- A
Delete the pod immediately
Why wrong: Deletion destroys evidence.
- B
Take a memory dump of the container
Correct: Captures in-memory data.
- C
Run kubectl exec to explore and modify files
Why wrong: Modifying files alters evidence.
- D
Create a forensic snapshot of the container filesystem
Correct: Captures filesystem state.
- E
Capture container logs
Correct: Logs provide activity history.
Question 583 of 997
Preserving Evidence During a Container Security Incident
This CKS practice question tests your understanding of monitoring, logging and runtime security. 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 THREE of the following are effective methods to preserve evidence during a container security incident?
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
✓
Take a memory dump of the container
Option B is correct because taking a memory dump of the container captures volatile data (processes, network connections, encryption keys) that is lost when the container stops. This preserves runtime evidence critical for forensic analysis, as memory artifacts are not persisted to disk and must be collected before the container is terminated.
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
A common trap is confusing incident response containment (which may require isolating the pod via network policies or cordoning the node) with evidence preservation (which requires capturing data before deletion). Immediate pod deletion destroys evidence and should be avoided until forensic data is collected.
Detailed technical explanation
How to think about this question
Memory dumps in containers are typically captured using tools like `cat /proc/.../mem` or `gcore` from the host, or via `kubectl exec` with `dd` if /proc is accessible. The container's filesystem snapshot is often taken using `docker commit` or by creating a tarball of the overlay filesystem from the host (e.g., `/var/lib/docker/overlay2/<id>/diff`). In Kubernetes, container logs are retrieved via `kubectl logs --previous` to capture logs from a terminated container, which is essential for reconstructing the timeline of an incident.
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 practitioner preparing for the CKS 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.
