CKA study material · question 897 of 1000

Kubernetes provides no cluster-level logging of its own. Which two of the following are documented approaches? Choose two.

  1. A node-level logging agent on every node
  2. The API server writing Pod logs to etcd
  3. A sidecar container in each application Pod
  4. The kubelet forwarding logs to the control plane
Show the answer

Answer: A. A node-level logging agent on every node
C. A sidecar container in each application Pod

The three documented options are a node-level agent, a logging sidecar, or the application pushing directly to a backend. Neither etcd nor the kubelet aggregates logs.
