Ansible Vault: Including Encrypted Variables via include_vars
This EX294 practice question tests your understanding of manage task execution and roles. 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.
Exhibit
[root@controller ~]# ansible-playbook -i inventory.ini site.yml --ask-vault-pass
Vault password:
PLAY [all] ***************************************************************
TASK [Gathering Facts] ***************************************************
ok: [server1]
TASK [common : Install httpd] ********************************************
fatal: [server1]: FAILED! => {"changed": false, "msg": "The task includes an option with an undefined variable. The error was: 'vault_httpd_port' is undefined"}
PLAY RECAP ****************************************************************
server1 : ok=1 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
Refer to the exhibit. An administrator runs an Ansible playbook and receives the error shown. The playbook uses a variable 'vault_httpd_port' that should be stored in an encrypted vault file. Which step should the administrator take first to resolve the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
Re-encrypt the vault file with a different password.
Why wrong: The password is not necessarily the issue; the vault file may not be included in the playbook.
B
Add 'vault_httpd_port' to the group_vars/all.yml file without encryption.
Why wrong: This would expose the variable but not use vault encryption.
C
Use the --ask-vault-pass option again with a different password.
Why wrong: Re-entering the same password won't help if the vault file is not included.
D
Ensure the vault file is referenced in the playbook using include_vars or vars_files, and that the vault password is correct.
The vault file must be included in the playbook, and the vault password must be provided correctly.

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.
