EX294 Practice Question: Create content collections and execution environments
An engineer is preparing to build an execution environment using `ansible-builder`. The build must include several collections and also install additional Python packages. Which two files are used to declare these dependencies? (Choose two.)
⚠ Common exam trap
Many candidates confuse `bindep.txt` (system packages) with `requirements.txt` (Python packages), or assuming that `execution-environment.yml` directly lists all dependencies.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
requirements.yml
The correct files are `requirements.yml` for Ansible collections and roles, and `requirements.txt` for Python packages. These are referenced by the `execution-environment.yml` file and are used by `ansible-builder` to install the necessary dependencies into the execution environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
requirements.yml
Why this is correct
`requirements.yml` is used to list Ansible collections and roles that should be installed into the execution environment. It is the standard file for declaring collection dependencies, including those from Automation Hub or Galaxy. This file ensures the required collections are present.
- ✗
galaxy.yml
Why it's wrong here
`galaxy.yml` is metadata for an Ansible collection, not for an execution environment. It defines the collection's own dependencies, but it is not used by `ansible-builder` to determine what to install into the execution environment. It is irrelevant in this context.
- ✗
execution-environment.yml
Why it's wrong here
`execution-environment.yml` is the main definition file that references the dependency files, but it does not directly list collections or Python packages. It specifies the base image and points to `requirements.yml`, `bindep.txt`, and `requirements.txt`. It is not the file where dependencies are declared.
- ✗
bindep.txt
Why it's wrong here
`bindep.txt` is used to specify system-level package dependencies, such as RPM packages, needed by the execution environment. It does not handle Python packages; those are managed separately. Therefore, it is not the correct file for Python dependencies.
- ✓
requirements.txt
Why this is correct
`requirements.txt` is a standard Python requirements file used by `ansible-builder` to install additional Python packages into the execution environment. It lists packages with optional version specifiers, ensuring the required Python libraries are available for modules and plugins.
