 in practice: which fields in a VKS cluster manifest you may edit, which edits roll every node, which the admission webhook refuses, and how to force a redeployment when an accepted edit never reaches the nodes.
-
VKS Cluster Autoscaler Install, Configuration and Upgrade (VCAP-VKS Exam Series, Part 22)
Objective 4.7 asks you to create, configure and upgrade autoscalers on VKS. This Part builds an autoscaled cluster from annotations, installs the package, measures six real scale up events, and walks the pause and repin sequence that an autoscaled upgrade demands.
-
VKS Cluster Rolling Updates and Configuration Changes (VCAP-VKS Exam Series, Part 21)
A rolling update on a VKS cluster behaves differently depending on whether you changed the Kubernetes version or a configuration variable. Part 21 runs both against the reference estate, shows the output that lies to you, and covers objective 4.6.
-
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.
-
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.
-
Kubernetes Architecture, Networking, Storage, Service Mesh and Helm (VCAP-VKS Exam Series, Part 3)
Objective 1.2 does not test Kubernetes trivia. It tests whether you can look at a VKS cluster and name the vSphere object that created what you are seeing. Four kubectl commands, two real failures, and the inheritance map that makes the rest of the blueprint readable.

Migrating a Stateless Application End to End (TKGI to OpenShift Series, Part 18)
Moving your first stateless namespace off TKGI is less about Velero than about what OpenShift admission does to the pods when they land. Here is the whole loop, including a restore that reported success while nothing started.
-
Network Policy and Microsegmentation, NSX-T DFW to OVN-Kubernetes (TKGI to OpenShift Series, Part 16)
Your NSX-T distributed firewall holds far more rules than kubectl will ever show you. Here is the DFW to OVN-Kubernetes mapping, a namespace baseline that does not break DNS, and where AdminNetworkPolicy actually belongs.
