Quick Answer
The answer is the `docker history` command. This is the correct tool for forensic analysis of a container because it reveals the complete layer-by-layer build sequence of a Docker image, showing every command executed during construction, including those from the Dockerfile and any intermediate instructions. On the Computer Hacking Forensic Investigator CHFI exam, this command tests your ability to reconstruct how a potentially malicious container was assembled, as investigators can trace back through layers to identify suspicious base images, altered files, or injected scripts. A common trap is confusing `docker history` with `docker logs`—remember that `history` shows the image’s build commands, not the runtime container logs. For a memory tip, think “History reveals the recipe, not the meal.”
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.
In Docker forensics, which command is used to view the command history of a container, including how it was built?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
docker diff
Why wrong: docker diff shows changes to filesystem of a container, not build history.
docker history
This command displays the history of an image, including build commands and layer information.
docker logs
Why wrong: docker logs shows container output, not build history.
docker inspect
Why wrong: docker inspect provides metadata but not the build history.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
docker history
The `docker history` command displays the history of a Docker image, showing each layer and the command that created it. This includes the build commands from the Dockerfile, allowing an investigator to see how the container was constructed and what instructions were executed during the build process.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
docker diff
Why it's wrong here
docker diff shows changes to filesystem of a container, not build history.
docker history
Why this is correct
This command displays the history of an image, including build commands and layer information.
Clue confirmation
The clue word "which command" in the question point toward this answer.

docker logs
Why it's wrong here
docker logs shows container output, not build history.
docker inspect
Why it's wrong here
docker inspect provides metadata but not the build history.
Common exam traps
EC-Council often tests the distinction between commands that operate on running containers (like `docker logs` and `docker diff`) versus those that inspect image metadata (like `docker history`), leading candidates to confuse runtime activity with build-time history.
Trap categories for this question
Command / output trap
docker diff shows changes to filesystem of a container, not build history.
Detailed technical explanation
Each layer in a Docker image corresponds to an instruction in the Dockerfile (e.g., RUN, COPY, ADD), and `docker history` reveals these layers with their creation timestamps and sizes. In forensic investigations, this command can help trace the exact commands executed during the build, including potentially malicious or misconfigured instructions, even if the original Dockerfile is lost. The output includes truncated command strings, so for full details, `docker image history --no-trunc <image>` should be used.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
