High-Availability — Certified Kubernetes Administrator (CKA) Practice Questions

High availability in Kubernetes refers to configuring multiple replicas of control plane components so the cluster can tolerate individual node failures without downtime. The CKA exam expects candidates to understand stacked etcd and external etcd topologies, how load balancers front the API server in HA setups, and how etcd quorum requirements affect the minimum number of control plane nodes. Backing up and restoring etcd is a closely related skill that frequently appears on the exam.
