DevOps Ansible Automation - Practice Questions 2026

Core Concepts: Here, we dive into the heart of Ansible. Questions focus on Playbooks, YAML syntax, modules, and the fundamental execution flow that drives automation.

Intermediate Concepts: This level introduces logic and reusability. You will encounter questions regarding variables, facts, loops, and conditional statements that make your playbooks dynamic.

Advanced Concepts: Challenge yourself with complex topics such as Ansible Vault for security, Roles for modularity, and Handlers for task orchestration. This section is designed for those aiming for professional-level mastery.

Real-world Scenarios: Automation doesn't happen in a vacuum. These questions present "broken" scenarios or specific infrastructure requirements, requiring you to choose the most efficient and scalable solution.

Mixed Revision / Final Test: The ultimate cumulative exam. This timed set pulls from all previous sections to test your retention and readiness for a high-stakes environment.

Option 2: ignore_errors: yes

Option 3: failed_when: false

Option 4: error_handling: skip

Option 5: retry: no

Correct Answer: Option 2

Correct Answer Explanation: The ignore_errors: yes keyword is the standard Ansible directive used to ensure that even if a specific task fails, the play continues to execute subsequent tasks on that host.

Wrong Answers Explanation:

Option 3: failed_when is used to define what constitutes a failure, not to ignore an existing error state.

Option 4: error_handling is a generic term but not a functional Ansible parameter.

Option 5: retry is often associated with loops or network attempts, not global error suppression.

Option 2: ansible-vault modify

Option 3: ansible-vault rekey

Option 4: ansible-vault update

Option 5: ansible-vault encrypt --reset

Correct Answer: Option 3

Correct Answer Explanation: The rekey command is specifically designed to change the encryption key (password) of one or more vaulted files without needing to manually decrypt and re-encrypt them.

Wrong Answers Explanation:

Option 2: modify is used in other CLI tools but not in Ansible Vault.

Option 4: update does not exist in the Ansible Vault utility.

Option 5: encrypt --reset is incorrect syntax; encrypt is only for initial encryption of plain text files.

Option 2: {{ app_port }}

Option 3: { app_port }

Option 4: app_port.value

Option 5: var(app_port)

Correct Answer: Option 2

Correct Answer Explanation: Ansible uses Jinja2 templating syntax. Therefore, variables must be wrapped in double curly braces {{ }} to be interpolated correctly.

Wrong Answers Explanation:

Option 3: Single braces are used for dictionaries or sets in Python, not for variable substitution in Ansible.

Option 4: app_port.value suggests an object property that does not exist here.

Option 5: var() is a functional notation not used for basic variable referencing in playbooks.
