CV0-004 Deployment Practice Question
A DevOps team uses CloudFormation to manage multi-account infrastructure. They need to deploy a common set of resources across multiple AWS accounts in an organization. Which CloudFormation feature should they use?
⚠ Common exam trap
The trap is confusing nested stacks (intra-account template composition) with StackSets (cross-account/cross-region deployment) — both involve 'stacks' but solve entirely different problems.

Correct answer & explanation
✓
Stack sets
CloudFormation StackSets allow a single template to be deployed across multiple AWS accounts and regions from a central administrator account, which is exactly what the DevOps team needs for multi-account infrastructure. StackSets support automatic deployment to new accounts as they join the organization and can use service-managed permissions for Organizations integration. This makes it the correct feature for cross-account, multi-region rollouts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Nested stacks
Why it's wrong here
Nested stacks compose reusable templates within a single account and region; they cannot target multiple AWS accounts. It tempts because nested stacks promote resource reuse, which matches the 'common set of resources' phrasing, but cross-account deployment requires StackSets.
- ✗
Drift detection
Why it's wrong here
Drift detection identifies where deployed resources diverge from their template, it does not deploy anything. It tempts because drift detection is valuable for maintaining consistency across stacks, but the requirement is initial deployment of common resources into multiple accounts, which StackSets performs.
- ✓
Stack sets
Why this is correct
Stack sets let a single CloudFormation template deploy identical resources across many AWS accounts and regions from one administrator account. This satisfies the stem's requirement for consistent multi-account deployment, unlike ordinary stacks, which are scoped to a single account.
- ✗
Change sets
Why it's wrong here
Change sets preview how a stack update will alter existing resources before execution; they do not deploy across accounts. It tempts because change sets are used to validate updates safely, but multi-account deployment requires StackSets with organisational targets.
