- A
Run 'kubectl debug -it pod-name --image=busybox --target=container-name' to start an ephemeral debug container
Ephemeral containers allow debugging without modifying the original pod.
- B
Run 'kubectl exec -it pod-name -- /bin/bash' to interact with the container
This opens a shell inside the container, allowing you to run commands.
- C
Run 'kubectl logs pod-name --tail=50' to view recent log output
Logs can show errors or messages from the application.
- D
Run 'kubectl attach pod-name' to attach to the container's main process
Why wrong: 'kubectl attach' attaches to the primary process, but it's rarely used for debugging and requires the process to support stdin.
- E
Run 'kubectl get pod pod-name -o yaml' to examine the pod's current YAML definition
Why wrong: This shows the pod's configuration, but not runtime state or behavior.
CKAD Application Observability and Maintenance Practice Question
This CKAD practice question tests your understanding of application observability and maintenance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 THREE of the following are valid ways to debug a pod that is not responding? (Select three.)
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
Run 'kubectl debug -it pod-name --image=busybox --target=container-name' to start an ephemeral debug container
Multiple methods exist: exec for interactive shell, logs for output, debug for ephemeral containers. Option B is not a valid command; Option D is for configuration files, not runtime debugging.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
This shows the pod's configuration, but not runtime state or behavior.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 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.
