VKS Cluster Performance Optimization with Monitoring and Scaling (VCAP-VKS Exam Series, Part 34)
Objective 5.5 is a measurement objective wearing a scaling costume. Here is the metrics pipeline, the four scaling levers, what each one measurably moves on a VCF 9.0 estate, and the request gap that makes all of them lie to you.

Failed VKS Cluster Upgrade Recovery Without Deleting Nodes (VCAP-VKS Exam Series, Part 33)
A stalled VKS cluster upgrade is a live reconciliation loop blocked on a precondition, not a crashed job, and deleting the stuck node destroys your evidence without unblocking anything. Here is how to classify the stall from Cluster API conditions and clear it in the right context.

VKS Registry and Trusted CA Errors in Container Deployment (VCAP-VKS Exam Series, Part 32)
Objective 5.3 as a runbook: separating x509 trust failures from registry authentication failures on a VKS cluster, the double encoded secret the Supervisor expects, and the version window where the fix applies but never reaches containerd.
-
VKS VM Class, Cluster Plan and Content Library Fault Diagnosis (VCAP-VKS Exam Series, Part 31)
Objective 5.2 packs five different fault families into a single line of blueprint text. Here is the five gate sweep I use to tell a VM class binding problem from a cluster plan certificate defect, with the real error strings and the surface that actually fixes each one.
-
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.
