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.
A DevOps engineer is creating an execution environment for a team that needs both Ansible and the 'requests' Python library. The engineer creates an execution environment definition file (EE.yml) with the following content:
---
version: 3
images:
base_image:
name: registry.redhat.io/ansible-automation-platform-22/ee-minimal-rhel8:latest
options:
package_manager_path: /usr/bin/microdnf
dependencies:
python: requirements.txt
system: bindep.txt
What is missing from this definition to ensure the 'requests' library is installed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The requirements.txt file must contain 'requests'.
The execution environment definition file (EE.yml) specifies dependencies via external files like requirements.txt for Python packages. To install the 'requests' library, the requirements.txt file must explicitly list 'requests' as a dependency. Without it, the build process will not include the library, regardless of other configuration options.
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 package_manager_path should be /usr/bin/yum.
Why it's wrong here
RHEL8 minimal uses microdnf.
✓
The requirements.txt file must contain 'requests'.
Why this is correct
The requirements.txt file is referenced but the content is not shown; it must list requests.
Related concept
Read the scenario before looking for a memorised answer.
✗
The galaxy.yml file must be added to the dependencies section.
Why it's wrong here
Galaxy collections are separate from Python packages.
✗
The base image should be ee-supported-rhel8 instead.
Why it's wrong here
ee-minimal is appropriate for custom builds.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may focus on the package manager or base image details, overlooking that the Python dependency must be explicitly declared in the requirements.txt file referenced by the definition.
Detailed technical explanation
How to think about this question
Execution environment builds use the ansible-builder tool, which processes the definition file and resolves dependencies from the listed files. The requirements.txt file is passed to pip during the build phase, and each line specifies a Python package to install. If 'requests' is omitted, the build succeeds but the library is absent, leading to runtime failures when playbooks or modules attempt to import it. This is a common pitfall where candidates assume the base image includes all necessary Python libraries, but minimal images like ee-minimal-rhel8 contain only Ansible core dependencies.
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.
