XK0-006 Practice Question: A sysadmin runs the command and sees the exhibit…

Exhibit

Refer to the exhibit.

$ kubectl get pods
NAME                        READY   STATUS    RESTARTS   AGE
webapp-6b9f5b7c8d-2x7ht    1/1     Running   0          10m
webapp-6b9f5b7c8d-3y8iu    1/1     Running   0          10m
db-7d4f6c8e9f-1a2b3        0/1     CrashLoopBackOff  5   15m

A sysadmin runs the command and sees the exhibit output. What is the most likely cause of the db pod's status?

⚠ Common exam trap

Test-takers frequently confuse a high restart count with a resource exhaustion issue (OOM or CPU), but the key differentiator is the specific exit code and status message shown in `kubectl describe pod` or `kubectl logs`.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The application inside the container is repeatedly crashing.

The pod's status shows a high restart count (e.g., 5+ restarts) in the output of `kubectl get pods`, which is the classic indicator of a CrashLoopBackOff state. This occurs when the container's entrypoint process exits repeatedly, causing the container to crash and be restarted by the kubelet, until the back-off delay increases. The most likely cause is that the application inside the container is repeatedly crashing, not a resource or node issue.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The container is out of memory.

    Why it's wrong here

    An out-of-memory condition would result in OOMKilled status, not CrashLoopBackOff.

  • The node running the pod is unreachable.

    Why it's wrong here

    Node unreachable would show NodeLost or Unknown status.

  • The pod does not have enough CPU resources.

    Why it's wrong here

    CPU issues typically cause performance degradation, not a crash loop.

  • The application inside the container is repeatedly crashing.

    Why this is correct

    CrashLoopBackOff means the container exits with an error and is being restarted repeatedly.
