CKA CrashLoopBackOff diagnosis Practice Question
This CKA practice question tests your understanding of troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 Deployment's pods are failing with 'CrashLoopBackOff'. The container exits with code 1. Which two approaches will help identify the issue? (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
✓
kubectl logs <pod>
A is correct because `kubectl logs <pod>` retrieves the container's stdout/stderr output, which often contains the error message or stack trace that caused exit code 1. This is the first step in debugging a CrashLoopBackOff, as it reveals what the application printed before terminating.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

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
The trap here is that candidates may think `kubectl get pods -o wide` provides troubleshooting details, but it only adds IP and node info, not logs or events, while `kubectl edit` is a remediation step, not a diagnostic one.

Detailed technical explanation
How to think about this question
Exit code 1 typically indicates a generic application error, such as a missing configuration file, a failed dependency, or an unhandled exception. `kubectl logs` reads from the container's log file stored on the node's filesystem (under /var/log/pods/), while `kubectl describe pod` shows the last termination state and exit code, plus recent events from the kubelet that may indicate resource limits or liveness probe failures. In a real-world scenario, combining logs with describe events often pinpoints whether the issue is a misconfigured environment variable or a missing secret.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
