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.
-
Reference Architecture for a VKS Deployment, NSX, VDS and Zones (VCAP-VKS Exam Series, Part 4)
Objective 1.3 asks you to pick a reference architecture, not describe one. Here are the four published vSphere Zone models, the four Supervisor networking paths, and the single decision you can never take back.
-
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.
-
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.
-
VCAP-VKS Exam Blueprint, Scoring and a Study Plan (VCAP-VKS Exam Series, Part 1)
A working map of the 3V0-24.25 blueprint: 60 items, 135 minutes, 33 published objectives, and the one section that carries 42 percent of them. Plus a six week study plan built around a lab rather than a reading list.

How to Become a Broadcom Knight: A Step-by-Step Guide
A plain-language, step-by-step guide to earning Broadcoms highest partner recognition – what the Knights program is, who qualifies, the certifications you need, and how to get nominated.
-
Decommissioning TKGI and Ops Manager, and What Comes Next (TKGI to OpenShift Series, Part 26)
A ten step teardown runbook for retiring a TKGI estate after the OpenShift cutover, covering cluster deletion, the TKGI tile, Ops Manager, BOSH, and the NSX-T and vSphere objects that survive every documented step.
-
OpenShift Observability, Backup and Disaster Recovery (TKGI to OpenShift Series, Part 25)
A runbook for giving a freshly migrated OpenShift cluster real metric retention, restorable etcd snapshots and scheduled OADP application backups. Three recovery domains, three tools, and measured restore times for each.
-
Day-2 on OpenShift, Operators, Upgrades and Scaling vs BOSH (TKGI to OpenShift Series, Part 24)
Production traffic is on OpenShift, so now you own a platform that updates itself. Here is the runbook we use for a minor update, Operator channels, MachineSet scaling and health checks, with the timings and the two failures that cost us a window.
-
Production Cutover, Traffic Shift, Validation and Rollback (TKGI to OpenShift Series, Part 23)
Moving live production traffic off TKGI onto OpenShift without a visible outage, using weighted Routes as the only lever on the night. Includes a five step traffic ladder, real preflight commands, and a cutover I reversed at 03:40.
-
Pilot Migration, One Non-Prod Cluster End to End (TKGI to OpenShift Series, Part 22)
A pilot that passes proves nothing unless the app team runs it. Here is how I moved one non production TKGI cluster onto OpenShift 4 end to end, with the exit criteria scorecard, the real timings and the rollback.
