Your organization is deploying a large-scale Kubernetes cluster with hundreds of nodes. The operations team wants to minimize the impact of etcd performance on the control plane and ensure that etcd can be scaled independently. Which etcd topology should you choose?

Stacked etcd on dedicated nodes, with control plane components on separate nodes.

External etcd on the control plane nodes, with etcd and control plane components co-located.

External etcd on dedicated nodes, with etcd and control plane components on separate hardware.

Stacked etcd on the control plane nodes, with etcd and control plane components co-located.

What is the key difference between a stacked etcd topology and an external etcd topology?

In stacked, etcd uses TLS; in external, it does not

In stacked, etcd is managed by Kubernetes; in external, it is managed by the cloud provider

In stacked, etcd is a single node; in external, it is multi-node

In stacked, etcd runs on the same nodes as the control plane; in external, etcd runs on separate nodes

When provisioning a new control plane node, which file contains the kubeconfig used by the kube-scheduler to communicate with the API server?

/etc/kubernetes/controller-manager.conf

Implement and Configure a Highly-Available Control Plane CKA Practice Questions (Page 4)

Part of the Cluster Architecture, Installation and Configuration domain, which accounts for 25% of the CKA exam. Linux Foundation does not publish an official question count, but from its 120-minute exam (~50–80 total, ~13–20 in this domain), expect 2–3 from this objective — we provide 26 practice questions to prepare you well beyond it.
