EX294 Implement advanced Ansible automation Practice Question
This EX294 practice question tests your understanding of implement advanced ansible automation. 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 company uses Ansible Vault to encrypt sensitive data in playbooks. They have multiple environments (dev, test, prod) and use a separate vault password file for each environment. The passwords are stored in files named 'vault-pass-dev', 'vault-pass-test', and 'vault-pass-prod'. To run a playbook against the test environment, they use the command 'ansible-playbook site.yml -i test -e @test-vars.yml --vault-id test@vault-pass-test'. This runs successfully from the command line. However, when they define the same vault-id in an Ansible Tower credential and attempt to run the job, the job fails with 'ERROR! Decryption failed (no vault secrets would be found that could decrypt the vault encrypted file)' for a vault-encrypted variable file that was encrypted with a different vault ID (e.g., 'dev'). The team expects that Tower would use the provided vault credential to decrypt all vault-encrypted files. Which change should be made to ensure correct decryption in Tower?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add multiple vault credentials to the job template, one for each vault ID used in the project.
Ansible Vault with multiple vault IDs allows different passwords for different files. The Tower credential only provides one vault password per vault ID. To decrypt files encrypted with multiple vault IDs, multiple vault credentials or a single credential with multiple vault IDs must be configured. Option A correctly suggests using a single vault password file that contains the correct password for the file being decrypted, but the issue is that the file was encrypted with a different vault ID. Option B is the standard way in Tower: associate multiple vault credentials with the job template, each corresponding to a different vault ID. Option C is incorrect because Tower does not accept multiple passwords via one field. Option D would only work if the file was encrypted with the default ID.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Add multiple vault credentials to the job template, one for each vault ID used in the project.
Why this is correct
Tower can use multiple vault credentials to decrypt files with different vault IDs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enter all vault passwords separated by commas in the 'VAULT PASSWORD' field of a single credential.
Why it's wrong here
Tower expects a single password per credential.
✗
Re-encrypt all files with the same vault ID (e.g., 'default') to simplify the setup.
Why it's wrong here
This would require changing environment-specific encryption.
✗
Change the vault password file to contain the password for the vault ID that was used to encrypt the file.
Why it's wrong here
This would only fix one file, not multiple.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
