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.
Ansible Tower is configured with a dynamic inventory source from VMware vCenter. The playbook needs to limit execution to hosts with a specific custom attribute. How should this be achieved?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a smart inventory filter.
Smart inventories in Ansible Tower allow you to apply a filter (using Jinja2-style syntax) against an existing inventory source, such as a dynamic VMware vCenter source, to limit execution to hosts matching specific criteria like a custom attribute. This approach avoids modifying the source script or creating duplicate inventory sources, preserving the dynamic nature of the inventory while enabling targeted host selection.
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.
✗
Modify the VMware inventory script to filter hosts.
Why it's wrong here
Modifying the script is not scalable and bypasses Tower management.
✓
Use a smart inventory filter.
Why this is correct
Smart inventories can filter hosts based on custom attributes from the dynamic source.
Related concept
Read the scenario before looking for a memorised answer.
Inventory sources populate the entire inventory; filtering is not done at source level for specific attributes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think they need to modify the inventory source or script to filter hosts, not realizing that Tower's smart inventories provide a built-in, non-destructive way to apply filters on top of any existing inventory source.
Detailed technical explanation
How to think about this question
Smart inventories use a filter expression that is evaluated against the host variables from the source inventory, leveraging the same Jinja2 templating engine as Ansible playbooks. For VMware vCenter, custom attributes are stored as host variables (e.g., `custom_attributes['key']`), so a filter like `custom_attributes['department'] == 'engineering'` can be applied. This allows dynamic grouping without modifying the underlying inventory script or creating static entries, which is critical in environments where vCenter inventory changes frequently.
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.
