20+ practice questions focused on Manage inventories and credentials — one of the most tested topics on the Red Hat Certified Engineer EX294 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Manage inventories and credentials PracticeAn administrator needs to store a secret API token in Ansible Automation Controller so that it can be used in job templates without exposing the token in plain text. Which type of credential should be used?
Explanation: Option B is correct because a Machine credential in Ansible Automation Controller is designed to store SSH keys, passwords, and other authentication secrets for remote hosts. It can securely store an API token as a password field, which can then be referenced in job templates without exposing the token in plain text. This aligns with the requirement to store a secret API token for use in automation jobs.
A team uses Ansible Automation Controller with multiple organizations. Each organization has its own set of machines that require different SSH keys. The administrator wants to ensure that users from one organization cannot use credentials from another organization. What is the best way to achieve this isolation?
Explanation: In Ansible Automation Controller, credentials are scoped to organizations. By creating credentials within each organization and assigning organization-level access, the administrator ensures that credentials are only visible and usable by members of that organization. This leverages the built-in role-based access control (RBAC) that isolates resources by organization, preventing cross-organization credential access.
An Ansible playbook uses the `ansible_password` variable to connect to a Windows host. The value is stored in an encrypted Ansible Vault file. Which credential type in Automation Controller would allow the vault password to be supplied at runtime?
Explanation: Option C is correct because Automation Controller's Vault credential type is specifically designed to provide the vault password needed to decrypt Ansible Vault-encrypted variables like `ansible_password`. When a job runs, the controller uses this credential to unlock the vault file, allowing the playbook to access the encrypted value at runtime without exposing the plaintext password.
An administrator wants to create a custom credential type to store a third-party API key. The API key must be passed to the playbook as an environment variable `MY_API_KEY`. What is the correct Injector configuration in the custom credential type definition?
Explanation: Option D is correct because the Injector configuration for a custom credential type in Ansible Automation Platform uses the `env` key to map credential inputs to environment variables. The syntax `env: {"MY_API_KEY": "{{ api_key }}"}` correctly references the input field `api_key` using Jinja2 templating and assigns it to the environment variable `MY_API_KEY`, which the playbook can then access via `ansible_env.MY_API_KEY`.
A junior admin is troubleshooting why a job template fails with 'Permission denied' when connecting to a target host. The job template uses a machine credential that appears correct. What is the first thing to check?
Explanation: The error 'Permission denied' during SSH connection to a target host indicates an authentication failure. Since the machine credential appears correct, the most immediate cause is that the username or private key/password stored in the credential is incorrect or mismatched. This is the first thing to check because the credential directly controls authentication to the target host.
