What does the reusability principle in IaC primarily enable?

Writing a new script for each environment to ensure uniqueness

Using the same infrastructure code across multiple environments or projects

Executing infrastructure code only once to avoid side effects

Storing all infrastructure code in a single large file

A large enterprise has multiple teams that each manage their own infrastructure. They want to enforce standard security policies across all teams, but they also want to allow teams to customize their deployments. They plan to use IaC. What is the best way to balance standardization and flexibility?

Create a single, monolithic configuration that all teams must use without modification.

Use a configuration management tool to enforce policies on servers after they are deployed.

Allow each team to write their own configuration from scratch, with no shared components.

Create a set of reusable modules that implement the standard policies, and allow teams to use them with their own parameters.

A company has multiple business units that each need a standard web server setup with the same security groups and load balancer configuration. They want to reduce duplication and ensure that security updates are applied uniformly. What is the most effective IaC approach?

Write a separate configuration for each business unit, copying the common parts.

Create a shared module that defines the web server stack and reference it from each business unit's configuration.

Use a single configuration that deploys all business units' resources together.

Use a configuration management tool to enforce the desired state on each server individually.

How does immutability contribute to maintaining stable environments?

By automatically rolling back any failed deployment

By preventing unauthorized changes to running infrastructure

By allowing direct SSH access to servers for troubleshooting

By storing all configuration in a central database
