Question 1

What is the function of the 'serial' keyword in an Ansible playbook?

Accepted Answer

Controls how many hosts are updated at a time in a rolling deployment

The serial keyword enables rolling updates by specifying how many hosts (as a number or percentage) are processed per batch before moving to the next.

Question 2

Which Ansible feature allows you to test playbook syntax without executing any tasks on remote hosts?

Accepted Answer

--syntax-check flag

The --syntax-check flag parses the playbook and checks for YAML and Ansible syntax errors without connecting to or modifying any hosts.

Question 3

What does Ansible Molecule primarily provide for role developers?

Accepted Answer

A testing framework for Ansible roles and collections

Answer

Molecule provides a framework for testing Ansible roles by spinning up infrastructure (Docker, VMs), running playbooks, and verifying the resulting state.

Question 4

In Ansible, what is a 'fact cache' used for?

Accepted Answer

Storing gathered facts to disk so they can be reused across playbook runs

Answer

Fact caching stores gathered host facts to a backend (JSON files, Redis, etc.) so subsequent playbook runs can use cached facts without re-gathering them.

Question 5

Which network automation feature allows Ansible to build device configurations from templates?

Accepted Answer

Jinja2 templates with network modules

Ansible uses Jinja2 templates combined with network-specific modules (like cisco.ios.ios_config) to render and push device configurations.
