Hands-On Practice is Critical
- The RHCE is 100% performance-based with no multiple choice questions - you must actually configure systems
- Build a lab environment with at least 3-5 virtual machines (1 control node, 4 managed nodes)
- Practice every task multiple times until you can complete it without referencing documentation
- Use VirtualBox or KVM with CentOS/RHEL 8 or 9 for realistic exam conditions
- Take snapshots of your VMs so you can quickly reset and practice again
Master the ansible-doc Command
- You have access to ansible-doc during the exam - know how to use it efficiently
- Practice: ansible-doc -l (list all modules), ansible-doc <module_name> (get details)
- ansible-doc includes EXAMPLES section at the bottom - these are copy-paste ready snippets
- Know how to search for modules: ansible-doc -l | grep <keyword>
- Use ansible-doc -s <module> for short synopsis format
Time Management Strategy
- You have 4 hours for the exam - this sounds like a lot but goes quickly
- Read ALL tasks first and identify quick wins vs complex tasks
- Do easier tasks first to build confidence and secure points
- If stuck on a task for more than 15-20 minutes, move on and return later
- Save at least 30 minutes at the end for testing and verification
- Test every playbook/role after creation - don't assume it works
YAML Syntax Mastery
- YAML syntax errors will cause immediate failures - be meticulous
- Use spaces, never tabs (set up your editor to insert spaces)
- Always use ansible-playbook --syntax-check before running
- Be consistent with indentation (2 spaces is standard)
- Quote strings when they contain special characters (especially colons)
- Practice writing YAML by hand, not copy-paste, to build muscle memory
Idempotency is Key
- Run every playbook at least twice to verify idempotency
- Second run should show all tasks as 'ok' with no 'changed' states
- Use appropriate modules that are inherently idempotent (yum, service, user, etc.)
- Avoid using shell/command modules unless necessary - they're not idempotent by default
- Use creates/removes parameters with shell/command for idempotency
- Test with --check mode to verify no unexpected changes
Documentation and Organization
- Bookmark important documentation pages in your browser before the exam if allowed
- Organize your work directory logically: separate directories for different tasks
- Use meaningful names for playbooks and files that indicate their purpose
- Comment your playbooks for clarity, especially complex conditionals
- Keep a terminal window open with common commands you might need
- Create a quick reference file with module syntax during practice
Common Pitfalls to Avoid
- Not testing privilege escalation - always verify become works correctly
- Forgetting to gather facts when you need them - some tasks require ansible facts
- Using wrong variable syntax in templates {{ }} vs tasks {{ }}
- Not properly escaping special characters in Jinja2 templates
- Incorrect file permissions on vault password files (should be 600)
- Missing the 's' in hosts: in playbooks (common typo)
- Not verifying SSH connectivity to all managed nodes before starting tasks
Exam Environment Preparation
- Memorize the standard role directory structure - you need to create this from scratch
- Practice typing commands quickly but accurately - speed matters
- Know how to troubleshoot SSH issues rapidly (ssh -v for verbose output)
- Understand variable precedence - which variables override others
- Be comfortable with vi/vim - it will be your primary editor
- Test your solutions from a clean state to ensure reproducibility
Exam Day Tips
- 1Arrive early and ensure your test environment is stable if remote, or arrive at test center with time to spare
- 2Read the entire exam scenario and all tasks before starting - understand the big picture
- 3Note down the scoring weight of each task - prioritize high-value tasks
- 4Verify you can SSH to all managed nodes at the start - fix connectivity immediately if broken
- 5Use ansible -m ping all to verify basic connectivity before doing anything else
- 6Create a simple checklist for each task and mark them off as you complete them
- 7Always run playbooks with --syntax-check first, then --check mode, then actual execution
- 8Test every solution by running the playbook a second time to verify idempotency
- 9If a task asks for specific output or configuration, verify it manually on the managed nodes
- 10Keep calm if something doesn't work immediately - debugging is part of the exam
- 11Document your ansible.cfg and inventory file locations carefully
- 12Save your work frequently and create backups of working configurations
- 13Use descriptive names for all files so you can find them quickly later
- 14Don't spend too much time perfecting one task - partial credit is better than no credit
- 15In the final 30 minutes, review all tasks and test solutions you're unsure about
- 16Verify that all required files are in the specified locations mentioned in tasks
- 17Check that all services are enabled and started, not just started
- 18Ensure proper file ownership and permissions where specified
- 19Reboot managed nodes if required by tasks and verify configurations persist
- 20Trust your preparation - if you've practiced extensively, you know this material
