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.
A system administrator wants to build an Ansible execution environment using ansible-builder. Which file format is required to define the base image, dependencies, and additional Python packages for the build?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
execution-environment.yml
Option A is correct because `ansible-builder` requires an `execution-environment.yml` file to define the build context, including the base image (under `version: 1`), system-level dependencies (under `dependencies: system:`), and additional Python packages (under `dependencies: python:`). This file is the mandatory definition file for building an Ansible Execution Environment (EE) using `ansible-builder build`.
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.
✓
execution-environment.yml
Why this is correct
Correct. This is the standard file for ansible-builder.

✗
ansible-navigator.yml
Why it's wrong here
Incorrect. This file configures ansible-navigator, not the execution environment build.
✗
Containerfile
Why it's wrong here
Incorrect. While a Containerfile can be used to build a container, ansible-builder leverages execution-environment.yml to generate one.
✗
requirements.yml
Why it's wrong here
Incorrect. requirements.yml is used for installing roles and collections via ansible-galaxy.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the build input file (`execution-environment.yml`) with the runtime configuration file (`ansible-navigator.yml`) or with the generated output (`Containerfile`), leading them to pick the wrong option.
Detailed technical explanation
How to think about this question
Under the hood, `ansible-builder` reads the `execution-environment.yml`, resolves the base image (e.g., `quay.io/ansible/ansible-runner:latest`), and generates a `Containerfile` that installs system packages via `dnf` and Python packages via `pip` into a layered image. A subtle behavior: if you specify a Python package that conflicts with the base image's Python environment, the build may fail silently or produce a broken EE, so testing with `ansible-navigator run` after the build is critical.
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.
