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.
Your organization uses Ansible Automation Platform 2.2 with private Automation Hub. You have developed a custom collection named 'my_company.network' that depends on 'cisco.ios' and 'vyos.vyos'. The collection is published in your private hub. You are building an execution environment using ansible-builder. The execution-environment.yml specifies 'EE_BASE_IMAGE: registry.redhat.io/ansible-automation-platform-22/ee-supported-rhel8:latest'. The dependencies section points to a requirements.yml file that includes your collection. When you run 'ansible-builder build', the build succeeds, but when running a playbook that uses modules from 'cisco.ios', you get an error 'module not found'. What is the most likely reason and the correct action to resolve it?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add 'cisco.ios' to the requirements.yml file used during the execution environment build
The execution environment build process uses the requirements.yml file to determine which collections to include in the image. If the custom collection 'my_company.network' depends on 'cisco.ios', but that dependency is not explicitly listed in the requirements.yml, the builder will not include 'cisco.ios' in the execution environment. Adding 'cisco.ios' to the requirements.yml ensures it is installed during the build, making the module available at runtime.
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.
✗
Reinstall the collection on the controller node using 'ansible-galaxy collection install'
Why it's wrong here
The issue is in the execution environment, not the controller.
✗
Use a different base image that includes 'cisco.ios'
Why it's wrong here
While possible, the best practice is to specify dependencies explicitly.
✗
Update the collection metadata to include dependencies and rebuild
Why it's wrong here
Collection metadata does not automatically get pulled into execution environment builds.
✓
Add 'cisco.ios' to the requirements.yml file used during the execution environment build
Why this is correct
Explicitly listing the dependency ensures it is included in the execution environment.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume collection dependencies declared in metadata are automatically resolved during the execution environment build, but ansible-builder only installs collections explicitly listed in requirements.yml, not their transitive dependencies.
Detailed technical explanation
How to think about this question
The ansible-builder tool processes the execution-environment.yml and the referenced requirements.yml to construct a container image. It runs 'ansible-galaxy collection install' with the requirements.yml file, but it does not recursively resolve dependencies declared in collection metadata (e.g., galaxy.yml). This means any transitive dependency must be explicitly listed in the requirements.yml. In real-world scenarios, if a collection depends on another that is not in the base image or explicitly included, the module will be missing at runtime, leading to 'module not found' errors.
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.
