At standup, a dev groups related components and deploys them together as a higher-level unit. What is this called?
A Terraform stack is a higher-level construct that groups components and manages multiple deployments of them. It raises the abstraction above individual root modules. Stacks target managing infrastructure at scale.

During a design review, a stack references reusable infrastructure modules as building blocks. What are these called?
Within a stack, a component wraps a Terraform module and its inputs as a reusable unit. The stack composes components into the overall infrastructure. This separation keeps stacks modular.

In a PR review, the team rolls out the same stack to dev, staging, and prod. What represents each target?
Each environment a stack is rolled out to is a deployment, configured with its own variables. One stack can drive many deployments. This models multi-environment rollouts cleanly.

An incident report shows a plan blocked because an upstream value isn't known yet. Which Stacks feature handles this?
Terraform Stacks support deferred changes, allowing planning to proceed when some values are not yet known and applying them once available. This avoids brittle ordering hacks. It is key for dependent, staged rollouts.
5 / 5
During a code review, the team relies on Stacks to coordinate dependencies across components. What is this responsibility?
Stacks provide orchestration, sequencing component changes and propagating outputs as inputs across the stack. This automates dependency management that was previously manual. It is a primary reason to adopt Stacks for large estates.
