Question 13

Correct answer: B

B.

This playbook configures a web server to host a static website by performing three tasks. First, it creates a document root directory for storing the website files. Second, it deploys a sample HTML file to this directory to serve as the website's homepage. Finally, it ensures the nginx service is installed, started, and enabled at boot. This setup guarantees that the static website is accessible and automatically starts with the server.

Line-by-Line Explanation:

1. Define Target Hosts:

   - hosts: all

   • Specifies that the playbook will run on all managed nodes listed in the inventory.

2. Create Document Root Directory:

     - name: Configure document root
       ansible.builtin.file:
         path: /var/www/html
         state: directory

   • Creates the /var/www/html directory, which will serve as the document root for the static website.

   • The state: directory ensures the specified path exists as a directory.

3. Deploy Sample HTML File:

     - name: Deploy sample HTML file
       ansible.builtin.copy:
         src: /path/to/index.html
         dest: /var/www/html/index.html

   • Copies a sample HTML file (index.html) from the local system to the document root directory on the managed node.

   • The src parameter specifies the file's source location, while dest specifies the destination location.

4. Start and Enable nginx:

     - name: Start and enable nginx
       ansible.builtin.service:
         name: nginx
         state: started
         enabled: yes

   • Ensures the nginx service is started and enabled to run at boot.

   • The state: started parameter ensures the service is running, while enabled: yes ensures it starts automatically after a reboot.
