EX294 Practice Question: Create content collections and execution environments
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.
An organization uses custom Ansible plugins stored in a collection. A junior admin reports that after updating the collection to version 2.0.0, a playbook that uses a custom filter plugin fails with 'undefined filter'. What is the most likely cause?
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
✓
The filter plugin was placed in the wrong directory inside the collection.
In Ansible collections, filter plugins must reside in the `plugins/filter/` directory within the collection structure. If the plugin is placed in the wrong directory (e.g., `plugins/modules/` or `plugins/lookup/`), Ansible will not load it as a filter, resulting in an 'undefined filter' error. The collection update to version 2.0.0 likely reorganized the directory structure, causing the filter to be misplaced.
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The playbook uses an outdated syntax that is incompatible with the new collection.
Why it's wrong here
Version updates typically maintain backward compatibility for filter syntax.
✓
The filter plugin was placed in the wrong directory inside the collection.
Why this is correct
Filter plugins must reside in plugins/filter/ directory.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The playbook does not use the fully qualified collection name (FQCN) for the filter.
Why it's wrong here
FQCN is not required if the collection is listed in the playbook's collections keyword.
✗
The collection's metadata file galaxy.yml is missing a dependency declaration.
Why it's wrong here
Missing dependencies would cause a different error.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the error is due to syntax or naming (FQCN), but the core issue is the strict directory structure requirement for Ansible plugin loading, which is a fundamental concept in collection development.
Trap categories for this question
Keyword trap
FQCN is not required if the collection is listed in the playbook's collections keyword.
Detailed technical explanation
How to think about this question
Ansible's plugin loader scans specific subdirectories under `plugins/` based on plugin type: `filter` for filters, `modules` for modules, etc. The `undefined filter` error occurs when the loader cannot find the plugin in the expected path. In a real-world scenario, a junior admin might accidentally move the filter file during a collection restructure, or the collection's `setup.py` or `galaxy.yml` might not correctly list the filter plugin, but the most common cause is incorrect directory placement.

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.
