The answer is Docker daemon logs, host audit logs, and container image layers. These three artifacts are critical because a container escape typically involves exploiting kernel vulnerabilities or misconfigured capabilities, leaving traces in the daemon’s activity log, the host’s audit trail of system calls, and the container’s filesystem layers where malicious modifications or escape tools may be hidden. On the Computer Hacking Forensic Investigator CHFI exam, this question tests your ability to prioritize forensic sources that bridge the container and host environments—a common trap is focusing only on container-level logs while ignoring host audit records. Remember that the daemon logs capture container lifecycle events, host audit logs reveal abnormal syscalls or privilege escalations, and image layers preserve the original state for comparison against the running container. A useful mnemonic is “D-H-I” for Daemon, Host, and Image—the three pillars of container escape forensics.
CHFI Application, Email and Cloud Forensics Practice Question
This CHFI practice question tests your understanding of application, email and cloud forensics. 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 security analyst is investigating a potential container escape from a Docker container. Which THREE artifacts should the analyst collect to analyze the incident? (Select THREE.)
Host logs may show unusual system calls or access from the container.

✗
Network traffic captures from the host's physical NIC
Why it's wrong here
While useful, network captures are not specific to container escape; host logs are more direct.
✓
Container image layers from the registry
Why this is correct
Image layers help identify if the container was built with malicious content.

✗
Container's memory dump
Why it's wrong here
Memory dumps are useful but not as critical as logs for initial analysis.
✓
Docker daemon logs (e.g., journalctl -u docker)
Why this is correct
Daemon logs record container lifecycle events and errors.

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.
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 CHFI 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.
