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.
Network Topology
Given the command and error above, what is the most likely cause of the failure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Network Topology
A
The vault file 'vault@prompt' does not exist.
Why wrong: Error indicates it's an encryption issue, not missing file.
B
The vault password file must be encrypted with ansible-vault.
Why wrong: The password file itself is not encrypted.
C
The --vault-id syntax is incorrect; 'vault@prompt' should be a label and password source, not a vault file.
Users often confuse vault-id with vault file; proper usage is '--vault-id @prompt' or '--vault-id myvault@prompt'.
D
The --check flag is incompatible with vault encryption.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The --vault-id syntax is incorrect; 'vault@prompt' should be a label and password source, not a vault file.
The `--vault-id` option expects a label and a password source (e.g., `vault@prompt` means the label is 'vault' and the password is prompted interactively). The error indicates that Ansible is interpreting the entire string as a vault file path, which fails because no file named 'vault@prompt' exists. Option C correctly identifies that the syntax is being misapplied.
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.
✗
The vault file 'vault@prompt' does not exist.
Why it's wrong here
Error indicates it's an encryption issue, not missing file.
✗
The vault password file must be encrypted with ansible-vault.
Why it's wrong here
The password file itself is not encrypted.
✓
The --vault-id syntax is incorrect; 'vault@prompt' should be a label and password source, not a vault file.
Why this is correct
Users often confuse vault-id with vault file; proper usage is '--vault-id @prompt' or '--vault-id myvault@prompt'.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The --check flag is incompatible with vault encryption.
Why it's wrong here
--check works with vault.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the `--vault-id` argument with a vault file path, assuming the error means the file is missing, rather than recognizing that the syntax requires a label and source separated by `@`.
Detailed technical explanation
How to think about this question
The `--vault-id` syntax is `label@source`, where `source` can be `prompt`, a file path, or an executable script. When using `prompt`, Ansible reads the password interactively from the terminal; the label is arbitrary and used for identifying multiple vaults. A common real-world scenario is using multiple vault IDs (e.g., `dev@prompt` and `prod@file`) to manage different environments, where incorrect syntax causes Ansible to attempt opening a file named literally 'dev@prompt'.
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.
