Ansible Automation Technology & Digital Applications 4

Question 1

What is the purpose of the 'register' keyword combined with 'until' in Ansible?

Accepted Answer

Retries a task until the registered output meets a condition

Answer

Combining register with until, retries, and delay creates a polling loop that retries a task until the captured output satisfies a specified condition.

Question 2

In Ansible automation for cloud environments, what does 'infrastructure as code' mean in practice?

Accepted Answer

Defining and managing cloud resources through versioned playbooks and templates

Answer

Infrastructure as code with Ansible means cloud resources are defined in playbooks stored in version control, enabling repeatable, auditable provisioning.

Question 3

Which Ansible module enables idempotent management of cron jobs on Linux systems?

Accepted Answer

ansible.builtin.cron

Answer

The ansible.builtin.cron module adds, modifies, or removes cron jobs idempotently, ensuring the desired state is applied without duplication.

Question 4

What does Ansible's 'check mode' (--check) do differently from a normal run?

Accepted Answer

Simulates changes and reports what would happen without making actual modifications

Answer

Check mode (dry run) causes Ansible to report what changes it would make without actually executing them on the remote systems.

Question 5

When automating patch management with Ansible, which approach ensures minimal downtime for web servers?

Accepted Answer

Use serial with load balancer module to drain and patch nodes one at a time

Answer

Combining the serial keyword with load balancer modules (like bigip_pool_member) drains traffic from each node before patching, ensuring continuous availability.
