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 Ansible Tower administrator wants to allow a team to run playbooks against a set of production web servers without giving them direct SSH access to the hosts. Which inventory configuration approach should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a smart inventory and use the 'prod_web' tag to filter hosts
Smart inventories in Ansible Tower allow you to define a dynamic set of hosts based on a filter, such as a tag (e.g., 'prod_web'). This enables the team to run playbooks against production web servers without granting them direct SSH access to the hosts, as Tower manages the SSH connections centrally using its own credentials.
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.
✗
Use the ad hoc inventory feature to specify hosts at launch time
Why it's wrong here
Ad hoc inventories are temporary and not suitable for persistent team access.
✗
Define a group variable for production web servers in the inventory
Why it's wrong here
Group variables define settings for hosts in a group but do not create groups automatically.
✗
Create a static inventory and add each web server manually
Why it's wrong here
Static inventories require manual updates and are not scalable for dynamic environments.
✓
Create a smart inventory and use the 'prod_web' tag to filter hosts
Why this is correct
Smart inventories dynamically filter hosts based on criteria like tags, enabling automatic grouping.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse smart inventories with static inventories or group variables, failing to recognize that smart inventories are the only option that provides dynamic, tag-based host filtering without requiring direct SSH access.
Detailed technical explanation
How to think about this question
Smart inventories use the Ansible Tower inventory API to query hosts based on criteria like tags, facts, or group membership, returning a filtered subset dynamically at runtime. This approach integrates with Tower's credential system, where the team's role-based access can be limited to launching jobs against the smart inventory without ever exposing SSH keys or host IPs directly to users.
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.
