Kubernetes and Cloud Native Associate (KCNA) — Question 159

Which of the following options include resources cleaned by the Kubernetes garbage collection mechanism?

Answer options

• A. Stale or expired CertificateSigningRequests (CSRs) and old deployments.
• B. Nodes deleted by a cloud controller manager and obsolete logs from the kubelet.
• C. Unused container and container images, and obsolete logs from the kubelet.
• D. Terminated pods, completed jobs, and objects without owner references.

Correct answer: D

Explanation

The correct answer is D, as Kubernetes garbage collection specifically targets terminated pods, completed jobs, and orphaned objects without owner references for cleanup. Options A, B, and C mention resources that are not automatically cleaned up by the garbage collector, such as CertificateSigningRequests and logs.
