This CKAD practice question tests your understanding of application observability and maintenance. 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.
Which command streams logs from a pod in real-time?
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 logs --stream pod-name
Why wrong: There is no --stream flag; the correct flag is -f or --follow.
kubectl logs -f pod-name
The -f flag follows log output in real-time.
kubectl logs --previous pod-name
Why wrong: This shows logs from the previous instance of the container, not live streaming.
kubectl logs pod-name
Why wrong: This prints the current logs but does not follow new output.
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 -f pod-name
Option B is correct because `kubectl logs -f` (the `-f` flag stands for 'follow') streams log output from a pod in real-time, similar to `tail -f` on a file. This is the standard Kubernetes command for continuous log monitoring, allowing you to see new log lines as they are written by the container.
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 logs --stream pod-name
Why it's wrong here
There is no --stream flag; the correct flag is -f or --follow.
kubectl logs -f pod-name
Why this is correct
The -f flag follows log output in real-time.
Clue confirmation
The clue word "which command" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
kubectl logs --previous pod-name
Why it's wrong here
This shows logs from the previous instance of the container, not live streaming.
kubectl logs pod-name
Why it's wrong here
This prints the current logs but does not follow new output.
Common exam traps
CNCF often tests the `-f` flag against the non-existent `--stream` flag, exploiting the candidate's assumption that a verbose flag name exists when the actual flag is a short form.
Trap categories for this question
Command / output trap
This shows logs from the previous instance of the container, not live streaming.
Detailed technical explanation
Under the hood, `kubectl logs -f` uses the Kubernetes API's `PodLogOptions` with `Follow: true`, which opens a long-lived HTTP connection to the kubelet on the node hosting the pod. The kubelet then streams the container's stdout/stderr logs via the container runtime (e.g., containerd or CRI-O), and the connection remains open until terminated by the user or a timeout. In a real-world scenario, you might combine `-f` with `--tail=50` to start streaming from the last 50 lines, avoiding an initial flood of old logs.
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 CKAD 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.
