CKA Node NotReady kubelet checks Practice Question
This CKA practice question tests your understanding of troubleshooting. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A worker node is marked NotReady. Which two checks are most relevant to diagnose the node's kubelet health? (Choose two.)
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
✓
systemctl status kubelet
A is correct because `systemctl status kubelet` directly queries the systemd service manager to report whether the kubelet process is running, its current state (active/inactive/failed), and recent log entries. Since the kubelet is the primary node agent responsible for registering the node and reporting status to the control plane, checking its service status is the most immediate step when a node is NotReady.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CKA exam frequently reuses these exact scenarios with slightly different constraints.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CNCF often tests the misconception that `kubectl get nodes` is a diagnostic tool for node-level issues, when in fact it only reflects the symptom, not the cause; candidates must remember that local service inspection (systemctl/journalctl) is required for kubelet troubleshooting.

Detailed technical explanation
How to think about this question
The kubelet uses a local HTTP endpoint (typically on port 10250) for health checks and reports node status via periodic NodeStatus updates to the API server. When the kubelet fails, the node controller in the kube-controller-manager sets the node to NotReady after a default `node-monitor-grace-period` of 40 seconds. Using `journalctl -u kubelet -n 50` captures the last 50 lines of the kubelet's systemd journal, which often contain specific error codes (e.g., `PLEG is not healthy`, `failed to get CNI config`, or `out of disk pressure`) that pinpoint the root cause.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CKA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
