EX294 Practice Question: Create content collections and execution environments
This EX294 practice question tests your understanding of create content collections and execution environments. 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.
During a collection development, a developer wants to include a Python dependency that is not available in the base image of the execution environment. Where should this dependency be declared?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
In the execution-environment.yml under 'dependencies' -> 'python'
In Ansible execution environments, Python dependencies that are not part of the base image must be declared in the `execution-environment.yml` file under the `dependencies` key, specifically within the `python` subkey. This file is used by `ansible-builder` to build a custom container image that includes those additional Python packages. The base image already contains a standard set of Python libraries, but any extra ones needed by a collection must be explicitly listed here to be installed 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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
In the execution-environment.yml under 'dependencies' -> 'python'
Why this is correct
Correct location for Python dependencies needed in the EE.
Related concept
Read the scenario before looking for a memorised answer.
✗
In the collection's requirements.yml under 'python'
Why it's wrong here
requirements.yml is for ansible-galaxy collection install, not EE.
✗
In the collection's galaxy.yml under 'dependencies'
Why it's wrong here
galaxy.yml is for collection metadata, not EE Python dependencies.
✗
In the collection's meta/runtime.yml under 'python_dependencies'
Why it's wrong here
Not a standard field.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the distinction between files used for building execution environments (`execution-environment.yml`) versus files used for publishing or runtime metadata (`galaxy.yml`, `meta/runtime.yml`), causing candidates to confuse where Python dependencies should be declared.
Detailed technical explanation
How to think about this question
The `execution-environment.yml` file is processed by `ansible-builder`, which uses the `dependencies.python` list to generate a `requirements.txt` file that is passed to `pip install` during the container build. This ensures the Python packages are installed in the correct layer of the image, leveraging Docker layer caching. A subtle behavior is that if a Python dependency is also available in the base image but at a different version, the `execution-environment.yml` declaration will override it, which can lead to unexpected version conflicts if not carefully managed.
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.
