ACE Practice Question: A deployment pipeline runs `kubectl logs` to…
This ACE practice question tests your understanding of a deployment pipeline runs `kubectl logs` to…. 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.
A deployment pipeline runs `kubectl logs` to capture output from a crashed Pod's previous container instance. Which flag retrieves logs from the previous (terminated) container instance rather than the current one?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
kubectl describe pod api-pod | grep -A 50 'Last State'
`kubectl describe` shows metadata and events but not the full container logs. Use `kubectl logs --previous` for log content from the terminated container.
B
Distractor review
kubectl logs api-pod --terminated
`--terminated` is not a valid kubectl logs flag. Use `--previous` or `-p` for the previous container instance.
C
Best answer
kubectl logs api-pod --previous
`--previous` (or `-p`) retrieves logs from the last terminated container instance — essential for debugging containers that crash on startup.
D
Distractor review
kubectl logs api-pod --all-containers --since-crash
`--since-crash` is not a valid flag. `--all-containers` shows logs from all containers in the Pod but doesn't target the previous instance.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

FAQ
Questions learners often ask
What does this ACE question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: kubectl logs api-pod --previous — `kubectl logs [POD] --previous` (or `-p`) retrieves logs from the previously terminated container instance in the Pod. Without this flag, `kubectl logs` shows the current container's logs — which may be empty if the container just restarted.
What should I do if I get this ACE question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ACE NAT questions on configuration and troubleshooting.
