This EX200 practice question tests your understanding of manage containers. 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.
An administrator needs to list all container images stored locally, including intermediate layers. Which command should be used?
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.
podman images -q
Why wrong: This only shows image IDs, not all layers.
podman images --all
Why wrong: This flag is not valid; podman images does not have --all.
podman images --no-trunc
Why wrong: This shows full output but does not reveal intermediate layers by default.
podman images -a
Correct. The -a flag shows all images including intermediate layers.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
podman images -a
Option D (`podman images -a`) is correct because the `-a` (or `--all`) flag instructs Podman to list all images in the local storage, including intermediate layers that are not tagged and are used as building blocks for other images. Without this flag, only top-level (tagged) images are shown, which would omit the intermediate layers the administrator needs to see.
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.
podman images -q
Why it's wrong here
This only shows image IDs, not all layers.
podman images --all
Why it's wrong here
This flag is not valid; podman images does not have --all.
podman images --no-trunc
Why it's wrong here
This shows full output but does not reveal intermediate layers by default.
podman images -a
Why this is correct
Correct. The -a flag shows all images including intermediate layers.
Clue confirmation
The clue word "which command" in the question point toward this answer.

Common exam traps
The trap here is that candidates confuse `-a` (all images including intermediates) with `-q` (quiet mode) or `--no-trunc` (full output), mistakenly thinking those flags also reveal hidden layers.
Trap categories for this question
Command / output trap
This only shows image IDs, not all layers.
Detailed technical explanation
Podman stores images in a layered filesystem (using overlayfs or similar), where each layer corresponds to a Dockerfile instruction. Intermediate layers are untagged and have no repository reference, so they are hidden by default to reduce clutter. The `-a` flag queries the local image store (usually under `/var/lib/containers/storage`) and returns all layers, which is essential for tasks like cleaning up dangling images (`podman image prune`) or debugging build cache issues.
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 EX200 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.
