EX294 Manage inventories and credentials Practice Question
This EX294 practice question tests your understanding of manage inventories and credentials. 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.
A system administrator is managing Ansible Tower and wants to use an Azure Resource Manager credential to provision virtual machines. However, the credential fails authentication with the error '401 Unauthorized'. Which action should the administrator take to resolve the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Verify the client secret in the credential matches the one configured in Azure Active Directory.
The 401 Unauthorized error when using an Azure Resource Manager credential in Ansible Tower indicates that the authentication token or secret used to authenticate with Azure Active Directory is invalid or mismatched. Option B is correct because verifying that the client secret stored in the Tower credential exactly matches the one configured in Azure Active Directory resolves the authentication failure, as Azure AD uses OAuth 2.0 client credentials flow where the client secret is required for token acquisition.
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.
✗
Regenerate the SSH key pair and update the credential.
Why it's wrong here
Azure Resource Manager credentials use OAuth2, not SSH keys.
✓
Verify the client secret in the credential matches the one configured in Azure Active Directory.
Why this is correct
A mismatch in client secret causes 401 errors.
Related concept
Read the scenario before looking for a memorised answer.
✗
Add the credential as a playbook-level variable instead of a Tower credential.
Why it's wrong here
Cloud credentials should be defined in Tower, not hard-coded in playbooks.
✗
Generate a new API token from Azure and paste it into the credential.
Why it's wrong here
Azure Resource Manager uses a client secret, not an API token.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse SSH key authentication (used for Linux hosts) with Azure AD OAuth authentication, leading them to select option A, or they mistakenly think generating a new API token (option D) is the correct fix for Azure credentials.
Detailed technical explanation
How to think about this question
Azure Resource Manager credentials in Ansible Tower use OAuth 2.0 client credentials grant, where Tower sends a POST request to https://login.microsoftonline.com/{tenant_id}/oauth2/token with the client_id and client_secret to obtain an access token. The 401 error typically occurs when the client secret has expired, been rotated, or is mistyped; Azure AD returns a 401 with error 'invalid_client' if the secret does not match. In real-world scenarios, administrators must ensure the secret is copied exactly, as Azure AD does not display the full secret after creation, and Tower stores it encrypted in its database.
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.
