EX294 Practice Question: Create content collections and execution environments
This EX294 practice question tests your understanding of create content collections and execution environments. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 execution environment is built using ansible-builder. The definition file includes a base image from registry.redhat.io. After building, the container runs but ansible-navigator can't find the EE. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The EE was not pushed to a registry accessible by ansible-navigator.
The most likely cause is that the execution environment (EE) was built locally but not pushed to a registry that `ansible-navigator` can access. By default, `ansible-navigator` pulls EEs from a container registry (e.g., `registry.redhat.io` or a private registry) specified in its configuration; it does not automatically discover locally built images. If the EE is only present in the local Docker/Podman store, `ansible-navigator` will fail to find it, resulting in a runtime error.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The EE was not pushed to a registry accessible by ansible-navigator.
Why this is correct
ansible-navigator by default pulls EEs from a registry; a locally built EE must be pushed to a configured registry.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
ansible-navigator uses a different Python interpreter.
Why it's wrong here
The Python interpreter is inside the EE container; this does not affect discovery.
✗
The base image is not compatible with the installed collections.
Why it's wrong here
This would cause runtime errors, not failure to find the EE.
✗
The EE was not tagged correctly.
Why it's wrong here
Incorrect tagging would cause issues when referencing, but if it's local, ansible-navigator can find it by ID.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume `ansible-navigator` can use any locally built container image without pushing it to a registry, overlooking the default pull behavior that requires registry access.
Detailed technical explanation
How to think about this question
`ansible-navigator` uses the `--eei` or `execution-environment-image` setting to specify the EE image, which it pulls via Podman or Docker from a registry. If the image is only local, `ansible-navigator` will attempt to pull it from the registry and fail with a `404` or `image not found` error. This is a common pitfall when testing EEs locally: the builder creates the image in the local store, but `ansible-navigator` expects it in a registry unless explicitly configured with `--pull-policy never` or `container-engine pull-policy: missing`.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
