Infrastructure as Code Concepts
1 topic
IaC Fundamentals
- Describe the concept of Infrastructure as Code and explain how it enables version-controlled, repeatable infrastructure provisioning compared to manual configuration
- Identify the advantages of IaC patterns including consistency, reproducibility, collaboration through version control, and automated compliance enforcement
- Explain the difference between declarative and imperative IaC approaches and describe how Terraform's declarative model defines desired end-state rather than procedural steps
- Analyze the risks of infrastructure drift and evaluate how IaC tools detect and remediate configuration differences between declared state and actual infrastructure
- Describe the concept of idempotency in IaC and explain how Terraform ensures that applying the same configuration multiple times produces the same infrastructure state
2
Terraform Purpose and Use Cases
1 topic
Terraform Value Proposition
- Describe Terraform's cloud-agnostic approach and explain how provider plugins enable infrastructure management across multiple cloud and on-premises platforms
- Explain the benefits of Terraform for multi-cloud infrastructure management including consistent workflow, provider ecosystem, and state-based change tracking
- Analyze scenarios to determine when Terraform is the appropriate tool compared to cloud-native IaC tools such as CloudFormation, ARM templates, or Deployment Manager
3
Terraform Basics
3 topics
Providers and Resources
- Describe the role of Terraform providers and explain how provider blocks specify source, version constraints, and authentication configuration
- Implement resource blocks using HCL syntax to declare infrastructure components with required and optional arguments and meta-arguments
- Implement data source blocks to query existing infrastructure and reference returned attributes in resource configurations
- Implement resource dependencies using depends_on and implicit references to control creation and destruction ordering between resources
- Implement provider aliases to configure multiple instances of the same provider with different configurations for multi-region or multi-account deployments
Variables and Outputs
- Implement input variables with type constraints, default values, descriptions, and validation rules to parameterize Terraform configurations
- Describe the variable definition precedence order including environment variables, terraform.tfvars, auto.tfvars, and -var command-line flags
- Implement output values to expose resource attributes and computed values for use by other configurations, modules, or external systems
- Implement local values using the locals block to simplify repeated expressions and intermediate computations within configuration files
- Implement sensitive variables using the sensitive flag to prevent values from appearing in plan output and apply logs while still using them in configuration
Provisioners and Terraform Settings
- Describe the purpose and limitations of provisioners including local-exec and remote-exec and explain why they are considered a last resort in Terraform
- Implement the terraform settings block to specify required provider versions, required Terraform version, and backend configuration
4
Terraform CLI Outside Core Workflow
1 topic
CLI Utility Commands
- Implement terraform fmt to automatically format configuration files to canonical style and explain its role in maintaining consistent code style across teams
- Implement terraform import to bring existing infrastructure under Terraform management by mapping real resources to configuration resource addresses
- Implement terraform workspace commands to create, select, and manage multiple named workspaces for environment isolation within a single configuration
- Implement terraform taint and untaint to mark resources for forced recreation and explain how terraform apply -replace supersedes taint in newer versions
- Implement terraform console for interactive expression evaluation and debugging of HCL expressions, functions, and variable interpolations
- Implement terraform output to query output values from state and explain how outputs integrate with shell scripts and other automation tooling
5
Terraform Modules
1 topic
Module Sources and Usage
- Describe the purpose of Terraform modules and explain how they enable reusable, composable infrastructure patterns with encapsulated configuration
- Implement module blocks using different source types including local paths, Terraform Registry, GitHub, and S3 bucket sources with version constraints
- Implement module inputs by passing variable values and consume module outputs to reference child module resource attributes in root configuration
- Describe variable scope within modules and explain how root module variables, child module variables, and output values create explicit interfaces between modules
- Analyze module design decisions to evaluate when to use published registry modules versus custom modules based on organizational requirements and customization needs
6
Core Terraform Workflow
2 topics
Init, Plan, Apply
- Describe the core Terraform workflow of Write, Plan, and Apply and explain how each phase contributes to safe, predictable infrastructure changes
- Implement terraform init to initialize a working directory including provider plugin installation, module download, and backend configuration
- Implement terraform plan to generate an execution plan and interpret the output including create, update, destroy, and replace actions on resources
- Implement terraform apply to execute infrastructure changes and explain auto-approve mode, plan file usage, and the confirmation prompt behavior
- Implement terraform destroy to decommission managed infrastructure and explain targeted destroy and the relationship between destroy and apply -destroy
- Implement targeted operations using -target to apply changes to specific resources and explain when targeted apply is appropriate versus full configuration apply
Validate and Format
- Implement terraform validate to check configuration syntax and internal consistency without accessing remote state or provider APIs
- Analyze a terraform plan output to identify unexpected resource changes, potential downtime risks, and data loss from resource replacement versus in-place update
7
State Management
2 topics
State Concepts and Backends
- Describe the purpose of Terraform state and explain how it maps configuration to real-world resources, tracks metadata, and enables dependency resolution

- Implement remote backend configuration to store state in a shared location with state locking to prevent concurrent modification conflicts
- Describe how sensitive data appears in Terraform state files and explain strategies for protecting state including encryption at rest and restricted access policies
- Describe state locking mechanisms and explain how different backends implement locks to prevent concurrent state modifications by multiple operators
State Operations
- Implement terraform state commands including list, show, mv, and rm to inspect and manipulate resources within the state file
- Analyze state drift scenarios where real infrastructure has diverged from state and determine the appropriate remediation using refresh, import, or manual state editing
8
Read, Generate, and Modify Configuration
2 topics

- Implement complex variable types including list, map, set, object, and tuple and explain how type constraints enforce configuration structure
- Implement for_each and count meta-arguments to create multiple resource instances from collections and explain the trade-offs between each approach
- Implement dynamic blocks to generate repeated nested blocks within resource configurations based on variable input collections
- Implement HCL expressions including conditionals, for expressions, and splat expressions to transform and filter data within configurations
- Implement moved blocks to refactor resource addresses without destroying and recreating infrastructure when reorganizing configuration structure
Functions and Configuration Patterns
- Implement built-in Terraform functions including string, numeric, collection, encoding, and filesystem functions to manipulate values in configuration
- Implement the templatefile function to generate dynamic configuration content from template files with variable interpolation
- Implement lifecycle meta-arguments including create_before_destroy, prevent_destroy, and ignore_changes to control resource behavior during updates
- Analyze configuration patterns to identify opportunities for refactoring using modules, for_each, and dynamic blocks to reduce duplication and improve maintainability
