EX294 Manage inventories and credentials Practice Question
This EX294 practice question tests your understanding of manage inventories and credentials. 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.
An administrator needs to provide a set of credentials to a job template that requires a machine credential for SSH and a source control credential for the project. What is the correct way to associate these credentials?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Assign both a machine credential and a source control credential to the job template
Option D is correct because Ansible Tower/AWX allows multiple credentials of different types to be assigned to a single job template. A machine credential handles SSH authentication for target hosts, while a source control credential manages authentication for the project repository (e.g., Git). This separation follows Ansible's modular credential design, where each credential type serves a distinct purpose and can be independently managed.
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.
✗
Define the source control token in the playbook using the 'set_fact' module
Why it's wrong here
Embedding credentials in playbooks is insecure and not recommended.
✗
Create a single credential that includes both SSH key and source control token
Why it's wrong here
Credentials are typed; a machine credential cannot hold source control data.
✗
Store the source control token as an extra variable in the job template
Why it's wrong here
Extra variables are not secure for credential data and are not the standard way.
✓
Assign both a machine credential and a source control credential to the job template
Why this is correct
Job templates can have multiple credentials of different types.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates think a single credential must contain all authentication data, but Ansible Tower explicitly separates credential types by function, and a job template can accept multiple credentials of different types simultaneously.
Detailed technical explanation
How to think about this question
Under the hood, Ansible Tower uses credential plugins to inject authentication into job runs: machine credentials provide SSH keys or passwords via ssh-agent or --private-key, while source control credentials supply tokens or SSH keys for Git operations during project sync. This separation allows role-based access control (RBAC) to grant different users access to different credential types, and credentials are encrypted at rest in the database using AES-256. In real-world scenarios, a team might have read-only source control access for automation but full SSH access to production hosts, requiring distinct credentials.

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.
