One city control-plane node is NotReady, yet etcd still has quorum on remaining peers and clients reach the API through the load-balanced VIP. How should this partial failure be interpreted?
Select an answer to reveal the explanation.
Short Explanation
HA is like three cashiers and one shared queue number board (the VIP). One cashier's lane closes, but shoppers still check out if the others and the board stay up—fix that one node.
Full Explanation
Highly available control planes tolerate partial member loss when etcd retains quorum and apiserver instances behind a VIP or load balancer continue serving. A single NotReady control-plane node does not inherently mean total API loss, does not imply etcd has zero peers, and does not mass-delete PVCs. Operators should confirm quorum and VIP health while recovering the failed member.
