Ansible Automation Technology & Digital Applications 5

Question 1

What is the purpose of Ansible's 'lookup' plugins?

Accepted Answer

Retrieve data from external sources like files, databases, or APIs for use in playbooks

Answer

Lookup plugins fetch data from external sources (files, environment variables, HashiCorp Vault, etc.) and return values that can be used as variable data in playbooks.

Question 2

In Ansible automation, what does 'idempotency' mean for technology operations teams?

Accepted Answer

Running the same playbook multiple times produces the same result without unintended side effects

Answer

Idempotency means a playbook can be applied repeatedly and will only make changes when the current state differs from the desired state, preventing configuration drift.

Question 3

Which Ansible tool analyzes playbooks for common mistakes, style issues, and best practice violations?

Accepted Answer

ansible-lint

Answer

ansible-lint scans playbooks and roles for rule violations, deprecated syntax, and best practice issues to improve code quality before execution.

Question 4

What mechanism does Ansible use to notify administrators of task failures in automated pipelines?

Accepted Answer

Callback plugins that can send alerts to Slack, email, or monitoring systems

Answer

Callback plugins intercept playbook events (task failure, play complete) and can forward notifications to external systems like Slack, Splunk, or monitoring platforms.

Question 5

When managing heterogeneous environments, how does Ansible handle different OS families with a single playbook?

Accepted Answer

Using 'when' conditions with ansible_os_family or ansible_distribution facts

Answer

Conditional 'when' clauses using gathered facts like ansible_os_family allow a single playbook to branch logic for different operating systems (RedHat, Debian, Windows, etc.).
