Question 1

Consider the following playbook:

- name: Frontend servers
  hosts: frontend
  become: yes
  tasks:
    - name: ???
      ansible.builtin.apt:
        name: nginx
        state: absent

Applying this playbook on an Ubuntu host with Nginx already installed:

• Will install nginx again.
• Will remove the nginx installation.
• Will do nothing since nginx is already installed.
• None of the above

Consider the below playbook:

- name: deploy app config
  template:
    src: app.xml.j2
    dest: /etc/app.xml
  notify:
    - restart memcached
    - restart apache

- name: deploy httpd config
  template:
    src: httpd.conf.j2
    dest: /etc/httpd/conf/httpd.conf
  notify:
    - restart apache

- name: deploy httpd config
  template:
    src: site.conf.j2
    dest: /etc/httpd/conf/site.conf
  notify:
    - restart apache
