A kubeadm binary at v1.35 is used to build a new cluster. Which control plane versions may it deploy?

Answer: B. v1.35 or v1.34

kubeadm can deploy Kubernetes components at its own version or one minor version older, which is a tighter allowance than the three minor versions it permits for the kubelet.
