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.
When building an execution environment with ansible-builder, a developer notices that the build process fails with an error about missing dependencies. The developer wants to ensure all required Python packages are installed in the execution environment. Which file should be used to specify additional Python packages?
meta/runtime.yml
Why wrong: Defines Ansible runtime requirements, not Python packages.
galaxy.yml
Why wrong: Defines collection metadata; not used for Python packages.
bindep.txt
Why wrong: Used for system-level package requirements, not Python.
requirements.txt
Standard file for Python dependencies in execution environments.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
requirements.txt
In Ansible Builder, the `requirements.txt` file is used to specify additional Python packages that should be installed in the execution environment. When building an execution environment, Ansible Builder reads this file and installs the listed packages via pip, ensuring all required Python dependencies are present.
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.
meta/runtime.yml
Why it's wrong here
Defines Ansible runtime requirements, not Python packages.
galaxy.yml
Why it's wrong here
Defines collection metadata; not used for Python packages.
bindep.txt
Why it's wrong here
Used for system-level package requirements, not Python.
requirements.txt
Why this is correct
Standard file for Python dependencies in execution environments.

Common exam traps
The trap here is that candidates confuse `bindep.txt` (for system packages) with `requirements.txt` (for Python packages), as both are used in execution environment builds but serve different dependency types.
Detailed technical explanation
Ansible Builder uses a multi-stage build process where `requirements.txt` is processed by pip in the build container to install Python packages. This file is typically placed in the `context/` directory of the execution environment definition. A common subtlety is that `bindep.txt` handles system packages like `libffi-dev` or `openssl`, while `requirements.txt` handles Python packages like `jmespath` or `netaddr`, and mixing them up leads to build failures.
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 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.
