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`.

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.
