Kubernetes and Cloud Native Associate (KCNA) — Question 57

What is a probe within Kubernetes?

Answer options

• A. A monitoring mechanism of the Kubernetes API.
• B. A pre-operational scope issued by the kubectl agent.
• C. A diagnostic performed periodically by the kubelet on a container.
• D. A logging mechanism of the Kubernetes API.

Correct answer: C

Explanation

The correct answer is C because probes are used by the kubelet to periodically check the health and status of containers. Options A, B, and D do not accurately describe the function of probes, as they relate to monitoring, pre-operation, and logging rather than diagnostic checks.
