RHCE Ansible Troubleshooting Quiz

1. You receive the error 'No module named 'jinja2'.' How do you resolve this?

Install Jinja2: pip install jinja2

Update Ansible to the latest version

Install the jinja2-ansible package

Add jinja2 to the requirements.txt file

2. You need to see which tasks will run without executing them. Which command previews the execution plan?

Ansible-playbook playbook.yml --list-tasks

Ansible-playbook playbook.yml --preview

Ansible-playbook playbook.yml --dry-run

Ansible-playbook playbook.yml --validate

3. A handler never executes after a task notifies it. What is the most likely cause?

The handler name does not exactly match the notify statement

The task status is 'changed' instead of 'ok'

The become directive is missing

The handler is defined in a different file

4. You receive 'ERROR! Unexpected Exception: name 'undefined_var' is not defined.' How do you fix this?

Use default filter: {{ undefined_var | default('value') }}

Restart the Ansible service

Update the inventory file

Reinstall Ansible

5. A playbook fails because the ansible_user variable is not set for a group. Where should you define it?

In group_vars/groupname or inventory file

In the playbook vars section

In ansible.cfg

In the task itself

6. You need to skip a task conditionally. Which keyword allows you to skip based on a condition?

Skip_when: condition

When: condition

Ignore_if: condition

Skip: condition

7. A task uses a Jinja2 filter but returns an error. What is the first troubleshooting step?

Verify the filter syntax and ensure the variable is defined

Update Ansible to the latest version

Disable Jinja2 templating in ansible.cfg

Use raw module instead

8. Your playbook fails because a file path contains spaces and is not quoted. Where should you quote the path?

In the YAML task definition: path: '/path with spaces'

In the inventory file

In the ansible.cfg configuration

In the become_user directive

9. When debugging a loop, you want to see each iteration's value. Which keyword displays the loop variable?

Debug: var=item

Debug: msg='{{ item }}'

Both a and b are correct

Print: item

10. A playbook task times out while waiting for a service to start. Which parameter adjusts the timeout?

Timeout or async_val

Wait_timeout

Max_retries

Connection_timeout

11. You run an Ansible playbook and receive the error 'fatal: [host1]: UNREACHABLE! All retries exhausted.' What is the most common cause?

SSH connectivity or authentication failure

Insufficient disk space on the target host

Ansible version mismatch

Missing Python interpreter on control node

12. A module fails with 'localhost is not a valid hostname.' What is the likely cause?

The inventory file uses 'localhost' but ansible_connection is not set to local

SSH keys are not configured for localhost

Python 3 is not installed

The firewall is blocking connections

13. Your playbook uses a registered variable from a previous task. The variable appears empty. What should you check first?

Verify the previous task executed successfully and check stdout

Increase the memory allocation on the control node

Restart the Ansible service

Reinstall Ansible plugins

14. A host is not being targeted by your playbook. You suspect an inventory issue. How do you list all hosts matching a pattern?

Ansible all -i inventory.ini --list-hosts

Ansible-playbook --list-hosts inventory.ini

Ansible-inventory --hosts

Ansible-config list-hosts

15. You need to test a playbook without making actual changes. Which flag enables check mode?

--check

--dry-run

--validate

--test

16. A module reports 'Permission denied' when executing a command. What is the most likely solution?

Add become: yes and become_user to the task

Increase the timeout value

Change the ansible_connection to local

Update the SSH key pair

17. Your inventory file syntax is invalid. Which command checks inventory syntax without running tasks?

Ansible-inventory --list

Ansible-playbook --syntax-check

Ansible-inventory --parse

Ansible --check-inventory

18. A task fails because a variable is undefined. How do you prevent the playbook from stopping at that error?

Use ignore_errors: yes on the task

Define the variable in group_vars

Add the variable to the inventory file

Use the set_fact module before the task

19. Which flag enables verbose debugging output in Ansible to troubleshoot module execution?

-v or -vv or -vvv

--debug-mode

--trace

--log-level

20. Your playbook fails with 'ERROR! The field 'tasks' has an invalid value.' What likely caused this?

YAML syntax error or incorrect indentation

Missing become_user directive

Undefined variable in the task

Invalid SSH key permissions
