EX294 Manage automation security and operations Practice Question
This EX294 practice question tests your understanding of manage automation security and operations. 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.
A junior administrator needs to rotate the password for a database user stored in an Ansible Vault-encrypted file (secrets.yml). The current password is unknown to the admin, but they have the vault password file (vault-pass.txt). The admin wants to edit the file securely without exposing the decrypted content in the terminal history or logs. Which command should they run?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Option A is correct because `ansible-vault edit` decrypts the file to a temporary file, opens it in the default editor (e.g., vi), and upon saving, re-encrypts it transparently. This prevents the decrypted content from ever being written to the terminal history or logs, as the editing happens in a secure temporary location that is cleaned up after the editor closes.
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.
This command only shows the decrypted content without allowing edits.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse `edit` with `decrypt` (thinking they need to decrypt first, then edit, then re-encrypt), or they may think `rekey` is for changing the content, when in fact it only changes the vault encryption password.
Trap categories for this question
Command / output trap
This command decrypts the file into plain text on disk, which could be left behind or exposed.
Detailed technical explanation
How to think about this question
Under the hood, `ansible-vault edit` uses a temporary file created with `mkstemp()` to ensure it is not written to a predictable location, and the editor is invoked via the `$EDITOR` or `$VISUAL` environment variable. The decrypted content is never stored in the user's shell history because the editing process is handled by the editor's own buffer, not by shell commands. In real-world scenarios, this is critical for compliance with standards like PCI-DSS or HIPAA, where secrets must never appear in plaintext in logs or command history.
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.

What is the correct answer to this question?
The correct answer is: ansible-vault edit --vault-password-file vault-pass.txt secrets.yml — Option A is correct because `ansible-vault edit` decrypts the file to a temporary file, opens it in the default editor (e.g., vi), and upon saving, re-encrypts it transparently. This prevents the decrypted content from ever being written to the terminal history or logs, as the editing happens in a secure temporary location that is cleaned up after the editor closes.
