Diagnosing Supervisor and VKS Provisioning and Namespace Errors (VCAP-VKS Exam Series, Part 30)
Objective 5.1 as a runbook: a fixed reading order for Supervisor and VKS provisioning, connectivity and namespace failures, with the real error lines, the controller namespace that moved on VCF 9.0, and the checks that prove each layer.
-
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 Backup and Restore with Velero and External Object Storage (VCAP-VKS Exam Series, Part 28)
Objective 4.13 asks you to protect a VKS workload with Velero and an S3 bucket. This Part installs the Velero package from the VKS standard repository, moves a 5 Gi claim to MinIO with CSI snapshot data movement, and restores it into an emptied namespace.
-
VKS Workload Deployment Models, Ingress Controllers and Registries (VCAP-VKS Exam Series, Part 27)
Objective 4.12 asks you to build workload deployment models across pods, VMs, ingress controllers and private registries on a VKS cluster. Here is the runbook, the Avi VIP arithmetic that decides the answer, and why the official Contour tutorial fails on a current cluster.
-
VKS Storage Strategies with Dynamic and Static Persistent Volumes (VCAP-VKS Exam Series, Part 26)
Objective 4.11 in a runnable lab: build a dynamic claim, adopt a retained volume statically through a Supervisor PVC handle, and expand a live PostgreSQL volume without losing the pod. Includes the failure lookup and the volumeHandle trap that catches vSphere CSI veterans.
-
Supervisor Update and Kubernetes Version Upgrade Paths (VCAP-VKS Exam Series, Part 25)
Objective 4.10 as a runbook: legal version paths, the Supervisor Management update flow, and why four control plane VMs mid run is healthy rather than broken. Plus the host evacuation phase that quietly eats your maintenance window.
-
VKS Cluster Volume Snapshots, Creation, Restore and Deletion (VCAP-VKS Exam Series, Part 24)
Objective 4.9 hands on. Install the two webhook packages a VKS cluster needs before snapshots exist at all, take a CSI snapshot of a PostgreSQL claim, restore it into a new PVC, and learn why a snapshot is not a rollback.
-
VKS Package Repositories, Registry Secrets and Private Registries (VCAP-VKS Exam Series, Part 23)
Objective 4.8 hinges on knowing which of four separate authentication and trust paths a failed image pull belongs to. This Part installs the standard package repository, places registry secrets where kapp controller can actually read them, and relocates the whole repository into an air-gapped Harbor.
-
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.
-
Harbor Supervisor Service and external-dns Add-on Lifecycle (VCAP-VKS Exam Series, Part 19)
Objective 4.4 is a lifecycle objective, not an install objective. Here is the Harbor Supervisor Service procedure end to end on VCF 9.0, the external-dns package that does not install the same way, and the deactivate then uninstall then delete order that vCenter enforces.
