Module 2 challenge :Configuration Management and the Cloud (Google IT Automation with Python Professional Certificate) Answers 2025

1. File extension for Puppet manifest
✔️ .pp
❌ .mf
❌ .txt
❌ .pup

2. Purpose of require and notify
❌ Not about absence or emails
❌ Not about usernames/passwords
❌ Not about logging levels
✔️ Create dependencies and ensure correct order; notify refreshes service

3. Puppet module file locations

• init.pp → manifests/ (defines a class with the same name as the module)

• vhost.conf.erb → templates/ (contains placeholders for agent-specific data)

• ntp.conf → files/ (copied to agent as-is)

4. Avoid duplicating common configurations
❌ Not avoiding multiple node definitions
❌ base.pp in top-level folder only
❌ Copy/paste classes in each node
✔️ Define a global base class in site.pp and include it in node definitions

5. Cryptographic security for node authentication
❌ FQDN
❌ Token authentication
❌ SSO
✔️ PKI (Public Key Infrastructure)

6. Puppet agent auto-check configuration
❌ sudo puppet update --auto
❌ sudo puppet config --enable/start
❌ sudo systemctl puppet
✔️ sudo systemctl enable puppet + sudo systemctl start puppet

7. Purpose of --noop parameter
❌ Not defining operations to avoid
❌ Not adding conditional rules
✔️ Simulates manifest evaluation without taking action
❌ Not passing a variable

8. Capabilities & limitations of testing approaches (select all that apply)
❌ Running on test machines eliminates other testing
❌ --noop perfectly substitutes for test machines
✔️ RSpec verifies catalog resources & attributes
✔️ puppet parser validate checks syntax but not logical correctness

9. Recommended way to apply updates to a fleet
❌ Don’t update existing services
❌ Wait for many changes before updating
✔️ Apply smaller changes incrementally
❌ Notify users to decide

10. Importance of default node (select all that apply)
✔️ Acts as a catch-all for unmatched nodes
❌ Not mandatory only for Puppet master
✔️ Ensures basic config for new nodes
❌ Puppet master can generate catalog without default node
