- A
Define environment variables in the job template that references the inventory script, and use a credential type that injects those variables.
This is the correct approach: use custom credential types to inject environment variables into job templates.
- B
Attach the credential directly to the inventory script in the Ansible Tower UI.
Why wrong: Credentials cannot be attached directly to inventory scripts; they must be used in job templates.
- C
Store the API token in a file within the project repository and source it in the script.
Why wrong: Storing credentials in a repository is insecure and violates best practices.
- D
Embed the API token within the inventory script's JSON output.
Why wrong: No, embedding credentials in script output is insecure and unsupported.
EX294 Manage inventories and credentials Practice Question
This EX294 practice question tests your understanding of manage inventories and credentials. 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.
An administrator wants to use a custom inventory script to dynamically generate hosts in Ansible Tower. Which of the following is a valid approach to manage credentials for accessing the script's API?
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
Define environment variables in the job template that references the inventory script, and use a credential type that injects those variables.
Option A is correct because Ansible Tower (now Red Hat Ansible Automation Platform) allows custom credential types to inject environment variables into job runs. When a custom inventory script requires API authentication, you can define a credential type with injector configuration that sets environment variables (e.g., API_TOKEN, API_USER), then attach that credential to the job template. This keeps secrets out of scripts and repositories, following security best practices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think credentials can be directly attached to inventory scripts (Option B) or that storing tokens in project files is acceptable, when in fact Tower's credential system is designed to inject secrets via environment variables or extra vars, not via direct script attachment or file storage.
Trap categories for this question
Command / output trap
No, embedding credentials in script output is insecure and unsupported.
Detailed technical explanation
How to think about this question
Custom credential types in Ansible Tower use an injector configuration that maps credential inputs to environment variables (e.g., env: MY_API_TOKEN) or extra vars. When the inventory script runs, Tower sets these environment variables before execution, allowing the script to read them securely. This approach leverages Tower's built-in secret management and avoids hardcoding tokens, which is critical for dynamic inventories that query external APIs like cloud providers or CMDBs.
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.
