A city wants three control-plane nodes reachable through a stable VIP for API high availability. What kubeadm HA building block is required?
Select an answer to reveal the explanation.
Short Explanation
HA for the API is like giving City Hall one published phone number that rings a pool of operators—not three sticky notes with different digits. Put a VIP or DNS name in controlPlaneEndpoint, run multiple control-plane nodes, and let the load balancer spread the calls. Workers should dial that stable address forever.
Full Explanation
kubeadm HA designs set controlPlaneEndpoint to a load balancer or DNS name fronting multiple control-plane instances. Clients and workers use that stable endpoint so losing one control-plane host does not require reconfiguration. Multiple control-plane nodes without a shared endpoint leave clients pinned to a single SPOF IP.
