Your organization uses Red Hat Ansible Automation Platform (AAP) to manage job execution. You have created a job template that runs a playbook to configure application servers. The playbook uses a custom credential to access a remote database. Recently, the job started failing with 'Authentication failed' when connecting to the database.

Which step should you take to troubleshoot and resolve the issue?

You are managing a web application deployment using Ansible. The application requires a specific version of a library (libapp) to be installed on all web servers. Your current playbook uses the role 'web' which includes a task to install libapp version 1.2. However, after a recent update, the role's defaults now specify libapp version 2.0, but you must keep version 1.2 for compatibility. You have defined a variable 'lib_version' in the playbook's vars section with value '1.2'. The role's task uses the variable 'libapp_version' (not 'lib_version'). The play fails because 'libapp_version' is undefined. What is the best way to resolve this issue without modifying the role?

Your team uses ansible-pull to manage configuration of a large number of remote nodes. Each node is configured to pull the latest playbook from a Git repository every 30 minutes. Recently, some nodes started reporting 'ERROR! the role 'base' was not found'. The playbook depends on roles from a requirements.yml file that is stored in the same repository. The ansible-pull command on each node uses the default roles path (~/.ansible/roles). The Git repository contains the requirements.yml file but does not contain the actual role directories. What is the most likely cause and solution?

An administrator wants to ensure a role's tasks are executed only on certain hosts. Which approach should they use?

You are responsible for managing a large fleet of web servers running Red Hat Enterprise Linux 8. You have an Ansible playbook that deploys a custom web application. The playbook uses several roles from Ansible Galaxy and includes tasks that require root privileges. Recently, users reported that the deployment fails intermittently with the error 'Timeout (12s) waiting for privilege escalation prompt'. You suspect that the issue is related to the become method and the SSH connection. The current inventory uses 'ansible_user: deploy' and 'ansible_become: yes' with default settings. The 'deploy' user has sudo privileges with NOPASSWD for all commands. However, the timeout occurs only on high-latency connections. Which change would most effectively resolve the timeout issue?

Which TWO statements about Ansible roles are true?

You need to run an Ansible playbook every hour to update a dynamic inventory file from a CMDB API. The playbook is stored in /opt/ansible/update_inventory.yml. You want to schedule the execution using a cron job on the control node. The control node runs Red Hat Enterprise Linux 9. The playbook uses Ansible Vault to decrypt API credentials, and the vault password is stored in /etc/ansible/.vault_pass. Which cron entry will execute the playbook hourly?

An Ansible role has a complex dependency tree. The administrator wants to ensure that dependencies are installed before the main role tasks. Which file should be used to define dependencies?

Refer to the exhibit. The administrator runs the playbook with the 'deploy' tag, but all tasks are skipped. What is the most likely reason?

A team is automating server configuration using Ansible. They have a custom role 'security' that updates firewall and SSH settings. They notice that when they apply the role to multiple hosts, the SSH configuration changes sometimes fail because the firewall blocks the SSH port before the SSH configuration is updated. They need to ensure that SSH configuration is updated first, then firewall rules are applied. They have defined both tasks in the same role. What should they do?

Refer to the exhibit. An Ansible playbook task fails with 'Missing sudo password'. The playbook runs against a server where the remote user 'admin' has sudo privileges but requires a password. Which configuration change would resolve this issue?

An Ansible playbook uses the 'block' and 'rescue' directives. Which two statements are true about this construct? (Choose two.)

You are managing a fleet of 50 RHEL 8 servers that host a critical web application. Your Ansible control node runs RHEL 8 with Ansible 2.9. The application requires a specific package 'app-pkg' that is only available from a private YUM repository. The repository is configured on each server via a role 'repo_config'. Recently, after a security update, the repository GPG key was changed. Now, when you run the playbook to install 'app-pkg' on all servers, it fails on some servers with the error: "GPG check FAILED: key ID mismatch". On other servers, the installation succeeds. All servers have the same OS version and are configured identically via the same role. The playbook uses the 'yum' module with 'state: present'. You verify that the GPG key file on the control node is the correct new key and that the role copies it to the servers. What is the most likely cause and the best course of action?
