Adaface Sample Ansible Questions

Analyze the following Ansible playbook, which is designed to set up and verify a web server. Determine the correct order of task execution, including the handler invocation:

In what order will the tasks and handlers be executed?

A: Install web server, Start web server, Verify web server, Notify failure, Restart web server (if notified)
            B: Install web server, Start web server, Restart web server (if notified), Verify web server, Notify failure (if failed)
            C: Install web server, Restart web server (if notified), Start web server, Verify web server, Notify failure (if failed)
            D: Install web server, Start web server, Verify web server, Notify failure (if failed), Restart web server (if notified)
            E: Install web server, Verify web server, Start web server, Restart web server (if notified), Notify failure (if failed)
            F: Install web server, Start web server, Verify web server (if previous task failed), Notify failure, Restart web server (if notified)

You are a senior Ansible engineer tasked with writing a playbook to configure a set of web servers. The playbook should iterate over a list of packages and install them. However, if a package installation fails, the playbook should record the failed package name and continue with the next package without failing the entire playbook. The playbook also needs to generate a report at the end, listing all successfully installed packages and any that failed to install. Below is the pseudo code for the main task:

Select the correct way to complete this playbook:

A: Add a block with a rescue section after the loop to capture failed packages.
            B: Use failed_when in the loop to prevent the task from failing and update the lists accordingly.
            C: Use a when condition inside the loop to check package_result.failed and update the lists.
            D: Add a handler triggered on package installation failure to update the failed_packages list.
            E: Use a Jinja2 template in a separate task to generate the report after the loop.
            F: Implement a custom Ansible module for package installation and failure handling.

Consider an Ansible playbook that is designed to set up a web server. The playbook needs to assign a variable named `webserver_port` based on the operating system of the target host. The default port should be 80, but if the target host is running Ubuntu, the port should be set to 8080. Below is the pseudo code for the task:

Choose the correct statement regarding the execution of this task:

A: The task will fail because the comparison in the conditional statement is incorrect.
            B: The task will assign port 8080 for all Debian-based distributions, including Ubuntu.
            C: The task will always assign port 80, regardless of the operating system.
            D: The task will assign port 8080 only if the `ansible_os_family` variable is exactly 'Ubuntu'.
            E: The task will fail because `set_fact` does not support conditional assignments.
            F: The task will assign port 8080 for Ubuntu and port 80 for all other operating systems.
