This CKA practice question tests your understanding of workloads and scheduling. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
You create a Job named 'pi-job' that runs a single pod to compute pi to 2000 decimal places. After creation, the pod runs and completes successfully. Which command would you use to view the pod's logs after completion?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
kubectl describe job/pi-job
Why wrong: This shows job metadata and status, but not the standard output logs.
kubectl exec job/pi-job -- cat /var/log/pi.log
Why wrong: You cannot exec into a completed pod. Also, the log may not be written to a file.
kubectl log job/pi-job
Why wrong: The correct command is 'kubectl logs', not 'kubectl log'.
kubectl logs job/pi-job
You can view logs of a completed pod using 'kubectl logs' with the job name.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
kubectl logs job/pi-job
Option D is correct because `kubectl logs` is the standard command to retrieve logs from a pod, and it can reference a Job directly by using the syntax `kubectl logs job/<job-name>`. This retrieves the logs from the pod that was created by the Job after it has completed, without needing to know the pod's name.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
kubectl describe job/pi-job
Why it's wrong here
This shows job metadata and status, but not the standard output logs.
kubectl exec job/pi-job -- cat /var/log/pi.log
Why it's wrong here
You cannot exec into a completed pod. Also, the log may not be written to a file.
kubectl log job/pi-job
Why it's wrong here
The correct command is 'kubectl logs', not 'kubectl log'.
kubectl logs job/pi-job
Why this is correct
You can view logs of a completed pod using 'kubectl logs' with the job name.
Clue confirmation
The clue word "which command" in the question point toward this answer.

Common exam traps
The trap here is that candidates confuse `kubectl logs` with `kubectl exec` or `kubectl describe`, or they miss the correct syntax `kubectl logs job/<name>` versus the invalid `kubectl log`.
Trap categories for this question
Command / output trap
This shows job metadata and status, but not the standard output logs.
Detailed technical explanation
Under the hood, `kubectl logs` retrieves the container's stdout/stderr from the kubelet via the API server, which stores logs in a ring buffer on the node. For Jobs, the pod's logs persist even after the pod terminates, as long as the pod's metadata is still in the cluster (e.g., not garbage-collected). In real-world scenarios, you might need to use `--tail` or `--since` to filter logs from long-running batch jobs.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
