Describe the architecture of Red Hat Ansible Automation Platform 2 and how its new features help with Ansible automation development.

Install automation content navigator and use it to run an existing playbook with a supported execution environment.

Create and manage Ansible Playbooks in a Git repository, following recommended practices.

Demonstrate and describe common recommended practices for developing and maintaining effective Ansible automation solutions.

Describe how Ansible Content Collections are used to distribute modules and plug-ins, and create plays that use content from them.

Search automation hub for Ansible Content Collections, and install them from the command line by name or by using a requirements.yml file.

Identify the automation execution environments provided by Red Hat and select the correct one for your use case.

Describe the architecture and use cases of the automation controller component of Red Hat Ansible Automation Platform.

Navigate and describe the automation controller web UI, and successfully launch a job using a job template, project, credential, and inventory.

Browse the current Ansible configuration by using automation content navigator.

Change configuration settings for automation content navigator with its configuration file, and determine where the configuration file is located.

Describe what dynamic inventories are, and install and use an existing script or plug-in as an Ansible dynamic inventory source.

Write static inventory files in YAML format.

Structure host and group variables by using multiple files per host or group, and use special variables to override the host, port, or remote user that Ansible uses for a specific host.

Control automatic privilege escalation at the play, role, task, or block level.

Configure tasks that can run before roles or after normal handlers, and simultaneously notify multiple handlers.

Label tasks with tags, and run only tasks labeled with specific tags, or start playbook execution at a specific task.

Optimize your playbook to run more efficiently, and use callback plug-ins to profile and analyze which tasks consume the most time.

Format, parse, and define the values of variables using filters.

Populate variables with data from external sources using lookup plug-ins.

Implement loops using structures other than simple lists by using lookup plug-ins and filters.

Use filters to inspect, validate, and manipulate variables containing networking information.

Run a task for a managed host on a different host, and control whether facts gathered by that task are delegated to the managed host or to the other host.

Tune the number of simultaneous connections that Ansible opens to managed hosts, and how Ansible processes groups of managed hosts through the play's tasks.

Tune the behavior of the serial directive when batching hosts for execution, abort the play if it fails for too many hosts, and create tasks that run only once for each batch or for all hosts in the inventory.

Create content collections and distribute them for reuse.

Build a custom automation execution environment image by using the ansible-builder command.

Validate that a custom automation execution environment works as expected by testing it with the ansible-navigator command, and then distribute the automation execution environment for reuse.

Run a playbook in automation controller that uses a content collection in the project or content provided by a specific automation execution environment.
