EX294 Practice Question: Create content collections and execution environments
This EX294 practice question tests your understanding of create content collections and execution environments. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Exhibit
Error: Unable to find a matching container image for execution environment 'ee-30'.
Check that the execution environment is defined in the local container registry.
Refer to the exhibit. A user runs ansible-runner with --container-image localhost/ee-30:latest and receives the error shown. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Error: Unable to find a matching container image for execution environment 'ee-30'.
Check that the execution environment is defined in the local container registry.
A
The container image tag is incorrect.
Why wrong: While possible, the error specifically mentions the image is not found in the local registry, not a tag mismatch.
B
The ansible-runner process does not have network access.
Why wrong: Network access is not required to access a local registry.
C
The execution environment is not listed in the project's execution-environment.yml.
Why wrong: execution-environment.yml is used by ansible-navigator, not ansible-runner.
D
The container image has not been pulled or built locally.
The error says 'defined in the local container registry', meaning the image is missing locally.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The container image has not been pulled or built locally.
The error indicates that the container image `localhost/ee-30:latest` is not available locally. The `--container-image` flag tells ansible-runner to use a specific execution environment image, but if that image has not been pulled from a registry or built locally, the container runtime (e.g., Podman or Docker) cannot find it. Option D is correct because the image must exist in the local container storage before ansible-runner can launch it.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
The container image tag is incorrect.
Why it's wrong here

✓
The container image has not been pulled or built locally.
Why this is correct
The error says 'defined in the local container registry', meaning the image is missing locally.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the distinction between local image availability and network access, leading candidates to incorrectly assume that ansible-runner automatically pulls missing images when it does not by default.
Detailed technical explanation
How to think about this question
When ansible-runner starts a containerized execution environment, it uses the container runtime (Podman by default on RHEL 9) to check local storage for the image. If the image is not present, the runtime returns an error like 'image not known' or 'unable to find image'. The image must be pulled manually via `podman pull` or `docker pull` before running ansible-runner, or built locally with `ansible-builder`. In real-world scenarios, this often happens when a user copies an ansible-runner command from documentation but forgets to pre-stage the execution environment image.
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 EX294 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.

What is the correct answer to this question?
The correct answer is: The container image has not been pulled or built locally. — The error indicates that the container image `localhost/ee-30:latest` is not available locally. The `--container-image` flag tells ansible-runner to use a specific execution environment image, but if that image has not been pulled from a registry or built locally, the container runtime (e.g., Podman or Docker) cannot find it. Option D is correct because the image must exist in the local container storage before ansible-runner can launch it.
