One command to provision. Browser-based terminal. Timed mock exams with per-question setup and automated validation. --- Why K16S Most Kubernetes practice labs run kind (Kubernetes-in-Docker) or lightweight k3s clusters. Both have real limitations for exam prep: - kind runs all nodes as containers inside a single Docker daemon, no real node isolation, no systemctl , no kubelet config files, no crictl - k3s omits many kubeadm-specific workflows entirely (cluster init, etcd backup, certificate management, static pod manifests) K16S uses a real kubeadm-provisioned cluster with Incus LXC containers as worker nodes. Each worker is a full Linux system with its own init, systemd, containerd, and kubelet. This matches what the actual CKA/CKS exam environment runs.
