Ansible Automation Ansible Playbooks 5

Question 1

Which playbook feature allows you to apply a single task to a different host than the one being iterated over?

Accepted Answer

delegate_to

Answer

`delegate_to` runs a task on a specified host while retaining the inventory variables of the current host.

Question 2

When using `delegate_to` with `delegate_facts: true`, what is the result?

Accepted Answer

Facts are gathered on the delegated host and stored under the delegated host's name

Answer

`delegate_facts: true` assigns gathered facts to the delegated host's namespace rather than the current host's.

Question 3

What does the `serial` keyword control in an Ansible play?

Accepted Answer

How many hosts are processed in each batch during a rolling update

Answer

`serial` defines the batch size for rolling updates, letting you update a percentage or fixed number of hosts at a time.

Question 4

Which playbook directive prevents SSH host key checking for all tasks in a play?

Accepted Answer

Setting ANSIBLE_HOST_KEY_CHECKING=False as an environment variable or in ansible.cfg

Answer

Host key checking is controlled via the `host_key_checking` setting in ansible.cfg or the `ANSIBLE_HOST_KEY_CHECKING` environment variable, not a play-level directive.

Question 5

In a playbook, what is the purpose of `become_method: sudo`?

Accepted Answer

Specifies the privilege escalation tool to use

Answer

`become_method` selects the privilege escalation mechanism; valid options include `sudo`, `su`, `pbrun`, `pfexec`, and others.
